[Serusers] 0.8.12 appears to match URI against INVITE line

[Jamin W. Collins]

It would appear that SER v0.8.12 is performing URI matching against the
INVITE line rather than the To: header.  This appears to cause problems
with Snom phones.  Below is the initial INVITE request sent by a Snom
200:

  INVITE sip:172.21.30.53 SIP/2.0..Via: SIP/2.0/UDP 172.21.20.89:5060;branch=

  15..a=sendrecv..

The SER configuration has the following directive:

        if (uri=~"^sip:580[0-9][0-9][0-9][0-9]@") {
                log(1, "Local call sent to gateway");
                rewritehost("172.21.30.51");
                t_relay();
                break;
        };

This fails to match the above request even though the To: header in the
above request contains the necessary pattern.  This same configuration
works fine with a Cisco phone, but it's INVITE request contains the a
complete URI:

Is there anything I can change in the ser.cfg to instruct SER to match
against the To: header?
