Faced with such a problem.
We have a Asterisk (FreePBX) and GSM-gateway Dinstar DWG2000F.
Configure incoming line from SIM to queue.
- When an incoming call on the second line of the first cut off the conversation.
- Sometimes the call generally “stuck” in the PBX does not reach by telephone.
Who faced? Generally queue to Asterisk working with the second line on the SIM card?
