<TITLE>Unable to register CME with VOIP Carrier</TITLE>
</HEAD>
<BODY>
<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I have the following topology:<BR>
<BR>
Internet — 2651 — Switch — 2651XM<BR>
<BR>
The 2651 is acting as a gateway running NAT for my Comcast internet line. The 2651XM is running CME. I am trying to establish connectivity with my Voip carrier but they are claiming that 1) You are sending a phone number as your username and 2) You are sending an internal IP in the Via header which is why the registration is failing.<BR>
<BR>
How can I configure CME to send the username and not the phone number for the registration along with setting the IP public IP address (which is the IP on f0/0 on the 2651) on the Via header?<BR>
<BR>
Below is a debug of the REGISTER and Received messages along with my sip-ua configuration.<BR>
