Quote from: lk96 on January 14, 2012, 07:58:11 AMCan you please elaborate on this? I don't see how the Obi is in the call path.
I live part time in Paris and have an OBi there. It's configured with an Orange pseudo-POTS line (like your Vonage) on the LINE port, PBXes (sub-PBX) on SP1, Phonepower on SP2 and Voxbeam on VG1. For example, my prepaid mobile in France is 0612345678.
InboundCallRoute for the LINE port is: {(xx.612345678):aa(**80612345678)}, ...
So when I call the Orange number from my mobile, I hang up before the AA answers and it calls me back, using the LINE port, i.e. Orange.
InboundCallRoute for SP1 is: {(<**30011101>(33612345678)):aa($1)}, ...
I have a PBXes trunk registered to
ippi.fr, with a free Paris number. When I call the ippi number from my mobile, I hang up before the AA answers and it calls me back, using Voxbeam and adding the Premium prefix.
Once I answer the callback, I can dial 2, then call out through any of the configured services.
Although my setup uses local numbers, you could use any DIDs anywhere in the world, as long as your mobile carrier doesn't charge you for an unanswered international call (and if that's a problem, see below workaround using Localphone). For example, you could route a free IPKall DID to your OBi110 SP1 and another to SP2. Calling one DID might trigger an Easyvoip callback and the other a Voipalot callback.
Both Easyvoip and Voipalot will accept unregistered (but authenticated) calls, so you can put them on a VGx and use the SPx for something else, e.g. Callcentric or Localphone, who provide free iNum DIDs. Then, you can set up a Localphone or Rebtel account to ring the iNum when you call an access number in your current country. Calls through Rebtel modify the caller ID; you can set the OBi to recognize the modified number and take a different action.
Voxbeam is the Costco or Sam's Club of wholesale VoIP, with lots of small customers. You get a $1 credit at startup, which is enough for lots of testing. Then, the minimum payment is $50, which expires after one year, implying minimum usage of $4+ per month. There is a 2.5% surcharge for credit card or Paypal payments, but you can pay by ACH to avoid that, if you have electronic bill payment with your bank, broker, credit union, etc. Also, they authenticate by IP only; if yours changes frequently, I can post a script that updates the site automatically. You might also look at FlowRoute, with slightly higher rates but fewer gotchas.
