In wrestling with Anveo Direct and Incredible PBX for Asterisk-GUI this weekend, we made an interesting discovery that perhaps some of you already knew.

Here's the Super Sunday, Ground Hog's Eve surprise...

If you have friends or business associates that use VoIP services with almost any of the leading SIP providers supported by Incredible PBX for Asterisk-GUI, you can call them for free by simply dialing their 10-digit number. You do not have to have any SIP or Google Voice trunks registered! This trick does not work with Google Voice numbers unfortunately because Bandwidth.com is blocking SIP on the GV trunks. But those that you call that have a registered DID with a SIP provider in the "Incredible 9" list will connect without a problem. Even after you've registered with other providers but not the one that your friend uses, you still can call them for free by dialing their number with the Incredible PBX prefix for their provider, not yours. You'll find the prefixes in the Nerd Vittles tutorial. Seems to be a gaping flaw in a few providers' Asterisk logic. :innocent:

NOTE: Some providers actually answer failed, unregistered call attempts rather than returning congestion. To maximize the free calling possibilities, we've now moved those providers to the bottom of the outbound-allroutes list in the latest release of Incredible PBX for Asterisk-GUI. Now they won't block otherwise free calls.

The easy way to test this is to invest a penny and actually install Incredible PBX for Asterisk-GUI. Configure no trunks with your credentials, i.e. a base install. It takes under 20 minutes on Digital Ocean.

Now register a SIP phone to your server and call someone you know (or yourself) that has a registered DID on another server with any of the Incredible PBX sip providers. A few don't work. Most do. Watch the Asterisk CLI to discover who the DID provider is as well as which providers are actually using someone else as their trunk supplier.

p.s. You can't be behind at NAT-based firewall/router or this won't work.

As long as you're on a roll please supply the directions for converting Lead to Gold....

I'm sure it can be worked out before the Super Bowl
