Sorry for resuming the post..
I can't understand how to handle failure messages after parallel forking. I
need a particular configuration or OpenSER must handle them the same way of
a single message?
I'm using OpenSER 1.2.3-tls and also using debug mode I can't see nothing
special.
Thanks.
Regards,
Antonio.

Hi all,
I have a Linksys SPA2102 with 2 phones configured with the same
account/number. If I call that number both phones ring and all is OK.
The problem is that if I set a call forwarding on one of the two line on
the SPA only one phone rings.
Openser receives the 302 message from the SPA but the failure route that
contains t_check_status("302") is not called.
The forwarding works if only one line is connected.
How can I handle the 302 in this situation?
Thanks in advance.
Regards,
Antonio.

Hi Antonio,
The problem is that you miss-understand the the parallel forking and the
failure route mechanism. Failure route is called only when the
transaction is completed and this means when all the branches are
completed. So, if one of your SPAs is sending 302, this will not hit
failure route as you still have the second branch still ringing. Only if
the second branch will fail too, the whole transaction will fail and the
failure route will be called.
For a better understanding, see:
http://www.voice-sistem.ro/downloads/2007.08.29-Admin-Course/
There is detailed explanation about openser routes.
Regards,
Bogdan

this reminds me hat figure 2.3 of OPENSER Devel Guide is misleading in
this regard. i understand that he figure is not an essential part of
the guide.

So can I intercept the 302 response in an onreply_route? I tryied to put the
below configuration taken from sipwise inside the onreply_route but some of
the used functions cannot be used in the onreply_route.
