New subject: modify FROM field in the "failure_route" block

23 Mar 2012

      I am going to have to go with the "upgrade" crowd in this one. Running OpenSER 1.3 at this point is like running a libc5-based Linux distro.  Almost no advice or discussion is relevant to it because there have been such tectonic, generational shifts since.

Please upgrade to latest stable and try again....
Why? If you have to ask it, than you didn't got it...
new version === new functionalities
99% of list support and tips are based on last stable version. 1.3 is 
pretty old...

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
