I’m trying to integrate an Asterisk PBX with a Nortel using SIP.
I can call aout from asterisk to Nortel but the reverse way I can not.
I receive next error message:
Mar 7 07:30:56 DEBUG chan_sip.c: Setting NAT on RTP to 0
Mar 7 07:30:56 NOTICE chan_sip.c: Content is ‘multipart/mixed ;boundary=unique-boundary-1’, not 'application/sdp’
Mar 7 07:30:56 VERBOSE logger.c: Transmitting (no NAT) to 126.96.36.199:5060:
SIP/2.0 488 Not acceptable here
I found some information in other forum. There someone had same problem and when I contacted him he just told me that He modified chan_sip.c in order to make it comaptible. He did not give the full detail…
Thanks in advance…
