Quite possible this is the reason.

Is there a way to restart the connection without physically removing and reinserting the usb stick?

It seems something wrong with USB hardware. Maybe your USB port does not provide enough current for GSM-stick.

'bump'

Anyone get this issue or know what can cause it?

(moved from a different thread)

on occasion, when trying to make a call, we're getting 'NORMAL_CIRCUIT_CONGESTION' and we're not getting any incoming calls.

Currently what we do is unload mod_gsmopen, remove and reinsert the usb stick, then load mod_gsmopen. 

This also doesn't always help since sometimes we can't unload the gsmopen module (it says 'model in use'). in that case we restart freeswitch and reinsert the usb stick.

This might not be caused by the gsmopen, since we're controlling the messages coming from the sim, and we might be doing something wrong.

Anyone know what the issue is?

Thanks,

Shlomi
