VOIP, Sipura Phone Adapters, etc.
I bought a Sipura SPA 3000 phone adapter a few months ago so that I could set up a home phone system using Asterisk combining VOIP and my land line. My goals were to:
- automatically route long distance calls using an internet VOIP carrier
- route local calls using my existing land-line
- enable me to use a soft-phone (and headset attached to my computer) to make and receive calls
- have asterisk serve as an answering machine (and email me my voicemail as audio attachments)
- existing phones should function normally (i.e. the user shouldn't need to know anything about the system)
I've been able to achieve all this and more, and have been amazed by how well it all functions. Of course, it did require me to read much of the Sipura user manual as well as the Asterisk/VOIP wiki for documentation and clues.
In setting this up I found it useful to be able to back up the configuration of my Sipura and compare it to previous versions, so I wrote a small utility in Python called spaconf for this purpose. Maybe someone else will find this useful as well.
So far I have used both Gafachi and Voxee as carriers. Voxee is cheaper, but I think I experienced fewer glitches with Gafachi. There are many carriers to choose from.
If there is interest, I can include more specific details about my configuration in a future post.
