[SR-Users] modify FROM field in the "failure_route" block

[Robert R]

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
