Please contact me directly,so that i can check your issues remotly.
My contact info be shown as below:
Yes, I am aware that this feature is present in the gateway itself. But if I use it, the PBX billing system won't be able to distinguish whether the calls were made through GSM or SIP, that's why I need to configure that in the Asterisk system that connects to the GMS gateway as a SIP peer, so that it could make a proper record to the billing data. So, the question is: does the gateway provide the necessary information (and what kind of information) to the Asterisk on the PBX, that connects to the gateway as a SIP client?
Finally, I managed to configure it.
But one question remains. If I save SIP Endpoint settings, a line "insecure=invite,port' appears in the corresponding section of sip_endpoints.conf. But I don't need it. Can you tell me how to turn it off?
