Here's my issue:
My system keeps saying there is a voicemail on the Comcast system but there is not. I tried refreshing the indicator though XFINITY connect but it refuses to refresh it. If someone from Comcast could forcibly refresh the new message indicator and remove some corruption on the system for voicemail that would be great. Even the dial tone indicates there is a voicemail but as I said there is not.
Try this: Call your home phone from a different phone and leave yourself a VM. From your home phone, retrieve the VM and delete it. Does the MWI and stutter tone then go off after doing this?
So, a week or so ago I got a letter from Xfinity saying that they wanted to send me updated equipment. I went online and ordered up the new equipment; it arrived and I started reading the literature prior to installing. Lo and behold, I discovered that my new Xfinity Technicolor DPC3941T gateway device did not have a battery backup like my current Arris device has. If I was using the device for normal internet and voice operation this wouldn't be a big deal. However, my home security system is connected thru this device and if there is a power outage my security system needs to be able to dial out since it has its own battery backup.
So, do I send this new device back since it is less capable than the current device? Or do I have to go out and find a backup battery on my own nickel to fill the empty slot in the new device?
Thanks in advance.
Comcast stopped sending batteries for devices on Feb 26, 2013. For anyone requiring security from power outages, I always recommend a UPS system and NOT a battery in a device as I prefer to keep the power managed on many of my devices ( TVs, Cable Boxes, Gateways/Modems, Routers, Monitors, CCTV systems, Weather systems, Alarm systems, etc ).
If you want the device battery, The Cisco battery part number is 4033435. Specifications are 10.8V 2600 mAh. You can find it at many online retailers ( I prefer Amazon myself. )
This is some type of Porting issue somewhere
Whether it is the fault of Apple, AT&T, Comcast, or some combination thereof, if its a major issue, the FCC regulates the number portability process. What Device dials a PSTN Connected Number should have no bearing on whether a call completes (That whole Common Carrier, thing...)
If numbers are not porting properly, attempt resolution with your provider, in this case Comcast, and if not satisfactory, that is why the FCC has a Complaint Process
So in theory, is this related to VoLTE and routing between AT&T and Comcast? One way for end users to check: Disable LTE Voice (ie Setting -> Cellular -> Enable LTE -> Data Only instead of Voice & Data) on the iPhones that aren't routing the calls, and see if that corrects the issue
Would make sense why a newer iPhone would have problem, and if AT&T disables LTE Voice access for that device from their side, it would complete the calls, too...
I don't know if that is whats going on, but its a theory that fits the given facts
can a dual band802.11 modem router be bought from comcast
Comcast does not sell devices for retail purchase, but you can get these online through many other outlets ( Amazon, BestBuy, etc )
I have 2 phones. One is wall mounted and one is an extension in the bedroom. What do I need to do to connect and have it activated? I recently "bundled" and have connected the TV and computer OK.
Providing that you internal phone wiring is okay, you can attempt to connect a phone line from TEL1 of the modem/gateway device to an unused phone jack in the residence. This will "backfeed" the other phone jacks and provide signal for the phone sets to work. Also ensure that your previous phone provider's line has been removed from the outside DMARC box as this can cause issues with the CDV phone service,
Comcast gives no info as to how to use the phone backup battery. It does not work automatically. You have to plug in your landline phone somewhere on the modem, but where???
You're asking 2 things.... battery and where to plug phone in.....
Battery is installed in the battery compartment and Comcast is no longer supplying those so User's wishing to use the device's battery must procure one from a retail vendor.
Phone Line is usually connected to TEL1 of the device. If TEL1 doesn't work, try TEL2.
I've read online that routers (mine is aDCP3941T) and cordless phone can have a negative effect on each other. It have episodes where the party calling me or the party I call cannot hear me. A router reset always fixes the problem. Anyone know if there can be a conflict here with wi-fi and my cordell phone and is there a solution?
Yes. Ensure that your cordless phone is not near the DPC. Another thing to consider is the channel that the cordless phone is on ( base set ) and the channel the DPC is using for 2.4Ghz. Change the phone to the opposite side of the range the DOPC is on.

I was Xfininty customer in California in 2014-15, then i moved to PA over there also i was xfinity customer and was using Modem ARRIS WBM 760A until end of 2016. I moved to Washington recently and when i called xfinity to start new connection at my apartment, they say Modem ARRIS WBM 760A is not supported.
Can anybody tell me what happened in 1-2 months that they removed this ?
Also if anybody currently still using this modem ?
That model is no longer supported on the Comcast network. You can review the approved devices using this link: https://mydeviceinfo.xfinity.com/customerinfo
