Hi

I'm trying to set-up a click to dial service using JTAPI, I don't know where this problem is coming from as I'm new to CUCM can anyone tell me what the problem might be? Here's the error I got from the servlet log:

Hello friends, I have a problem that I have long time unable to solve.

My problem is that all outgoing calls go right from the Cisco CallManager, but the starters never come.

I have a SIP Trunk contracted with a company of you tell me that this is all right but not from the CUCM.

They tell me that to them reaches them the following error from my CUCM.

Got SIP response 503 "Service Unavailable" back from

82.158.145.110:5060

I have been monitoring my CUCM and my log get this data.
