Guys,

I have a customer that heavily uses modems, the problem they don’t work reliably with some of the carriers I have used like Level3. This is somewhat expected due to the limits in VoIP so I need a better solution.

If I set up an asterisk system on customer premise with an FXS card in it and have calls sent to another asterisk box with a PRI can I get this to be more reliable and better connect speeds.?
Any way to detect a modem call and turn off the echo canceller?

What if I use a lossless codec between the two systems, or would it be better to just run PCM to passthrough to the PRI.

Any ideas would be helpful.

Thanks
