[asterisk-users] Parallel dialing / running dialplan process in background

[Dovid Bender]

Asterisk will try calling both at once. As soon as one is answered it
cancels the call to the other. What you can do is for extension 101 to put
it in it's own context and then call the agi from the h extension. So
something like this:
[from-internal]
exten = 514316XXXX,1,Answer()
same => n,Playback(hello)
same => n,Dial(LOCAL/100 at extensions&LOCAL/101 at extensions)
[extensions]
exten => 100,1,JACK([i(SuperCollider:in_1), o(SuperCollider:out_1)])
same => n,Hangup()
[our_agi]
Exten => 101,1,Congestion
Exten => h,1,AGI(test.py)
