I'm looking for some help configuring a voip.ms incoming trunk line with CUCM 7.0.1 . Outgoing is working fine. Screenshots of the config are attached. Voip.ms allows static authentication, and I see the packets coming into the server which is not behind a nat, but I'm getting a busy tone.
I think I configured everything I need, hopefully properly, so any insight would be greatly appreciated. I tried to take screenshots of everything I did, so its likely that if its not attached I didn't config.
One thing I noticed that I can't figure out is that when you are calling extension to extension is that the phone you are calling the user's name appears on the calling phone, but the extension name shows on the destination phone. The two phones are set up the same aside from the ext #s.
Thanks in advance.
