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
