SDP on 183 or 200 OK (CS 1000)

[pasesanchez]

Hi all,

When I send a basic call request from our SIP server through the CS1K, targeting a PSTN destination, the SIP INVITE is responded to with two 183 Session Progress Provisional response messages from the CS1k. The interesting thing is that the first 183 response contains an SDP message body while the 2nd 183 response does not.

I am wondering if any configuration can be made (where and whath to change) in the CS1K to either limit this to a single 183 response,include an SDP in both 183 provisional responses, or in the 200 ok.

Thanks.
