Um, no VOIP involved here.
Wrong. What do you think Asterisk is? Chopped meat? It's a VoIP
switch. All traffic inside Asterisk is VoIP.
I have an asterisk server with 2 23B+D PRI's
I want to telnet/ssh into the asterisk server, and make an outbound call
serial based modem/terminal connection (Like the 80/90's BBS Days).
No TCP/IP or PPP or crazyness
(ie, dialing into a Modem set to AA hooked to a Cisco Console Port)

One of my tech had an idea of using IAXmodem or something similar to
use
existing PRI/DAHDI Trucks for dial out via the asterisk/Linux
console.
Anybody ever heard of doing this?
I would think maybe would use iaxmodem maybe and a shell terminal
app?
(basically I'm dialing into a remote access device that uses a pots
like
for remote administration, and don't want to string a channel bank
off
my asterisk box, and a hook to a modem)

Depends on your expectation. Because of compression in the codecs, it
will be hard to get fast dialup. If you mean ssh or telnet, it might
work. If you mean vnc or RDP over this, you may not get enough usable
bandwidth to do that.
Given this, I have in an emergency dialed into a RAS server via a VoIP
line. My laptop connected at 14,400bps. All I needed to do was telnet
into an APC masterswitch to toggle power on one outlet. It worked.
I was surprised at getting a 14,400bps connect. I was not expecting
that high and really did not need that high. 300 baud probably would
have been fast enough to telnet into an APC masterswitch.
