Clarification re sipura boxes


It’s my understanding that the sipura boxes allow me to attach normal phones to IP, but cannot be used to connect softphones to the PSTN. SO to get out via Asterisk I need a digium card in my Asterisk server.

Is this correct?


The Sipura SPA-1000/1001 and SPA-2000/2002 are only analog telephone adapters. They’ll let you put a plain ol’ telephone an in IP telephony network.

The SPA-3000, on the other hand, also has an FXO port which you can use for dialing out to the PSTN. A Digium card would be more flexible, but it is possible to use the SPA-3000 instead if all you need is the ability to dial out to or receive calls from the PSTN.
