Can these GSM modules work as proxies so when you are local your GSM
handset can be used on the VoIP network?  When you walk away from the
nanocell/picocell transmitter it autoswitches to the real provider.

The way GSM auth works this technically would not be that difficult to
do, and infact there is equipment that does not interface to anything
that does proxy call setup/tear down info (IMSI catchers for example),
so what I am asking for is not that far out.

This would also make it easier for call shops, set up one of these and
people can use their mobile as a voip phone.  In the office your GSM
calls are sent to asterisk to your desk phone and/or your mobile,
outbound calls go over asterisk for least cost routing, etc.  But the
handset is your mobile (and in theory on your person at all times).

If anyone knows of a device that integrates to asterisk that does that I
would *greatly* appreciate hearing from you regarding a vendor,
make/model, even a supplier.  If you are a supplier I grant you
permission to use my contact info to directly contact me about that
issue only so long as you dont add me to any lists.

Thanks
