Hi guys, my first time here, and thanks for this great forum where members can help out each other!
I just need some explanation on how the PSTN to Asterisk communication works. I have an Asterisk system connected to the outside world (PSTN) using an E1-line. I use a dual-span Digium card where only one span is connected to this E1-line through a modem. As I understood this far, I can receive 30 concurrent calls to the Asterisk system from clients through the PSTN.
Here comes my doubts: What happens if there are more than 30 clients calling my DID simultaneously? Will the telco forward them to the Asterisk system anyway, or will clients just get busy tones? The intention is to keep those who are not directly connected when dialing my DID in a queue until there are channels free to connect them. Is there any chance?
