[asterisk-users] Credit Card processing machines

[Don E. Wisdom]

The ADT alarm going thru VoIP will create a life safety issue.  Hope you planned for that..

The client's processor charges 7c/transaction over IP (plus normal
charges), so they are quite keen to keep it working the way it was before
I replaced their PBX ;)

As a followup, *99 prepended on any Linksys ATA does indeed make a
difference in modem reliability.  Both their CCs and their ADT alarm
devices now function reliably.  I also reduced the CC baud rate to 300
baud (!), and it is rock solid now!
