Faxing

I have a customer that has 24 fax machines. We are trying to talk them into an Asterisk system using a digium T1 card and a 2400 series card for connecting to their fax machines. All their DID’s are on one single T1. Does anyone have any experiences using Asterisk in a high fax volume installation or installing a Digium 2400 series card in this type of environment?

Any help would be appreciated…Ken
