[VoiceOps] Analog Phone Lines - Timesouce for PBX System

[Paul Timmins]

A lot of older systems will set the clock from the incoming caller ID 
data - the time and date are in the stream of FSK along with the number 
and name. You'd want to make sure that ATA has valid time and timezones 
set, then send a call into them and the PBX should jump to the correct 
time and date
