Re: [Users] Re: help: anonymous call

29 Dec 2005


      Hi,
first I think the if branches should be swapped - if the from URI has an 
username, then you should change it.
about how to use uac module for from changing:
    1) set to Auto the restore mode
          modparam("uac","from_restore_mode","auto")
    2) call uac_replace_from() only for initial request (without TO tag)
regards,

I am modifying features-callfwd.5.0.cfg from the getting start script.
I have inserted the following code after if (msg:len>max_len) {}.  It
is used to detect the @ in the from header to find any anonymous call
and replace that header to anonymous@calling_source.  I have no idea
it is the right way to do as there is an error shown in the log.  Any
comment.
   if (method=="INVITE"||method=="ACK"||method=="CANCEL"||method=="BYE") {
     if (from_uri=~".*@.*") {
       xlog("L_INFO","SIP  have @\n");
     } else {
       xlog("L_INFO","SIP  no @\n");
       uac_replace_from("anonymous","anonymous@$si");
     };
   };


In the log, below error shown.
