Re: Using VOIP to extend PSTN service over Ethernet.
I am considering a solution with Aterix or Trixbox at some point in the future when I get more lines and learn more about this stuff.
My line is working fine the way hwittenb suggested. I have some small issue that I can tolerate: My caller id information isn't forwarding from the PSTN to the extension, which I'm sure it's something that can be set up. I'm also getting echo of my own voice and a strong fade on the other party when both are talking. |

Maybe the PSTN Answer Delay setting is not long enough to let the SPA decode the incoming caller id. Try increasing the delay a second at a time until you decide that isn't the problem. I'm away from home, but I believe there is also setting to use the incoming PSTN caller id on the voip call.

Probably something to do with the gain settings on the SPA. |

| I caught another minor problem. If I end the call before the other party does (like leaving a voice message and hanging up when you're done talking) the call doesn't disconnect. After leaving a message, the phone stays off the hook and never hangs up properly. |

After leaving a message, the phone stays off the hook and never hangs up properly. Usually the problem is detecting that the pstn line has disconnected. The 3102 has a lot of options for that. Disconnection by the remote SPA is done by a SIP "Bye" signal and the 3102 will acknowledge the BYE and release the call on the PSTN line. I just looked at a trace on my equipment and that is how it works. I'm not sure what would be happening on your setup. You would have to run a trace on the 3102 to figure it out.
It is possible to setup the 3102 so that it will disconnect the call after any "long silence" period that you specify. This might be something to try if you don't mind getting calls arbitrarily disconnected when there is silence for a long period.
You can read about these subjects in the SPA3000 ATA User's Guide that you can download from www.sipura.com/support
I see you use WildBlue for your internet service. Have you found it possible to use voip at all over that type of service? The propagation delays are quite long for voip and the general answer is "no you can't use it" but I'm curious as to whether you have tried it. |

| I have tried voip in a limited fashion and so far it didn't work. It would connect and immediately drop, or there would be too much jitter to understand anything. I mean to try it more in the future and I am also planing to add second sat line in a few months (starband or unasat) and I will report on how it works. My PSTN line is my last wire to the world I would love to cut it if possible. |

| If there's an entry in your Regional tab for "CPC duration" make sure it's set to 0.75 - 1.0 (unit is seconds). I doubt this is the source of your problem for the cases where you place the call, hang up, and the call is not properly handled, but it would help for incoming calls. |

I do not understand, I had starband (100 up/500 down) and it worked very well pC to Pc .not comfortable but acceptable PC to landline.
Now I have the new plan (250 up/1000 down)it works fine both and much better with pc to landline.
Sure it is not first digital quality but very acceptable.
Why people have problem : a non accurate dish alignment?
