David,

Thanks for the post.  can you elaborate on "

Known Issues:

     * PSTN phone  did not disconnect  when extension phone init disconnection."

Is this fixed?  Is this a Cisco issue?

Thanks,

John

I tried the above configuration and it did not work so I tried other configurations based on the settings in my CBeyond (former Aretta account) as follows and it successfully registered and passed calls back and forth even though I have dynamic public IP. Perhaps the difference between this setup and the one above is that SIP CBeyond my account was originally setup when CBeyond was Aretta Communications and the URL has always been and still remains sip.aretta.net which may be why this worked for me but I don't know if the above settings is what newer Cbeyond customers who signed up directly with CBeyond after they acquired Aretta Communications. Pick what works in your case, I guess.;
