Don't receive any valid presence status from Innovaphone via WebSocket                
                
    Hi there,
We have a CC solution communicating to Innovaphone pbx via WebSocket using RCC, PbxApi. 
This is the Subscribe request we send to Innovaphone pbx using user's phone number:
var subscribe = new SubscribePresence
                        {
                            src = "80141",
                            num = "80141"
                        };
This is we receive for "PresenceState":
  "mt": "PresenceState",
  "up": true,
  "sip": "j80141",
  "dn": "Josie80141",
  "email": null,
  "api": "PbxApi",
  "src": "80141"
This is we receive for "PresenceUpdate":
"mt": "PresenceUpdate",
  "presence": [
    {
      "contact": "tel:",
      "status": "closed",
      "activity": null,
      "note": null
    },
    {
      "contact": "im:",
      "status": "closed",
      "activity": null,
      "note": null
    }
  ],
  "api": "PbxApi",
  "src": "80141"
We don't receive any update if the user is on call or change note or activity on the phone
Could you please let me know what we have done wrong?
Many thanks!
