## Instant Message

This section describes the Instant Messaging functionality of Oracle Communicator.

Figure 4-5 Sending an instant message

Description of "Figure 4-5 Sending an instant message"

### Introduction

Use Instant Messaging to send and receive text messages from your Contacts. Oracle Communicator not only enables you to transmit text messages, but you can switch to an audio and/or video call from the Instant Messaging window, exchange audio messages, and even do file transfer.

#### Send an Instant Message

You can send instant messages to your Contacts, or anyone else with a SIP address. There are two kinds of instant messages: text messages and voice messages.

To send an instant text message to a Contact in your Contact List, double-click the Contact name. The Communication dialog appears. Enter a text message in the lower part of the dialog and click Send. Your message has been received by the recipient when it appears in the Message area.

You can also add smileys to your messages. Just click on the Smiley icon and choose one of the Smileys that appear.

When you close a Message dialog, you are prompted to confirm that you want to exit the conversation.

From the Communication dialog you can start a telephone or video call to the same Contact with whom that you are chatting.

##### Send IMs to People Not in your Contact List

To send an instant message to someone not in your Contact List, enter a SIP address in the Quickdial text box in the Main window and select Send Message... from the Communicate menu to the right of the text box. The Communication dialog appears. Write your text message in the lower part of the dialog and click the Send button. Your message has been received when it appears in the Message area.

##### Quickdial Query

In the Slate theme, Quickdial displays a list of Contacts matching your input. For example, if you wanted to see all of the Contacts whose names began with jo, you would enter those letters into the Quickdial field. Contacts matching the letters are displayed.

Figure 4-6 Quickdial

Description of "Figure 4-6 Quickdial"

If there aren't any matches, then a list of recently entered values is displayed.

##### Send a Message to non-Oracle Communicator Users

To send an instant message to someone not in your Contact List, enter a SIP address in the Quickdial text box in the Main window and select Send Message... from the Communicate menu to the right of the text box. The Communication dialog appears. Write your text message in the lower part of the dialog and click the Send button. Your message has been received when it appears in the Message area.

#### Send a Voice Message

In addition to sending instant messages as text, you can record and send voice messages.

Figure 4-7 Voice message

Description of "Figure 4-7 Voice message"

To do so, click the Voice tab in the lower part of the dialog (in the Slate theme, click the Show Voice Message Panel button). You will see the voice message controls that you use when you are working with voice messages.

When you receive a voice message you can see how long the message is (in seconds). Click on the voice message link to play the message. Use the controls to play the message again if you like.

Instead of recording your own message, you can load a voice message from file. From the File menu, click the Load button and select the file you want to load. The file must be in .wav format.

Note that not all Contacts may be able to receive voice messages; it depends on the equipment they use.

Also note that the duration of voice messages is limited to one minute.

##### Record a Voice Message

Click the Record button and speak your message in the microphone. When you are done, click the Stop button. Before you send the voice message, you can listen to it by clicking the Play button. To send the voice message, click the Send button. Your message has been received by the recipient when it appears in the Message area.

##### Save Voice Messages

If you have listened to a voice message and want to save it, click the Save button and select were the file should be saved. The voice message will be saved as a .wav file, which can be played in most sound applications.

#### Smileys

To add smileys to your message, click the Smiley button in the Communication dialog and select the smiley of your choice.

Description of "Figure 4-8 Smileys"

## Telephony

Telephony refers to the telephone-calling features of Oracle Communicator. This section describes the powerful features of Oracle Communicator telephony.

Note:

This feature relies on a dialout SIP Servlet deployed and configured on the SIP server to handle SIP INVITES.

### Introduction

Oracle Communicator enables you to make voice calls to other Oracle Communicator users, fixed phones and mobile phones (Your service provider must configure Oracle Communicator to make use of this functionality.). You need speakers and a microphone on your computer, or as recommended, a headset connected to your computer, to use the phone in the application.

#### Make an Audio Call

Before making a call, ensure that your speakers and microphone are connected and turned on.

To call a Contact, select the Contact from the Contact List. Right-click the Contact and select Call from the Context menu. If the Contact you selected has several possible addresses to call, for example both a SIP address and a telephone number, select which one you want to use; the Communication dialog appears and the Contact's phone starts ringing.

You can also double-click the Contact (which opens the Communication dialog) and then click the Call button. Note that when calling from the Communication dialog, the call is placed to the SIP address even if this Contacts has a specified phone number in contact properties.

You will be notified of the status of the call with sounds and text messages in the status bar in the Communication dialog.

