I got a new SNOM M65 which works fine for outgoing calls, but incoming
calls never ring at the handset. I captured the SIP traffic and see
that my M65 is replying with an "488 not acceptable here". From what I
read this is usually codec related but both asterisk and the M65 are set
for ulaw as first choice.
I have a SIP trace below. Can someone suggest why the 488 is being
generated?
