main.c compiled on 10:14:11 May 18 2010 with gcc 4.3.2
Using dispatcher module trying to load balance SIP calls across some
Asterisk servers. I have it working fine when I test in this
scenario:
sip phone dial out><asterisk><kamailio><round robin to several asterisk servers
This works stateful and stateless, handles everything gracefully.
This scenario is giving me fits:
sipp dial out><kamailio><round robin to several asterisk servers
I get retransmits on every call back to sipp with errors like
"Discarding message which can't be mapped to a known SIPp call" and
"SIP/2.0 481 Call leg/transaction does not exist"
This happens with kamailio setup stateful or stateless. I'm wondering
if sipp is the problem or just doesn't play well with kamailio?
I've kept the config as simple as possible for testing, it is listed
here http://pastebin.com/BZ8hJvJv
Here is my sipp usage:
sipp -sn uac 10.10.12.53 -i 10.10.14.97 -s 55 -d 7000 -l 10 -r 1 -trace_err
Any insight would be appriciated.
the problem is in your sipp scenario. The uac calls do not map to uas.
kamailio does not reply 481, check the uas scenario, that is the one
that sends back the 481.
Cheers,
Daniel
