Struggling to figure out why the WebRTC softphone fails to register when routed through our BYOC trunks in AP-SE-2. The SIP registration succeeds for PSTN calls, but the softphone client drops the connection immediately after the offer/answer exchange. The client logs show this:
“SIP 488 Not Acceptable Here - SDP negotiation failed”
The SDP payload looks standard. Has anyone seen carrier-specific codec mismatches causing this on Genesys Cloud BYOC?