Click the Hang-up button or close the Communication dialog to end a call. The call duration is shown in the dialog during and after the call.

##### Communication Dialog

To call someone you do not have in your Contact List, enter a SIP address or phone number in the Quickdial field, and click Call from the Communicate menu. The Communication dialog appears and the person's phone starts ringing.

##### Use Quickdial

*In the Slate theme, Quickdial displays a list of Contacts matching your input. For example, if you wanted to see all of the Contacts whose names began with jo, you would enter those letters into the Quickdial field. Contacts matching the letters are displayed.

If there aren't any matches, then a list of recently entered values is displayed.

#### Answer an Audio Call

When someone calls you, you will hear a ringing signal (if your speakers are turned on), and a message pops up to notify you that you have a call. Click the pop-up, and the Communication dialog appears.

Click the Answer Call button to answer the call. Make sure your speakers and microphone are connected and turned on.

Click the Decline button if you want to decline the phone call; the other party will be notified of the decline.

Note that if you chose to have your call automatically answered, Oracle Communicator will automatically answer all incoming calls. If you close the Communication dialog for an incoming call, the call will automatically be declined.

You will be notified of the status of the call with sounds and with text messages in the status bar of the Communication dialog.

Click the Hang-up button or close the Communication dialog to end a call. The call duration is shown in the dialog during the call and after a call. Note that until you answer the call, call settings (such as Sound Effect, Mute, and Dial Pad) are not available.

#### Put a Call on Hold

When in a call you can make another call by putting the current call on hold. Click Hold from the Communication dialog to put a call on hold. The other party is notified with a sound and a pop-up when you put them on hold. If you put a video call on hold, the videos of the callers will not be visible until you resume the call. You can make another phone call or video call, to someone else, while the first call is on hold.

Figure 4-9 Putting a call on hold

Description of "Figure 4-9 Putting a call on hold"

Click Resume to pick up a call that has been put on hold.

Note that only the person who put the call on hold can pick it up again by clicking Resume. You can only have one active call at a time; other calls will automatically be put on hold. You can for example be active in one call and have another call on hold. If you then click Resume on the call that was on hold the active call will automatically be but on hold.

A call on hold is still an ongoing call; you must click Hang-up or close the Communication dialog to end the call. The call duration is shown in the dialog during the call and after a call.

#### Hang Up

When a call is on hold, other features (such as Sound Effect, Mute, and Dial Pad) are not available. When you resume the call, these features will again be available.

#### Call Waiting

If someone calls you while you are in a call, you will be notified of the new incoming call with a sound and a pop-up in the task bar indicating the new call and who is calling.

To answer the new incoming call you can either:

- Choose to end the ongoing call by clicking Hang-up on this call's Communication dialog and then answer the new incoming call in the incoming call's Communication dialog.

- Answer the new incoming call. The first ongoing call will automatically be put on hold when answering the second call. You can switch back to the first call by clicking Resume on this call's Communication dialog. Note that you can only have one active call at a time; other calls will automatically be put on hold. You can switch between the calls as many times as you want.

Note:

A call on hold is still an ongoing call and that you must click Hang-up or close the Communication dialog to end the call. The call duration is shown in the dialog during the call and after a call.

#### Dial Pad

Oracle Communicator supports DTMF tones (which you sometimes use for certain telephony services). To use DTMF tones in a call click Dial Pad in the Communication dialog and click the numbers.

Note that you can enter a plus sign (+) for international dialing by using your keyboard, or by pressing and holding down the zero key on the dialpad. Top-row number keys can be used when Dialpad is active.

#### Sound Effects

When you are in a call, you can add sound effects which will be heard by both you and the Contact with whom you are talking.

Figure 4-10 Sound effects

Description of "Figure 4-10 Sound effects"

To mix a sound effect in your call click the Sound Effect button or the Sound Effect menu at the top of the Communication dialog. The menu with the sound effects will be displayed. Select the sound effect you want, and the sound will be mixed in your call.

When the sound effect is playing, you can stop it by selecting Stop Sound Effect in the Sound Effect menu.

Oracle Communicator includes a number of built-in sound effects, but you can also use your own sounds. To mix your own sound effect in a call, select Load and Play Sound Effect from the Sound Effect menu. Then select a .wav file you want to use. When you have selected the file, it will be loaded and played immediately. The menu will be updated with a history of sound files that you have used as sound effects.

#### Mid-call Control

You can use Mid-call Controls if your service provider supports them. The services that are available and the service activation codes depend on the service provider.

