I am testing CIC 4.0 and the CIC server is responding to the media pack with an error of SIP/2.0 403 Forbidden when a call is trying to be made from the physical phone. I can make a call from the .net client using a station on this media pack so CIC 4.0 seems to be able to talk to it fine. Also this same media pack works fine on CIC 2.4. My best guess is that the CIC 4.0 server is rejecting the SIP invite from this media pack even though I do not appear to have any restrictions on the line access lists, etc. The media pack station is defined in IA as a stand alone station and I would have thought that would "register/allow" it to register with the CIC 4.0, but it must not be enough. Is there something else in IA I need to set to allow this media pack to allo SIP invites from the Media Pack to accepted by the CIC server?

You should be able to turn up logging on TS to 80 to see why TS is denying the call.

What port are you using on the MP124 to contact the IC server? If the default 5060, did you create a new line in the Lines container in IA to allow registrations on that port? If you don't want to do that, you need to change the port on the MP124 to use 8060 when contacting the IC server to register/place calls.

We are getting "No circuit Available" message when we are making out bond call; below I am providing some example call details please check and let me know, is this happening due to any gateway settings? Because customer says they changed some settings but they could not recollect; what exact they did They informed as after this change they are facing this issue.
