Thank you for your interest in FreeSWITCH. I can assure you that this
project is alive and well!

Firstly I would recommend that you check this page:

It describes the TDM abstraction library that FS uses to talk to various
telco cards like those from Digium, Sangoma, PIKA, etc. Most likely this
would be the place for you to start. You can also browse the code:

The best thing to do would be to hop on the IRC channels and talk to those
in the know:
irc.freenode.net, #freeswitch, #openzap, and #freeswitch-dev

MikeJ and anthm are the primary developers on this TDM abstraction layer but
there are others who also can probably give you some direction. Please
definitely review the OpenZAP information and then come join us on IRC for
some questions, as I'm sure you'll have many.