Figure 4-11 Mid-call control

Description of "Figure 4-11 Mid-call control"

For a complete list of available services, ask your service provider.

To use Mid-call Control services during a call:

1. Open the Dialpad in the Communication dialog.

2. Press the R button on the Dialpad.

3. Type the service activation code on the Dialpad.

#### Add Video to an Ongoing Phone Call

You can add video to an ongoing phone call by clicking the Add Video in the Communication dialog. The other party will be asked to join the video call. If accepted, the video call begins. If declined, the call continues as a voice call. You can remove the video and switch back to a regular phone call again at any time.

#### Voice Mail Notification

If your service provider supports voice mail, the Voice Mail Notification button will be visible to the right of the Communicate menu.

If someone has left voice mail for you, Oracle Communicator indicates that you have new messages waiting for you by changing the appearance of the Voice Mail Notification button:

Note that the look of the buttons may vary depending Theme.

To listen to your voice mail messages, click the Voice Mail Notification button.This makes a call to your voice mailbox. When the call is answered, follow the instructions to listen to any messages stored in the mailbox.

If you hover over the Voice Mail Notification button, you can see how many voice mail messages are stored in your mailbox.

Voice mail may not be supported by all service providers, so this feature may or may not be available to you, depending on your provider.

#### Ring Signals

You can select which ring signal should be played when a Contact calls you. It can be different ring signals for different Contacts, or the same for all Contacts.

1. Right-click on the Contact for whom you want to assign ring signals, and select Properties... in the menu. The Contact Properties dialog appears.

2. At the bottom of the dialog, select the ring signal you want to use for the Contact. This can be one of the built-in ring signals, or you may choose your own signal. To choose your own signal, select Select Other... then locate the .wav sound file that you want to use as a ring signal. The sound will be looped, so not all sound files are suitable as ring signals.

The selected ring signal can be tested by clicking the Play button to the right.

##### Set a New Default Ring Signal

If you haven't set a ring signal for a Contact, the default ring signal will be used. You can change the default ring signal in Preferences.

#### Call Settings

There are some phone and video call settings you can make in the Communication dialog for ongoing calls:

- Speaker sound controls can be modified by dragging the Volume controls.

- To mute outgoing audio for an ongoing, call click Mute.

- To freeze the outgoing video image, that is the video image from your video camera, click Freeze.

Other audio settings can be made in the audio preferences from the main window, and other video settings can be made in the video preferences from the main window.

## Video

Oracle Communicator enables you to transmit and receive video with your Contacts. It's as easy as making a phone call.

### Introduction

You can easily make video calls to someone with a SIP address or to a video conference bridge from Oracle Communicator. One party to the conversation must have a camera in order to participate in a video call.

Figure 4-12 Video call

Description of "Figure 4-12 Video call"

#### Make a Video Call

To make a video call, start by making sure you speakers, microphone and (optionally) web camera are connected and turned on.

Note:

One-sided video calling is possible. That is, if one person on the call has a video camera and wants to display their video, they may do so; it is not necessary for both callers to have video cameras. Both Contacts must have a SIP address.

To make a video call to a Contact, select the Contact from the Contact List. Right-click the Contact and select Video Call from the Context menu. The Communication dialog appears and the Contact is notified. You can also double-click the Contact which opens the Communication dialog and then click the Video Call button.

To call someone you do not have in your Contact List enter a SIP address or number to a video conference bridge in the Quickdial text box and click Video Call from the Communicate menu. The Communication dialog appears and the person is notified.

The video call will be set up when the other party answers. If they are transmitting video, you will see them. You will also be able to see a self-view image from your web camera.

You will be notified of the status of you video call with sounds and text messages in the status bar at the bottom of the Communication dialog.

Note:

In the Slate theme, Quickdial displays a list of Contacts matching your input. For example, if you wanted to see all of the Contacts whose names began with jo, you would enter those letters into the Quickdial field. Contacts matching the letters are displayed:

If there aren't any matches, then a list of recently entered values is displayed.

Click the Hang-up button to end a call. The call duration is shown in the dialog during the call and after a call.

#### Answer a Video Call

When someone invites you to a video call, you will hear a ringing signal and a message will pop up. Click the pop-up, and the Communication dialog appears showing who is calling you.

Click the Answer Video button to answer the video call. You can also answer the call as audio-only if you wish (by clicking the Audio Call button). Make sure your speakers, microphone and (optionally) web camera are connected and turned on. The video call will begin when you answer and you will be able to see the caller's web camera image in the Video area. You will also be able to see a self-view image from your web camera (if you are using a web camera).

