[asterisk-users] * as VM for legacy PBX?

[Don Kelly]

Looks like you might be getting conflicting information.

The important thing is the * ports must be opposite what the PBX ports are.

Odds are, the ports on the PBX used for voice-mail are extension ports--they
look like central office lines (PSTN POTS), providing dial tone. The ports
on the voice mail server look like "stations" (telephones).

In * lingo, an FXO (Foreign eXchange Office) port CONNECTS TO an "Office"
port, so it LOOKS LIKE a "station."

an FXS (Foreign eXchange Station) port CONNECTS TO a "Station,", so it LOOKS
LIKE a "phone line."

When you do the test suggested earlier, plugging a phone into a port on the
PBX used for voice mail, you'll most likely get dial tone. When you attempt
to reach someone's voice mail through the PBX, the phone will ring. This
confirms that the PBX is acting like an "Office," so you want * to act like
a "Station." You would install FXO ports in the * system.

Wow.  Thanks for all the replies!  Something just occurred to me, though:
which side would be FXO, and which side would be FXS?  The PBX?  Or the
Asterisk/VM side?

Thanks again for all the info!
