Hello Iqbal,

> which icons are available or can i use custom icons.

It is only possible to send a badge count as a digit, that will be displayed as a red badge. The green chakcmark in your initial post is a default phone app marking, that can not be set programmatically from your app.


> I have also another c++ app service. how could i send badge count from there.

1)
For the first, the App Service must publish in the AppInfo message the presence capability:


{
"mt": "AppInfoResult",
"app": "innovaphone-jsbadgeexample",
"info": {
"apis": {},
"presence": true
}
}

Please check the chapter "Publishing app information" on Reference / App Platform Libraries / appwebsocket (https://sdk.innovaphone.com/13r2/sdk/common/lib/appwebsocket.htm) for a code example.

This will notify the PBX that the App Service can handle presence calls for badge counts.


2)
The App Service must establish a presence signalling call on the AppWebsocket, to be able to handle incoming subscriptions from the cleints:

This message must be sent to the PBX:
{"api":"PbxSignal","mt":"Register","flags":"NO_MEDIA_CALL"}


3)
Incoming call setup messages from the clients must be answerded by the App Service with "conn" as signalling type:
{"mt":"Signaling","api":"PbxSignal","call":-1,"sig":{"type":"conn"}}


The call id must be used later for the signalling.

4)
Set the badge count be sending the following message to the PBX (e.g. set count to "2" on call id "-1"):

{
"api": "PbxSignal",
"call": -1,
"mt": "Signaling",
"sig": {
"fty": [
{
"contact": "app:",
"note": "#badge:2",
"status": "open",
"type": "presence_notify"
}
],
"type": "facility"
},
"src": "badge"