Click the Decline button if you want to decline the video call; the other party will be notified of the decline.

Note that if you close the Communication dialog for an incoming video call the call will automatically be declined.

You will be notified of the status of the video call with sounds and text messages in the status bar at the bottom of the Communication dialog.

In the Slate theme, video windows are displayed or dismissed automatically when you are in (or exit) a video call. In the Communicator theme, a a video toggle arrow button enables you to show or hide the video pane.

The other party is notified with a sound and a pop-up when you put them on hold. If you put a video call on hold, the videos of the callers will not be visible until you resume the call. You can make another phone call or video call, to someone else, while the first call is on hold.

Click Resume to pick up a call that has been put on hold.

Note that only the person who put the call on hold can pick it up again by clicking Resume. You can only have one active call at a time; other calls will automatically be put on hold. You can for example be active in one call and have another call on hold. If you then click Resume on the call that was on hold the active call will automatically be but on hold.

A call on hold is still an ongoing call; you must click Hang-up or close the Communication dialog to end the call. The call duration is shown in the dialog during the call and after a call.

## Troubleshooting

This section contains some tips to help you if you encounter a problem. Sections include:

- Presence

- Messaging

- Calling

### Presence

Presence troubleshooting tips:

#### Cannot Register

There are several different things that can cause this problem:

- No network connection: Make sure your dial up connection or network connection is working. See your PC documentation for more details on configuring your network connection.

- Faulty proxy settings: Make sure your proxy settings are correct. If you do not use a proxy, ensure that you have not checked the Use Proxy Server option in Preferences under Settings in the Main window.

- Wrong SIP address: The presence server is determined from your SIP address. If it has been incorrectly entered, then the server will not be found. Create a new account with the correct SIP address.

- Server problem: The presence server you want to use might be unreachable.

Contact your service provider for support if the problem persists.

#### Cannot Authenticate

Make sure your username and password are entered correctly. These are usually provided by your service provider.

Contact your service provider for support if the problem persists.

#### Cannot See Anyone in My Policy List

If your Presence Policy list is empty or incomplete, first make sure you are registered. The Presence Policy list is only populated once you have been successfully registered to the server. If you are registered, then the client may be having trouble downloading your policy from the server.

Contact your service provider for support if the problem persists.

### Messaging

Messaging troubleshooting tips:

#### Message Delivery Failed

If you are successfully registered then this problem may occur if the contact you are chatting with has gone offline. If you are not registered to the server, check the troubleshooting tips for not being able to register and try again.

### Calling

Calling troubleshooting tips:

#### No Ringing Signal

Make sure your speakers are connected, turned on and are functional. If you do not get a ringing signal when trying to call, you may not be successfully registered to the server. See the troubleshooting tip for registration.

#### Very Loud Signal on Incoming Call

The application can send a beep to the PC internal speakers so that you do not miss a call when your headset is connected but you are not using it. Some hardware does not support this feature, and will play the beep very loud in the headset. You can turn this beep off.

#### Echo When in a Call

The application supports echo suppression and echo cancellation. To turn on echo cancellation (for example when using your PC as a speaker phone), see the audio preferences.

#### Busy Signal

If you immediately get a busy signal, the other party is already engaged in a call and cannot answer. The busy signal can also indicate that the other party has chosen to decline your call. In the latter case, the busy signal appears after the normal ringing tone.

#### Info Tone

Sometimes you can hear a special info tone, with three raising signals repeated over time. You hear this sound when there are other problems. Examples of such problems are:

- The SIP address or telephone number does not exist. Check the address or number and try again.

- The user of the SIP address is not registered and can not be called. Check the user's presence and try again when the user is available.

- The other party cannot take your call, perhaps due to technical reasons.

- There can be some server or network problem between you and the one you are trying to call. Try again later.

#### No audio or Video

If you are in a call and can not hear, be heard by, or see the other party:

- Make sure your speakers and microphone are connected, turned on and work.

- Make sure the other party's speakers and microphone are connected, turned on and work.

- Make sure cameras being used function, and have the right drivers. Try the camera in another application.

- Make sure that you or the other party has not turned on mute. In this case click Unmute in the Communication dialog.

- If the video image you see from the other party does not move, the other party may have chosen to freeze her or his video image. See video settings.

- If the video image from your web camera does not move, you may have frozen your video image. In this case click Unfreeze in the Communication dialog.

Contact your service provider for support if the problem persists.
