I can now dial using the domain name, not the ip and that part is working fine, I know it is dialing correctly now because it is using the correct ephemeral port ranges that the clients have registered with, and in addition I can see the packets show up at the Callee and they look good. Still no ringing, and all of my tests are done 3 times using inband, info, and rfc2833 for dtmfmode. For reference to these logs I should mention my Callee is currently at a static IP address, and is not being NAT’d (in the future this will not be the case and I have nat=no for that user=1111111111.) After viewing all the packets on both sides I can confirm that there is no NAT issues here, because neither client ever tries to establish a connection directly with any RFC1918 addresses, they always communicate back to the * Server.
Here is the sip debug output from a dial:
