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

I am trying to write a dialplan that will use Dial() to call two local
extensions. One extension will run an AGI script (a continuous background
process, running until hangup), the other will connect the active channel
to Jack() (also running as continuous process, until hangup).

This is my current dialplan attempt:

exten = 514316XXXX,1,Answer()
same => n,Playback(hello)
same => n,Dial(LOCAL/100 at extensions&LOCAL/101 at extensions)
exten => 100,1,JACK([i(SuperCollider:in_1), o(SuperCollider:out_1)])
same => n,Hangup()
exten => 101,1,AGI(test.py)

Currently, this will start my python script via AGI & run it as blocking,
stopping extension 100 from connecting.

I’ve also tried the following alternative syntax’s with Dial, with varying
results but no solution yet:

same => n,Dial(LOCAL/100 at extensions,,&LOCAL/101 at extensions
same => n,Dial(LOCAL/100 at extensions,,g&LOCAL/101 at extensions,,g)
same => n,Dial(LOCAL/100 at extensions,,G(extensions,101,1))

>From my readings of other related issues, I think I’m very close but have
just minimally messed up the syntax. I know trying to force two running
processes on the dialplan is not generally recommended, but I have a
specific use-case, and my Asterisk server will only be handling a small
number of concurrent callers.

I can provide more detail on my python script process, my need for Jack,
etc. My need for parallel running processes on the dialplan was spurned by
issues I’ve had with JACK_HOOK, which are detailed here:

Thanks in advance for any help or suggestions!
