Hi Max,
Some operators (e.g. Orange in the UK) will allow you to have two
numbers attached to one SIM, which might get you 4/10ths of the way to
your goal.
I'm struggling to see why purchasing DIDs won't help, unless your FS box
has no internet connectivity. A bit more background on the problem
might help with finding a solution?

Pleas help me answer the following question. Sorry for being a bit
off-topic. I have a GSM-VoiP modem with just 4 SIM Cards. Is there a
known mechanism that allows me to use this modem for more than 4
(albeit not at the same time) GSM numbers? Let's say the phone
numbers of the SIM cards inserted in the modem are call real phone
numbers. My goal is to have some 10 additional virtual phone numbers
served by this very same modem.
One way i thought this could be done is by forwarding the virtual
phone numbers the 4 real phone numbers. Then, when somebody calls one
of the virtual numbers, the Telco will forward it to the real phone
number and it will end on Freeswitch box. My only problem is now that
on the Freeswitch box I have no idea what virtual phone number was
actually dialed. Any idea how to recover this phone number? I looked
at the GSM specification and couldn't find a way.
PS. Purchasing DIDs won't solve my underlying problem.
Thanks,
Max.
