No, when you make a call from a SIM the phone network only sees the SIM's phone number. You can either send that or withhold it, but not send the other leg's caller id.

Are any of these GSM Gateways capable of passing the original caller's ID?

Thanks
 

A more premium solution would be 2N at http://www.2n.cz/en/
These work very well and in my experience are reliable.

Portech also have external boxes:

Haven't used them myself but someone in #freenode once mentioned
Mobigator, a GSM gateway compatible with FreeSWITCH. Uses a simple USB
link to hook up to your freeswitch server. On the software side I think
you need to install gsmopen on your FreeSWITCH box (howto on wiki).

At about $120 or €90 they are quite affordable but I don't know how well
they work.
