thanks for creating kamailio and good documentation for it.
Also thanks to Daniel for this guide
I managed to integrate kamailio with asterisk and a2billing and I do have
some small issues with some UA's.
Generally all soft phones are OK but from some I can not generate calls.
Especially it is true for Linksys SPA and Grandstream gxv3140. From 10
phones I have one with this issue, all config is the same on device side
and on server/config side, but some are failing to generate calls. These UA
will receive calls but will not be able to call. They are registered OK and
I see these devices as all other ones in location table. One work around I
have found is to update manually the cc_sip_buddy table(from asterisk
realtime) with IP address and port and big part of these US's will start
working. But still I have some that will not work even after that. What I
see when capturing with ngrep is this:
1) Invite with SDP
2) 407 Proxy Authentication Required
4) Invite with SDP
5) 100 trying -- your call is important to us
6) 401 Unauthorized
Not all captured calls have all 7 steps some of these drop at 4th step and
I mention that all UA-s are showing OK as registered.
I use sip.Server == "kamailio (4.1.6 (x86_64/linux))" ;
Please suggest some steps to increase that authentication time(i suspect
that these UA's do not have sufficient time to authenticate) and help me to
understand why this is happening.
Thank you in andvance.
