Ok,
>From the uac documentation I can see I can only use it once, but even
modifying the TO header on the first routine (Dispatch) somehow different
(subst, subst_hf, $td=$rd..) the outcome is the same, strange TO mixed.
If I cannot modify TO twice, how can I made it equal to the RURI domain in
direct routing and in case of failure?
Thanks...
Helena

Hi Carsten,
I am sorry, I am not sure if I am understanding you correctly. Thank you
very much for all the tips.
I still have the same problem, the second time I try to manipulate the TO it
appends the new value instead of substitute it.
My code is at the end (bit different because it is now on a different test
environment).
When gw 1(X.X.X.102) is not responding to INVITEs, after the timer the
server send the new request to gw2(X.X.X.180), set RURI fine but the TO has
strange format (not correct) It is appending the new value to the value set
on the DISPATCH route
To: SET_TO <sip:XXXXX69 at X.X.X.102SET_TO <sip:XXXXXX69 at X.X.X.180>>
The problem is only when I do it twice (on distich routine and on
branch/failure). If I don't touch the TO on the DISPATCH routine, then the
uac function on the branch works fine. The problem is that I need that the
TO is equal to the RURI on both cases!
Thanks again, Could you tell me if that was not what you meant? Or if I am
not using the function properly?

Hi Helena,
Just a quick note:
If you do a failover from failure_route(), this will also create a new
branch and the branch_route() would be executed, too.
Kind regards,
Carsten
