[Freeswitch-users] [Out of curiosity] Why not use a voice modem for FXO?

[GillesToo]

Most X100P clones don't use any kind of Silicon Labs chip. Whatever chip they
do use will probably not be programmed properly to match the line, because
the drivers don't support that. However, with the use of a decent echo
canceller you'll probably never notice. Use OSLEC with most X100P cards on
most lines around the world and the results should be pretty good.

Thanks for the clarification. I have a bunch of X10xP cards, and they all
have chips that say "Si". Unfortunately, the ones that have the supposedly
Europe-compatible chip (3014 + 3021)... I couldn't get to work on the
computers I have here. I guess it's a hardware issue.

Too bad no one followed the X10xP project and came up with a reliable,
entry-level card for SOHO users. $100 is almost the price of the PC on which
Freeswitch is running :-)

Thanks for the technical infos.
