Hi, I have a Sonus SBC SweLite and SfB Server 2015, which failing for calls coming from 4g VOLTE devices, however the invite is offering 0 and 8 in the invite but SfB isn't selecting this codec and providing a "SIP/2.0 488 Invalid incoming Gateway SDP:
Invalid media" response. If 4g is disabled the call is correctly coded through. Below are the 2 invites being offered, I'm unsure why isn't selecting G.711 A law or U law as they are offered in both instances.
