You can use the telephony session event notifications to catch telephony events to detect participants (added and removed) in a conference call. It is very complicated and I cannot explain how to detect here. Pay attention to the event similar to the example event below when a participant is added to a conference:
{
"uuid": "1025258805069352046",
"event": "/restapi/v1.0/account/80964XXXX/extension/622953XXXXX/telephony/sessions",
"timestamp": "2024-02-27T16:04:52.558Z",
"subscriptionId": "3ca0ec27-a916-4260-82ad-035752e61da2",
"ownerId": "6228832XXXX",
"body": {
"sequence": 9,
"sessionId": "1229016182016",
"telephonySessionId": "s-a0d17b82ddacdz18deb4ee132z1878e190000",
"serverId": "10.13.23.184.TAM",
"eventTime": "2024-02-27T16:04:52.223Z",
"parties": [
{
"accountId": "80964XXXX",
"extensionId": "622953XXXXX",
"id": "p-a0d17b82ddacdz18deb4ee132z1878e190000-1",
"direction": "Outbound",
"to": {
"phoneNumber": "11119",
"name": "Paco Vu",
"extensionId": "622883XXXXX"
},
"from": {
"phoneNumber": "+1650XXXXXXX",
"name": "Agent 122",
"extensionId": "622953XXXXX",
"deviceId": "80254586XXXX"
},
"status": {
"code": "Gone",
"reason": "Conference",
"peerId": {
"telephonySessionId": "s-a0d7bfa2dd198z18deb4fcc72z184536c0000",
"sessionId": "0",
"partyId": "p-a0d7bfa2dd198z18deb4fcc72z184536c0000-2"
},
"rcc": false
},
"park": {},
"missedCall": false,
"standAlone": false,
"muted": false
}
],
"origin": {
"type": "Call"
}
}
}And similar to this example event when a participant is removed from the conference call:
{
"uuid": "6754846377425683265",
"event": "/restapi/v1.0/account/80964XXXX/extension/622953XXXXX/telephony/sessions",
"timestamp": "2024-02-27T16:06:13.233Z",
"subscriptionId": "3ca0ec27-a916-4260-82ad-035752e61da2",
"ownerId": "6228832XXXX",
"body": {
"sequence": 11,
"sessionId": "1229016182016",
"telephonySessionId": "s-a0d17b82ddacdz18deb4ee132z1878e190000",
"serverId": "10.13.23.184.TAM",
"eventTime": "2024-02-27T16:06:13.166Z",
"parties": 2
{
"accountId": "80964XXXX",
"extensionId": "622953XXXXX",
"id": "p-a0d17b82ddacdz18deb4ee132z1878e190000-1",
"direction": "Outbound",
"to": {
"phoneNumber": "11119",
"name": "Paco Vu",
"extensionId": "622883XXXXX"
},
"from": {
"phoneNumber": "+1650XXXXXXX",
"name": "Agent 122",
"extensionId": "622953XXXXX",
"deviceId": "80254586XXXX"
},
"status": {
"code": "Disconnected",
"rcc": false
},
"park": {},
"missedCall": false,
"standAlone": false,
"muted": false
}
],
"origin": {
"type": "Call"
}
}
},The best way to learn about this is to implement the notification, run a test conference call and print out all the events and learn from the event payloads.
You can call the Delete call party API to delete a party (from the original direct call) and that will disconnect that party from the conference call he was added to the conference call.
