Most fairly new modems should be compatible with AudioTX POTS.
We have tested PCI, PCMCIA, ISA and USB modems with success in almost
every case. We have also found that some external serial port modems
also work, though we would not recommend these as a first choice.
SoftModems (known as WinModems) do sometimes cause a problem and
so not all of these will work. These special modems rely on the
computer to do the work for them and are less reliable for audio
transmission than a standard hardware modem. We suggest that you
Here are some other useful pointers:
- Your modem should be capable of at least 33kbps
connections to get good audio quality... most new modems are 56k
or even use the new V.92 standard, so this shouldn't be an issue
unless you have a really old one!
- Your modem should provide good reliable connections
- for example, if you use it for connecting to the internet, does
it drop connections, or does the connection freeze from time to
time? If so, it will do exactly the same with POTS!
