Progress Ind i = 0x8482 - Destination address is non-ISDN
The Only difference I can see is that the new system sends an Setup ACK message. However I am unable to ascertain what information is missing. Does anyone know if there is a setting I can change in the Service Parameters that needs to be changed????
No information is missing, CM is misbehaving. It expects channel information to be in Call Proceeding and not in Setup Acknowledge, however per Q.931 standard, it can be in either message (that incidentally, convey slightly different semantic).
I'm unable to tell you why, and if it is fixable.
I would recommend stay with H.323, more features, more stability, easier to configure and troubleshoot.
Thanks for the reply, unfortunately as the Telco Provider I have to carry out User Acceptance Testing for CallManager and this is a fail. As such I either need to find a fix for this or state that CallManager will not work with the Telco Switch we provide as a MGCP option
