goog411 has been around for a little while now. however, that is a great idea using it with the phone system. with your dialing outbound rule, i think we could accomplish the same thing by just prepending prefix 411 with 8004664. Also, make sure you don't have an extension 411 in your system.
So,
Rule Name: GOOG411
Calls to Numbers starting with (Prefix): 411
Calls to Numbers with a length of: 3
Route 1: (Outgoing Line)
Strip Digits: 0
Prepend: 8004664
It may be necessary to add a 1 before 800 depending on your provider. I tested this rule and it works fine.
08:11:54.643 CallCtrl:nSelectRouteReq [CM503004]: Call(50): Calling: PSTNline:8004664411@(Ln.10001@0244)@[Dev:sip:[email protected]:5062]
08:11:54.342 CallCtrl:nIncomingCall [CM503001]: Call(50): Incoming call from Ext.107 to [sip:[email protected]]
I didn't have a problem... but this is being "advertised" on their front page, so maybe they are getting slammed as every PBX, Voip provider and end user is slamming it.
