I'm just receiving the same reply from Microsoft when a re-invite from PSTN (Proximus) is relayed back by AudioCodes SBC to Microsoft cloud.

Not all calls fail, currently what I know are emergency test calls to 117 in Belgium, after entering a DTMF digit. I could not get other numbers to fail yet.
The re-invite looks completely normal, with public IP in the SDP "c=" parameter.

We turned off Media Bypass on the SBC and also in TAC. The call does not drop and we do not see the 488. Microsoft still working on the ticket.
