Hi,
did you install it from source? If yes, you can simply add the "BRANCH_ROUTE" to allowed routes in OpenSER 1.3, that should work, i used it that way many years ago... (i think you need to change the module another place too). I strongly recommend you update your OpenSER to a more recent Kamailio, then you won't have that problem at all.
Kind regards, Carsten

Hi,
Even though when I try to use "uac_replace_from( )" in branch_route block I get the same error message:
branch_route[2] { if ( $avp(i:204) ) { uac_replace_from("hello"); }
}
error message:
Not starting openser: invalid configuration file! Mar 23 09:03:00 [7542] CRITICAL:core:yyerror: parse error in config file, line 623, column 26-27: Command cannot be used in the block Mar 23 09:03:00 [7542] ERROR:core:main: bad config file (1 errors)
PS: I am running an old release of openser 1.3.
Thanks, R

You can probably get around it this way:
failure_route[1] { ...
append_branch();
route(STUFF); t_relay(); }
route[STUFF] { uac_replace_from(...); }
indeed this should work -- it is no reason of not being usable in failure_route, perhaps is so from the time of development. The function itself is allowed in branch_route which is called from inside t_relay() (when t_on_branch(...) is used), therefore we can relax the restriction for failure_route, imo.
One thing to take care of, if you use uac_replace_from() in request route and then in failure route, you may end in malformed format, so it is recommended to use it in branch_route, then the changes done by the function will be per each forwarded branch.
Cheers, Daniel
