Hi,

thanks for replay

•  that SBC is not sending SDP in the 200 OK. Since the 183 Session Progress does not require a reliable response, CUBE is not considering this and disconnecting the call.

• SBC team said that they want CUBE to advertise 100rel in the Initial INVITE.

• We added “voice class sip rel1xx supported” in the outbound voip dial peer.  Post this change, CUBE started including “100rel” in the Supported header.

• Post above changes, SBC starts sending Require:100rel in the 183 session progress and call started working fine.
