Making a call

Call feature is essential for the modern day communication. Call sdk allows users to make a audio/video call with the another sdk users.

warning

Before making the call, make sure you have implemented the helper object.

Make a voice call#

Initiate a call by providing the callee’s user JID into the makeVoiceCall method. Once the call initiated successfully, a callStatusListener callback will be triggered and callee user call status will be received here.

caution

If One to one call feature is unavailable for your plan, then it will throw 403 exception

await SDK.makeVoiceCall(['USER1_JID', 'USER2_JID'...]);

Request Params#

ParamDescriptionTypeRequired
[USER_JID]User JIDArraytrue

Response Format#

{
statusCode: 200, // Number - status code
message: "", // String - Success/Error Message
callType: "", // String - Call Type - "audio"
roomId: "" // String - Unique room ID
}

Response Params#

ArgumentsDescriptionType
statusCodeStatus CodeNumber
messageSuccess/Error MessageString
callTypeCall type value as "audio"String
roomIdUnique IDString
note

To receive the user track, a userTrackListener callback should already be registered in the caller's client app. Whenever you make the call to a user, you will receive your own track and the callee's track in the same callback method. To differentiate the user, You can use the 'localUser' and 'userJid' param. You will receive both Audio and Video track in the same callback method.

Sample Javascript code to play the track#

<html>
<audio id="audio" autoplay playsinline></audio>
<script>
//let track = TRACK_OBJECT from the callback method
//let element = ELEMENT_OBJECT in which you need to play the audio
let stream = new MediaStream([track]);
try {
element.srcObject = stream;
} catch (e) {
try {
element.src = URL.createObjectURL(stream);
} catch (e) {
console.error("Error attaching stream to element", e);
}
}
</script>
</html>

You need to supply the track object which was received in the callback method to the audio element based on the track type that you have received.

warning

You shouldn't play your own Audio track.

Make a video call#

Initiate a call by providing the callee’s user JID into the makeVideoCall method. Once the call initiated successfully, a callback callStatusListener will be triggered and callee user call status will be received here.

await SDK.makeVideoCall(['USER1_JID', 'USER2_JID'...]);

Request Params#

try {
element.srcObject = stream;
} catch (e) {
try {
element.src = URL.createObjectURL(stream);
} catch (e) {
