I've scanned through a number of posts here and elsewhere, but I'm still looking for a definitive answer about whether and under what conditions the PhoneGnome will accept an inbound SIP call from other devices.

The PhoneGnome looks handy for getting non-technical users (i.e. relatives in other locations) up and running with a minimum of fuss.

However, I'm already dealing with several Asterisk servers sitting in different sites and would like to preserve the ability to make direct IP-to-IP calls to known devices.

On a related note, did anyone find out if the PhoneGnome firmware upgrade for the SPA-3000 can be reversed?

I haven't tried doing IP-to-IP calling with Phone Gnome, but I know that if you try calling Free World Dialup to PhoneGnome, it doesn't work (you get some kind of recording advertising PhoneGnome). It'd be nice to offer bidirectional calling between PhoneGnome and other SIP networks, as well as IP-to-IP calling (though that's a bit more difficult).

The SPA-3000s sold by PhoneGnome have different defaults burned into their ROM which cannot be reversed by a factory reset.

The FAQ http://www.phonegnome.com/faq_using.html#q13 discusses this:

PhoneGnome owners can call other SIP services via SIP address using the on-line phone book, or by prefixes for dialing FWD, SIPphone, and Earthlink.

Peering is also active on FWD and SIPphone (Earthlink coming soon) for alling to PhoneGnome. On FWD, dial **742 followed by the PhoneGnome owner

When I tried calling an FWD number from my PhoneGnome several weeks ago, the SIP URL the call came from was apparently not valid to call back. I wonder if that's considered a "bug" or not.
