v5.2.3 of Kamailio. Serial forking is used to route calls to a multiple
destinations as described in documentation for the TM module.
Also using the DIALOG module - my script calls dlg_manage() before loading
the serialised branches.
I need to be able to substitute the username part of the From header and
have been trying this with calls to uac_replace_from().
modparam("uac", "restore_mode", "auto")
modparam("uac", "restore_dlg", 1)
There is no problem if all branches use one substituted From username, in
which case my script calls uac_replace_from() in the main route.
uac_replace_from("sip:" + $avp(route:src) + "@" + $fd);
However, I may need to substitute a different value for each branch. Can
this be done?
I tried moving the call to uac_replace_from() into the branch route, but
then I get an error when the final BYE is received:
ERROR: uac [replace.c:281]: replace_uri(): decline FROM replacing in
sequential request in auto mode (has TO tag)
Is there a simple solution to this please? Hoping I can still use UAC auto
restore mode because manual restore looks quite tedious/complex.
Thanks.

Hi John,
Nevertheless, and despite the error on BYE (not immediately sure of the cause—do you have
rr:append_fromtag set?), calling uac_replace_from() in a branch_route is the correct
solution to the problem. It will cause the message changes wrought by ‘uac’ to be reverted
to the original message buffer, plus any permanent changes, upon the initiation of a new
branch attempt.

Hello,
the reason for writing the error message seems to be that you execute
the uac_replace_from() for requests within dialog (e.g., re-INVITE,
BYE). In auto-restore mode it has to be done only for the initial
request (first INVITE of the call), then the module does automatically
the changes for requests within the dialog and the responses.
You should add a condition like:
if(!has_totag()) { ... }
Cheers,
Daniel

Hi Daniel,
Thanks. I can see now what I have done. I'm using the same branch route for initial
requests and also for loose routed requests.
It either needs a test like the one you suggest or maybe use a different branch route for
loose routed requests.
