[Asterisk-Users] Ringdown Circuit Configuration

[Eric Wieling]

For Cisco IOS products you can use "connection plar opx <number to
dial>" and then set up a dial-peer for that number to go
wherever you want it to.  Plar is of course, Private Line Auto
Ringdown.  There are various examples on the Cisco web site.
