Gizmo5 Offers Backdoor Dialing

Give the Gizmo5 team some credit for a catchy name for their new service called "Backdoor Dialing" that makes more calls free.

It appears what they are basically doing is connecting SIP numbers the same way others like Voxalot and JunctionNetworks are too making those calls that go to numbers which are Net connected free. This can be done using eNum directory look ups and a few other standards based routing registries like those from XConnect and Intelepeer..

I like it as it helps keep costs down.
