[asterisk-users] pci cards VS patton

[Giorgio Incantalupo]

Hi all,

I've been using telephone cards for 4-5 years and now I'm considering 
the Patton gateways. What are the pro and cons of Patton stuff compared 
to internal cards in a production system? Someone say external gateway 
are better because has no echo but have a longer delay when placing calls.
Any suggestion appreciated.

Thank you!

Giorgio
