Hi Carsten
Thanks for the info, but I cannot use a branch route, because it is a failure route, and I need to execute the dispatcher funcitonst to set the destination to proving and to select the next destination.
Does anyone know how to set the TO header to use always the same username and domain than the RURI, even on failures?
Thanks in advanced
Helena

Hi Helena,
we do it the following way:
In the main route: t_on_branch("some_route");
branch_route[some_route] { uac_replace_to(....); }
This way, the uac_* functions get executed for each branch individually.
Kind regards, Carsten

Hi,
Thanks for the tip, but I cannot manage it to work...
I hadn't uac module loaded, I loaded it and added
#MORODO TEST TO MODIFICATION loadmodule "uac.so" modparam("uac","restore_mode","none")
The uac function cannot be used on the failure rutine (it gives an error when restarting) so I chaged the order:
That is the default routing route[FROMPHONE] { [...] if(!ds_select_domain("1", "8")) { send_reply("404", "No destination"); exit; } t_on_failure("RTF_DISPATCH");
#MORODO Add profix to ISKRATEL: 0199 subst_uri('/^sip:(.*)/sip:0199\1/i'); # add prefix to URI uac_replace_to("","sip:0199$rU@$rd"); route(RELAY); exit;}
That is the failure function
failure_route[RTF_DISPATCH] { if (t_is_canceled()) { exit; }
#marking the gw as failed and set state proving, to send options ds_mark_dst("p"); # next DST - only for 500 or local timeout if (t_check_status("500") or (t_branch_timeout() and!t_branch_replied())) { if(ds_next_domain()) { t_on_failure("RTF_DISPATCH"); #in case of fail again it would try the next option
#MORODO, update IP on TO header subst_hf("To", "/(.*)@(.*)$/\1@$rd>/", "a"); route(RELAY); exit; } }}
But the result TO header is the same strange thing... mix of what it was on normal routine + what I wanted after the failure...
To: sip:0199XXXXX10@10.X.X.39sip:0199XXXXX10@10.X.X.38
It is like once the TO is modified, It does not modify it ok anymore...
Would you do it any other way that could be better?
Helena

I tried modifying again the TO header with: subst_hf("To", "/(.*)@(.*)$/\1@$rd>/", "a")
before the route(relay) on the failure routine, but it does not work properly, I am getting strange TO header like:
To: sip:0199XXXX@10.X.X.39 sip:XXXXXX@10.X.X.38
It looks like it is not parsing the to header it has before but adding a parsed version of the original header at the end of the other
one....
I tried with subst as well but the result is more or less the same.
Probably there is a better way to set the prefix and the correct IP on
the to header... I'll appreciate any help with this issue.
How about just using uac_replace_to()?
http://kamailio.org/docs/modules/stable/modules/uac.html#uac.f.uac_rep lace_t o%28display,uri%29
4.4. uac_replace_to(display,uri)
Replace in TO header the display name and the URI part.
display and URI parameters can include pseudo-variables.
This function can be used from REQUEST_ROUTE and from BRANCH_ROUTE.
