What are you trying to do?   The only purpose / function of an ATA device is to obtain an analog dial tone on an internet VOIP line (SIP). 

What type of lines do you have and what are you trying to accomplish?

Was there a question in there?  I can tell you that modem over voip will probably not work well or at all. Maybe low speeds like 2400 or 9600 baud, but I would not have high expectations.  You may need a traditional landline for dialup to PcAnywhere.

Thanks for the comments.  I assume it is not going to work either as i have read as such -- plus with my testing, i cannot make it work.  I am just now testing Ringcentral for my phone system and my adviser suggested i post this topic here and walked me through it.  For more info... some of our customers do not have internet and we have to support them via dialup with desktop modems on each end and using PCAnywhere (an older product).

Yep.  I would try to see if you can force g.711 codec, I think that would be your best chance to get it working, but if you have to support many customer this way you might just have to go for a landline.
