I'm saying AFAIK they don't support any endpoints other than those they 
sanction registering in the first place. Maybe you can fake them into 
believing your device is legit, but probably they are trying to prevent 
you from that.

In case of Comcast, I'm assuming you mean Comcast voice service. 
Actually, I believe that isn't even SIP - its MGCP for the phones. Or if 
you mean the comcast network service, then I don't think it will provide 
any sip emergency services.
