[asterisk-users] [Zaptel] Why no driver for PCI voice modems?

[Fred]

Hello

Considering how cheap PCI modems are compared to even the cheapest 
PCI hardware from Digium, OpenVox, Sangoma, etc.... I was wondering 
why Zaptel can't be used with those to connect an Asterisk server to 
a POTS line for low-level use? It just seems overkill for SOHO users 
who only get a few calls a day.

Is it because those modems are usually Windows-specific, and it would 
be too much work to have a working driver for Linux?

What about a Windows port of Asterisk and some glue to connect 
Asterisk to the modem driver?

Thank you.
