[OpenSIPS-Users] Authentication problem with softphone X-Lite

[mmarzuola at interfree.it]

I want that all INVITE created by a local subscriber should be authenticated by my proxy.
I have installed more softphones in the same machine and the port number is automatically assigned (5060/5061/5062).
Sniffing the traffic I have realized that only some INVITE are authenticated.
By analyzing the headers of the INVITE not authenticated, I have noticed that the softphone X-Lite inserts in the From the number of port in addition to URI (sip:user at domain.com:port).
In the opensips.cfg the lines that allow authentication of these messages are in the main route:

if (!(method=="REGISTER") && from_uri==myself)
               {
               if (!proxy_authorize("", "subscriber")) {
                       proxy_challenge("", "0");
                       exit;
               }
               if (!check_from()) {
                      sl_send_reply("403","Forbidden auth ID");
                      exit;
               }

               consume_credentials();
                # caller authenticated
               }

Obviously the control "from_uri==myself" does not work for INVITE that have the from URI with the port number.
I tried to use the uac_replace_from(uri) function of the uac module to change the uri of the From by removing the port:

if(is_method("INVITE") && $(fu{s.select,2,:})!="") {
           $avp(s:fromURI)="sip:"+$(fu{s.select,1,:});
           uac_replace_from("$avp(s:fromURI)");
}

if (!(method=="REGISTER") && from_uri==myself) {
**
**
**

But in this way only the from uri of the INVITE ranging from proxy to an end-system have changed the uri while those departing from softphone remain unchanged.
Is a limitation of the uac module or I make a configuration error?		

I also tried to make the comparison between the avp variable created and myself, but I get the error syslog:

CRITICAL:core:comp_scriptvar: invalid operation 20/11
opensips-lab /usr/local/sbin/opensips[2655]: WARNING:core:do_action: error in expression (l=296)

I tried to replace == with =~ but I get a syntax error.
"myself" allow to make the comparison with a string or is there a way to make this comparison?

Thank you in advance.

Marzuola Matteo.
