Anybody else have this problem: Starting this morning, I can onlyl talk for 5 minutes or so and the call drops, instant dial tone.
Edit: Ah, I see with a search this is a big problem with Comcast. Bummer.

First steps on troubleshooting your phone is to take a good wired phone and plug it in the L1 jack on your Comcast EMTA phone adapter, and test the line for the same trouble. Next step is to press the small recessed "reset" button on the back of the EMTA and give it 5 minutes to reboot. Test your service again.
You need to test it without any cordless phones in the loop. A cheap wired phone is available at all big box stores for $6, and is good to have for troubleshooting.
If these don't help, then you will need to contact Comcast support for help, they can look at the status and signals coming into your EMTA and determine if it is equipment, account or signal issues and they will do what is necessary to fix your issue. A tech visit might be in order to fix it.

Okay, I'll bite. So what is an EMTA and where would I find one?
I am using a wired phone on my office line, no other phones connected to that line. We have a second line, all cordless phones, happens there too.
Seems to happen at 4 1/2 minutes, very consistent.
Internet seems fine.

The EMTA is your combo cable modem and phone adapter, usually a Arris brand but could be RCA or Motorola.
Usually if your Comcast digital voice is going out, so will your Comcast internet. I would then just call it in and they will look at your equipment logs and status and they will deterimine what the next step is to do.
If could be upsteam noise issues from somewhere on the outside plant like from a neighbor sending interference up the line, this is stuff the tech can find.

Ah yes, the cable modem. I will try the reset button.
I do have a call in and a technician scheduled in a couple of days, was wanting to see if there was anything I could do here.
Internet seems to be working fine. I can call out and receive calls, they just can't last more than 5 minutes

Just check that your F connectors are snug at all points in the home including the back of the modem, wall outlets, splitters. Finger tight, but you can snug them with a 7/16 wrench, just don't over tighten them.
The tech will check your signal levels, cabling and his equipment will show if it is more serious outside plant issue, or if splitter changes are in order.
Your have no trouble with your ON Demand?
Please post back after the tech visit and share what he finds.

Well, after the reset, it looks like things may be fixed. I just did a 14 minute call to my cell, and no drops. I have an hour conference call at the top of the hour, guess that will be the final test.
Thanks for the help!
