Hi Tzafrir, I don't know whether anyone has ever tried writing data modem drivers for the X100P. However, open source DSP's have limited access to patent and ip licenses and therefore in my experience only offer low end modulations (if I remember correctly, spandsp is limited to V.29 [9600bps]).

They were used in theZapata Telephony project, and later in Asterisk, as cheap FXO ("phone") adapters for the Asterisk PBX. Drivers for them, through the Zaptel framework has existed for quite a while (since 2002, I guess). I have a few of them at home at the computer I use as a PBX. While I now have a better adapter, I was wondering if I could use my X100P cards as modems to test my other adapter. BTW: another useful link: http://soft-switch.org/ (the spandsp library and libunicall). -- Tzafrir Cohen icq#16849755 jabber:tzafrir@xxxxxxxxxx +972-50-7952406 mailto:tzafrir.cohen@xxxxxxxxxx http://www.xorcom.com iax:guest@xxxxxxxxxxxxxxxx/tzafrir
