[asterisk-users] Asterisk to make multiple extensions simultaneous calls on a single telephone line

[Mojo with Horan & Company, LLC]

But he's talking about a single POTS line into a single FXO.  Only one 
conversation can occur across this link at a time.  The PSTN provider 
may send you special ring indications over that line to indicate which 
number was *dialed* to make it ring, but only one conversation at a 
time.  Generally, when one of your FXS phones is calling out on the POTS 
line, the other FXS phone will fail in its Dial statement and move along 
in the dialplan, probably indicating Congestion if you've configured 
nothing else.
