Hello,
We are using a few carries where we are sending calls to, each of them is
using a special prefix in the From header in order to manage the callerid.
Some of them are not recognizing headers like P-Asserted-Identity or
Remote-Party-ID, so for them we have to replace the From header with the
corresponding prefix. The way we do - it's by using the uac_replace_from
function, which works fine.
The problem is when we are sending the same call to the failover trunk, and
that trunk is using a different prefix. We have to call again the
uac_replace_from function which is appending the new prefix to the existing
one, something like:
From: <sip:12345@domain.localsip:+12345@domain.local>;tag=as404cb50c
I was trying to use uac_restore_from() function and call again
uac_replace_from, but the result is the same.
Is there any way to call the uac_restore_from function twice for the same
call?
Thank you.

Calling t_save_lumps() before the changes are made and before t_relay()
might help, so that upon failure, Kam restores the SIP message to the
original state and then further apply desired changes.
Cheers,

Another option is to put the uac_replace_from() calls into a
branch_route, or a request-route subroutine that is called from a
branch_route. The lump changes will then be made on a per-branch basis
only and reverted on the next branch.

Indeed, calling this function from a branch_route works fine.
The only thing i noticed is the following messages in the log file:
*uac [replace.c:396]: replace_uri(): Already called uac_replace for this
dialoguac [replace.c:405]: replace_uri(): Deleted <_uac_tonew> var in
dialoguac [replace.c:396]: replace_uri(): Already called uac_replace for
this dialoguac [replace.c:405]: replace_uri(): Deleted <_uac_funew> var in
dialog*
As they are with INFO LogLevel - I'm just ignoring it for now.
Thank you Sergiu/Alex
