[asterisk-users] SIP bad request

Fri Apr 29 10:33:22 CDT 2011

What I am looking for?  Here is a snippet, with some info obfuscated. I can see the bad request, but why there is such a message isn’t obvious.

Try to look in 'sip set debug peer user4444'.

Hi,

I have been getting reports phones ringing only a tiny moment and then going to voicemail.  CLI output shows:

-- SIP/user4444-0006fcdd is ringing

-- Got SIP response 400 "Bad Request" back from 23.23.23.23

-- SIP/user4444-0006fcdd is circuit-busy

== Everyone is busy/congested at this time (1:0/1/0)

Which does explain it.  How can I find the root cause of “bad request”? Call-limit is very high for this sip user, so I`m not reaching that limit for sure.
