How easy is it to configure multiple devices (provided ATA along with a sip phone or softphone) to work together on the same nat-ed network? I await my adapter and sip credentials, and will need to connect the ata either behind my existing router/modem combo unit (Uverse) as a nat-ed or dmz-ed device, which I gather works OK...but question is can I additionallly use a byod device...that will allow ring, callout, answer successfully on same network (same number too)? If I have set udp range destined for the ata, how do I get this traffic alternatively to the sip phone at another ip?

Maybe I'm over-thinking this, as it appears others have it working?
