Before i’m sorry for my english my first language is French
please i have a issue using asterisk with a GSM gateway.
I use asterisk with a GSM gateway DINSTAR DWG2000F to make IP calls to GSM as part of the establishment of a call center. I set up an IVR on asterisk that works great when IP calls to IP. without the IVR the IP to GSM and GSM to IP calls work perfectly well. but by integrating the IVR, during incoming calls (GSM to IP) if the caller chooses the option to talk with an operator, the caller is put on hold and the operator’s softphone starts ringing; when the operator picks up, the caller is still waiting and neither end hears the other: no conversation is possible.
please help me to see more clearly.
when i scan the communication between the GSM Gateway and asterisk with wireshark, i can see a reINVITE packet send by asterisk to the GSM Gateway. i think that why the caller is put on hold.
i try to enable this directive in sip.conf file but nothing i have the error.
i think it’s my asterisk the issue…
Please an idea, a track, …
