If I understand SIP, it’s possible (often simple) to have multiple connections through one client/account. Like instant messaging, you can chat with more than one person at a time.
Does Asterisk support multiple connections on a single SIP channel?
to clarify, if I’m currently on a call using my FWD account SIP Channel, and someone calls me on that account, will asterisk answer and route to other extensions/ voicemail? or will the Channel just pass a busy signal?
I’m having difficulty testing it right now, and can’t tell either way.
