Thanks for your answer.
I am using CUCM (jabber) agents. When dialing from one Jabber to the service and the agent is available, the call comes in correctly although ICM label is AgentID and not Agent Extension.
When CVP s used (prompts ...), the problem appears.
Checking CUCM sip trunk towards CVP it is down with code 503 (service unavailable).
When checking CVP call server I see this errorin the log:
137: 10.254.5.23: Aug 22 2016 17:53:59.075 +0200: %CVP_11_0_SIP-3-SIP_INTERNAL_ERROR: ICM Messagebus Plugin is down , Unable to publish GatewayEvent report [id:5005]
Any suggestion is appreciated.
thanks and regards
