[Asterisk-Users] faxing

[Deon Rodden]

We have at least 3 customers with Cisco ATA186's plugged into a fax machine.
They can send and receive faxes perfectly. The config in Asterisk is no
different than any other ATA186. G711Ulaw is the codec we use.

Supposedly the Sipura SP-2000 we're now using can do faxes as well.  Haven't
tested it yet.
