Hello,
I had posted this question earlier on asterisk-users, but didn't
receive any reply, so I'm posting on sr-users in the hope that someone
can provide guidance on how to debug this problem.
Our setup involves a Sip softphone registering with a fresh install of
Asterisk v1.6.0.5 through an outbound proxy (Kamailio v3.1.1).
We observe that about 80% of the time, immediately after startup of the
softphone, when the softphone sends a REGISTER message, Asterisk
replies with a "503 Server error". However, subsequent REGISTER
messages are replied to appropriately (with a 401 Unauthorized).
There are very few devices (under 5) registered with Asterisk, so this
is not an overload issue.
Please find attached a SIP trace for device registration.
- What might cause this behavior in Asterisk ?
- Are there any config file parameters that require to be changed ?
- Would it help to see any other specific logs, if so which ones ?
you should set sip debug on for asterisk in order to get more verbose
output related to the 503 case. I couldn't spot something wrong for
register that got 503. Next ones have two contact headers, but that is
fine in SIP.
Cheers,
Daniel
