[Asterisk-Users] PSTN to VoIP

[Paul Crick]

The Sipura's work really well and are highly configurable.

If you just want to connect a regular POTS device via VoIP the SPA-1000
will do the trick. The 2000 has 2 ports instead of 1, for a
less-than-double increase in price. The SPA-3000 has one FXS port but also
has an FXO port so you can connect a phone line to it too, as well as a
regular POTS device. Could be handy for analog connectivity?
