Install OpenVox asterisk GSM card- G400P

Hi,
I'm using G400P with Elastix and have problem setting up incomming routing because G400P doesn't send DID so I can't route incomming call to anywhere (except for all-catching). Is there any workaround? I found this: http://www.freepbx.org/support/documentation/howtos/how-to-get-the-did-of-a-sip-trunk-when-the-provider-doesnt-send-it-and-#comment-57873 but I'm using "custom" trunk so I can't enter any peer details.

Thx in advance.

Thanks for that - and I may have the answer. As we don't want to take incoming calls on the cellular line (the circuit was put in in order to make outbound calls less expensive, not to make inbound calls more expensive!), I didn't bother setting up an inbound route as we didn't want it to be used that way.

I've now setup an inbound route with an instruction to drop the call and, so far, the card has stayed up for twelve hours. Will test again in the morning...
