[asterisk-users] 488 Not Acceptable Here

[Jamie A. Stapleton]

A packet capture would be most useful.  Then, you could review your SDP with your provider.

Subject: [asterisk-users] 488 Not Acceptable Here

Hi,

I'm having real difficulty in getting calls to go through with 
Asterisk.  I've managed to check that my SIP connection is made to my 
provider.  Below is an email I received from them:

----------------snip--------------------------------snip--------------------------------snip----------------
I am not certain of the reason for rejection but it has to do with the 
SDP,  it does not seem to be a codec issue, the response is as you have 
seen:

SIP/2.0 488 Not Acceptable Here
Via: SIP/2.0/UDP 
192.168.0.14;received=172.28.20.106;branch=z9hG4bK42d2ea03;rport=60017
From: "Andy" <sip:XXXXX at 192.168.0.14>;tag=as5c784926
To: <sip:YYYYY at 192.168.34.1>;tag=SD24jn898-4C46B8A2-5688CB2-0ADE2C09
Call-ID: 32d506cd3489aa81031937f467ef661e at 192.168.0.14
CSeq: 102 INVITE
Reason: Q.850 ;cause=127 ;text="Interworking, unspecified"
Content-Length: 0

There looks to be a non-standard element in your SDP that is not 
supported by any of the networks.

Which configuration file is possibly incorrect in this scenario?

What dumps are likely to be useful to me?

Thanks,
  Andy
