Comcast Telephone Service issue
 

I have been experiencing an intermittent problem from all three of my phones. Occasionally the person on the other end of the conversation cannot hear me. Anyone else experiencing the same issue with Comcast telephone service?

Could be a number of things. You are going to need a computer guy (not a Comcast guy)....I presume you have phones (RJ11) plugged into the back of yoru Comcast cable modem...??

Try resetting your cable modem that sometimes helps.

While correct, we come in to asking "why". The dial tone, television, DVR and potentially security systems all run on the same bandwidth. So, if you are watching your DVR or OnDemand, and someone is online (as any computer that is turned on is for the most part) and you have other things - then you will see latency on the dial tone. You dont notice it on data - but on dial tone it is quite clear that there is an issue.

I have a complaint with crimes against seniors about this issue with Comcast. Comcast has been to my house 3 times and the VP of Comcast is involved. They have a issue with a peace of equipment in one of their offices which they don't want to change do to the cost. Call C.A.S and let them file a complaint for you. It is the only way we are going to resolve this issue.

That is not exactly correct. Comcast is having issues with QoS on and IP Priority. The fact is, ALL local to our area Comcast calls are routed (via IP) out of Colorado. Simplest solution for end users is to get their own Cable modem and their own (voice) service. Then with the right devices you can give 802.x priority to voice traffic.

This is EVEN MORE IMPORTANT for people with "POTS" (Plain Old Telephone System) lines for their CPAP, Pacemakers, LifeAlert and any other system that requires dial tone.

If your life depends on your dial tone - DO NOT use Comcast.

NO, the best solution would be that Comcast fixes the problem and the customers get what they are paying for. So let Comcast know your displeasure.

Google "Honest Cable Company". I have worked with Comcast on the IT side for internet and telephony for thousands of handsets and up to 10GB fiber connections for going on 20 years....trust me - they dont care.

Like I said, the SIMPLEST solution is to get your OWN cable modem ($80 +/-). Not get aggravated, not flare up your blood pressure and not pay them monthly for their device.

Yep. Don't over-complicate.

If you want to try other systems, that's cool. But the SIMPLEST solution to the problem described by the OP is exactly what birdawg says.

And keep Comcast on speed dial. Oddly, they farm out all of their local work to a company called RWL Communications who has an office in Leesburg (their trucks say Comcast on the door). You can call them over and over and over...or, save money and simply get your own device (and oddly it also works reliably).

Too bad Comcast is not regulated by the FCC like the common carriers are (ATT, CenturyLink and other CLEC's). THEN and only then would the OP have ground to stand on, but right in the contract with Comcast there simply is no SLA, no promises and simply - they dont care because they dont have to.

I have had the same exact issues off and on for the past month as well - past week seems OK again. About two years ago had the same issues and Comcast told us everything on our end, from what they could see was fine, very frustrating to say the least. Hence, the issue stopped and as mentioned it did start up again. I am really glad you posted this because I thought it was our telephone as they had told us the first go 'round.

Boy , do I feel lucky. 3+ years of Comcast internet/phone service without a hitch.

OP...I know Comcast is far from perfect. But don't let some posters convince you that it's impossible to get good service from them. That's simply not the case.

Another fun fact about Comcast. If you have their device (first off, it is NOT a firewall). But, their device with their WiFi they are also broadcasting an SSID called "xfinitywifi". This is an available connection for anyone with a Comcast username/password to connect to YOUR bandwidth. So, if you connect to "xfinitywifi" - you may be connected to your house, your neighbors and they may be connected to you - and the fun part. You dont know it!:22yikes:

You can log into the cable modem and disable the xfinitywifi SSID, but - sort of an advanced user thing to do.

The resetting of the cable modem is resolving the issue because it is resetting potentially latent connections from devices that are online. So, bandwidth is freed up and away you go.

I worked for Verizon for 35 years in the special services department. I worked for 4 US Presidents during my time with them. When we had a problem with our service we made sure the problem was fixed.

I agree with you 100% - but Comcast does not have the same Federal Regulations and quality of service as the TelCo's...to this day you can get 5 - 9's from a CLEC, but no SLA from Comcast. :beer3:

I have my own secure network through my own router. All I care about with Comcast is a stable connection and that's what they've given me.

Me as well. I dont have (or need dial tone). But, as I said earlier - I would never trust medical equipment to ride on their dial tone.

I have a sorta high end edge device and can see so much trash on the network it is not even funny.
