[Asterisk-Users] Analog modems behind an Asterisk server?

[Christian Schnell]

Hello, we would like to hook up analog modems behind an Asterisk server, 
and we're very interested in the experiences that others have made when 
attempting that. We assume that there are no inherent problems with 
modems in respect to the Asterisk software, but it appears that the 
FXO/FXS hardware restricts this kind of a setup to lower data 
transmission rates, is this correct?

Currently, we only transmit at 1200bps, is this rate problematic with 
Digium cards? Up to what data transmission rate are Digium cards known 
to work reliable? We do not think we'll ever go beyond 9600bps, can we 
do this with a let's say TDM400P?

Will future Digium hardware improve the situation or will this stay the 
same in the future?

How is hardware from other vendors performing when using analog modems?

Thanks for any information on this,
Christian Schnell.
