[Asterisk-Users] Asterisk and Credit Card Machines

[Chris Coulthurst]

I am planning to deploy an Asterisk server at a local restaurant and was
thinking:  I hear a lot of troubles using fax machines with IP trunks.
What about using Credit Card readers?  Same basic technology right?  A
slow modem to negotiate the transaction.  Does anyone have any caveats?
Suggestions? 

Incidentally, the credit cards might be on POTS lines with a Digium
TDM22B.  Any concerns using this arrangement?
