Luckily, there is an option to force Asterisk to ignore the SDP

COOL!!! OK, so
Michael,
It looks like your problem is caused by a phone with a non-standard

Michael,
Here are the differences between the systems that I determined from the two SIP
traces:
* Working system: no NAT, phone codec: G.729, Asterisk codec: G.729
* Non-working system: NAT, phone codec: G.729, Asterisk codec: A-law

Absolutely nothing, unlike the working system, where the CLI clearly
indicates that MOH is activated

Can you set the phone to G.711 and try making a LAN call on
