[OpenSIPS-Users] ws and hold problem

[Alexander Jankowsky]

Hello Mikhail,

What exactly have you got there. It looks like a closed test setup.
Is it just Three routers in an upstream loop and Three computers.

Are you just trying to make some basic voip audio only phone calls.
Is there a more specific project you are trying to have help develop. 

I am not familiar with these other technologies
but it somehow seems you have not provided enough information.

Alex

Hi

opensips 2.4 and rtpengine.
webrtc SIP clients based on jsSIP 3.3.6
to accounts jssip1 and jssip2

jssip1 calls jssip2 or jssip2 calls jssip1 - call established
jssip1 place call on hold and then unhold - no problem now if jssip2 place call on hold it receives SIP/2.0 476 Unresolvable destination (476/TM) from opensips and call brakes.
also in opensips.log there are a messages like this:
May 25 02:42:41 opensips-01 /usr/sbin/opensips[19704]: 
CRITICAL:core:mk_proxy: could not resolve hostname: "djgppiddv7t0.invalid"
May 25 02:42:41 opensips-01 /usr/sbin/opensips[19704]: 
ERROR:tm:uri2proxy: bad host name in URI <sip:lp7tmvt6 at djgppiddv7t0.invalid;transport=ws;ob>
May 25 02:42:41 opensips-01 /usr/sbin/opensips[19704]: 
ERROR:tm:t_forward_nonack: failure to add branches

what i found:

While call setup jsip1 sends initial invite:
INVITE sip:jsip2 at 192.168.18.78 SIP/2.0
Contact: <sip:lp7tmvt6 at djgppiddv7t0.invalid;transport=ws;ob>

server resends  to jsip2 invite and replaces Contact with the real ip of
jsip1:
INVITE sip:60s8k9ep at 192.168.21.117:49882;transport=ws SIP/2.0
Contact: <sip:lp7tmvt6 at 10.20.32.10:46099;transport=ws;ob>


When jssip1 place call on hold or unhold, it sends invite to server with
INVITE sip:60s8k9ep at 192.168.21.117:51630;transport=ws SIP/2.0
Contact: <sip:lp7tmvt6 at djgppiddv7t0.invalid;transport=ws;ob>

server resends  to jsip2 invite and do not changes Contact:
INVITE sip:60s8k9ep at 192.168.21.117:51630;transport=ws SIP/2.0
Contact: <sip:lp7tmvt6 at djgppiddv7t0.invalid;transport=ws;ob>

Next, when jssip2 places call on hold, it sends invite:
INVITE sip:lp7tmvt6 at djgppiddv7t0.invalid;transport=ws;ob SIP/2.0
and server can't resolve djgppiddv7t0.invalid, it expects real address here


does anybody have an idea, who is responsible for the problem - jssip, 
opensips or rtpengine ?


Laba Mikhail
