triggering a callback without Obi answering the call

What services do you have set up on your OBi? Which country SIM(s) do you have? In which countries will you be traveling?
I have two Obis (100 and 110) currently located in the US. I have GV setup
on the 100 where SP1 is the GV service and SP2 is occupied to forward GV calls to a Grandstream IP phone.
The 2n Obi which is an 110 is in front of a Vonage adapter (which is my default family line). I have setup
easyvoip and voipalot on the SP1 and Sp2 services of the 110 respectively.
In the next few months I will install also one in Greece which I intent to use also for some
local mobile-to-mobile calls (through callback) so that calls are not backhauled back to my USA obi.
My calling needs are mostly in Greece and India at this stage (yes I know that India is not Europe.. was trying to keep the example cases limited).
In Greece I do have a SIM that I renew on each travel (so effectively I maintain the same phone #).
In India I get a new SIM every time I land there. Also occassionally I need similar service in
France and UK.

I'm asking this, because there are probably ways to set up the OBi to have two or more callback choices, using local numbers dialed from the EU mobile. I live part time in France and use a prepaid phone there. My OBi is set up so I can dial one Paris number and get a callback via Voxbeam, or dial a different Paris number and get a callback via Orange.
Can you please elaborate on this? I don't see how the Obi is in the call path.
Also: after seeing some of your posts I checked a bit Voxbeam. Do they offer their service
retail to individuals? or they mostly do wholesaling to companies/businesses. They do
have fairly aggressive pricing and if the do offer service to individuals I'm willing
to setup an account with them as well.

There are also commercial callback services (more expensive than using the OBi, but still fairly reasonable) that can serve as a backup. Take a look at Fonworld and Future-Nine.
Thanks. Will do.

You may want to look at LocalPhone.com (a Voxbeam company) as rates are pretty good also. They will give you a UK# for free.

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.

@lhm: thanks. Will keep that in mind.
@Stewart: thank for the detailed description. I got the idea.
What I didn't pay much attention to (even though I did come across
some posting) that were mentioning that some of the SIP services don't need
registration). This is actually very powerfull as I thought I couldn't use
my Obi100 (which had both ports occupied) to return my call back.
With that said, I'll take a look to see how I define such VG.

lk96:
after some more thinking on Stewart's response and advice, I'm trying to figure out the following:
Consider my case where both SP1 and SP2 of my Obi100 are used/occupied for GV and bridging GV calls
to an IP phone. As per Stewart's response, I can configure a VG to be the one
to be used by the AA to call me back through a SIP service that doesn't require
registration. So far so good.
Once I get the call back at the mobile phone, I will be on the Obi AA prompt. At that point
I will have to dial the destination number I desire to reach. How can I instruct the Obi
to use a VG or a trunk *other* than the SP1 and SP2 to dial out the destination number ?
I thought as a workaround that I could pre-program some speed dials.
But upon checking the admin guide it seems
that a speed dial cannot be a VG (only SP1, SP2, LINE and PP are allowed).
Any ideas how this can work ?
thanks
