[Asterisk-Users] RE: Caller ID

[Steve Underwood]

Wake up.

The reversal detection is a complete waste of time. Totally unnecessary. 
Pointless. A line break detector would have much more use, as it would 
give a reliable disconnect detection on many lines. (Actually, reversal 
detection would have years ago, but its not much use any more).

All you need for these CLI requirements is to monitor for some energy on 
the line. Since these FXOs are not being used in banks of hundreds, you 
will never notice this MIPs this uses.

Regards,
Steve
