[OpenSIPS-Users] Dialog timeout_avp and onreply_route

[Mariana Arduini]

Hi Muhammad,

"Well, i think if you have enabled onreply_avp_mode in TM module then you
can access and change AVP you set in route block in on_reply block. I don't
see any reason why you need to modify opensips source code for this."
Yes, I have that enabled in tm module, and in fact I can change avp values
in onreply_route, from what I see in other avps we use.

The problem is that it seems the dialog module cannot apply the new avp
value to the dialog timeout. Check dialog module docs:

http://www.opensips.org/html/docs/modules/devel/dialog.html#timeout-avp-id

** It may be used only in a request (initial or sequential) context**

Using opensipsctl fifo dlg_list, I can see that the timeout value is set to
43200 seconds, which is the dafault value, even after setting the timeout
avp in onreply_route:

# opensipsctl fifo dlg_list
dialog::  hash=1571:444747590
state:: 4
user_flags:: 0
timestart:: 1352912021
 timeout:: 1352955222
callid:: 1-8696 at 91.190.218.180
from_uri:: sip:daitan.engg1 at connect-lync.connect.com
 to_uri:: sip:lync_user at lync.com
caller_tag:: uac191.190.218.180
 caller_contact:: sip:10.22.136.172;transport=tcp;did=326.53fb7ac1
callee_cseq:: 0
caller_route_set::
 caller_bind_addr:: tcp:10.22.137.64:5060
callee_tag:: uas291.190.218.170
 callee_contact:: sip:10.22.136.170;transport=tcp;did=326.7efc7653
caller_cseq:: 1
callee_route_set::
 callee_bind_addr:: tcp:10.22.137.25:5060

I understand the dialog module won´t apply any change in the avp from
onreply_route, doesn´t matter if done manually or through SST module... =/

Thanks again!
Mariana.
