phone system hasn"t worked properly for the last two weeks. I need a tech to come and analyze what the problem is. The rings but there's no correspondence from the other end. I can pick up voice messages.
Because this is a user to user community forum, there is no one from Comcast here that can check your service.
The suggestion is always to try first resetting the telephony modem by pressing the small indented button on the back of the telephony modem where the cables attach. If that doesn't help, then unplug the phone cord at the L1/L2 jack and plug in a known good wired telephone to give it a test. If it then works, it would be issues with your inside phone wiring, jacks, splices or equipment.
If it doesn't work connected directly to the telephony modem, then please contact Comcast support for help at 1-800-266-2278, they can do a health check on the modem and decide on what it will take to get it fixed.
I just joined Comcast Xfinity bandwagon and stuck with the same issue. Many callers are trying to reach us and get message that "This number is no longer in service". Called Comcast and they made ONE test call. It went through so they said they can not do anything more. But I am having problems all along. Many people can not reach us. Since many of you are having issues, keep posting here and someone higher up in Comcast will care to get this fixed. I had Vonage for one year and ATT for 11 years and had NO ISSUE AT ALL.
