Problems with FXO/FXS

I have had some issues with setting up Asterisk to work properly with a home phone. I have installed Asterisk using Elastix.

The first problem that I am having is the phone will ring 2 times every 15 minutes. The call seems to be originating from Asterisk. This has happened previously when I installed using Trixbox. I have yet to find a reason for the phantom calls.

The second problem is with the caller ID. It will not display any caller ID information for the incoming calls. I have checked and double checked all of my settings.

Any help is greatly appreciated. Thanks.

We would need a bit more information to help diagnose your problems. What are you using for your FXO/FXS device? Is it a digium card in the computer? Someone else’s card? An external ATA plugged into the network?

If you had the same problem on a previous install of a different distribution, perhaps you need to look at a hardware issue. See the first question.

I believe it’s a China Roby x400P with 1 FXO and 1 FXS module. It is very odd though because when I first set it up everything seemed to work fine, but after about a week it started this issue. It didn’t seem like it would be a hardware issue. Thanks.
