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.39>sip: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_replace_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.
