Can I setup my Pbxes to do the following:
1) Callback for a local mobile phone (in Canada).
Let’s say I have a cell phone with unlimited in-bound minutes. To request a call-back, I dial a local (or 800-number) DID, which I own. This DID points to the SIP address of the incoming trunk of my callback server. The callback server looks at the CID of incoming calls and if it matches my cell phone number, then it rings back to my cell phone. It is important that the ring-back call can be routed routed via a VoIP provider of my choice.
2) Callback for a remote international location.
The previous scheme is extended as follows. The request for call-back is sent as SIP-call at the SIP address of the incoming trunk of the callback server. When the callback server receives such a request, it matches the SIP address of the sender and, based on it, rings back to a PSTN number associated with the SIP address. Again, the ring-back call is routed via a VoIP provider of my choice.
Thanks.

A quick question for your scenario.
in your messagey you mentioned "your callback server", do you have such a server, or you are looking to implement this solution entirely on PBXes.
I do not have a server....Just now I realize that for one call-back I would need to use two out-bound channels
simultaneously...which will eat some of the savings
