Invite with no SDP

Hi there,

I have an issue with a new SIP server added in the network that is working as a predictive dialer. The calls are being generated without SDP by that SIP Server. The call is answered but when the provider generates a re-Invite to renegotiate the codec, it is not answered by the SIP server and the call is being hung up after 10 seconds.

 

 

Another dialer that we have in the same network is working with no problem the only difference is the SDP message included in the first invite.

 

I tried to include the SDP using add-sdp-invite in the sip-interface for the realm for the service provider but now the calls are being rejected by the SBC with a 488 Invalid Session Description.

Howdy, Stranger!
