Xfinity Voice Home Phone

Is Xfinity voice home phone encrypted? I have a VPN on my cell phone to encrypt voice calls. I just want to make sure my calls are secure. I live in an apartment and the telecom closet is always being accessed which holds everyone’s connections.

Hello @user_054362 We appreciate you taking the time to reach out to us today. I know how important it is to ensure any communication lines are secure.

Here is a breakdown of our Voice services.

Comcast can take advantage of a feature called Quality of Service because the public Internet is not involved in the transmission of the customer’s calls.

Quality of Service means that Xfinity Voice data receives priority over all other types of data on the Comcast network, eliminating problems with latency and IP packet loss that can affect call quality.

Although many Internet VoIP providers do take steps to secure their customers’ calls, those calls are transmitted over the public Internet, which means that there is a possibility of those calls being intercepted by a third party. By contrast, Comcast does not use the public Internet at all to connect customers’ calls, which means that they are as secure as using a traditional land-line telephone.

Please let us know if you need help with anything else. We are always here for you.

@XfinityJessicaA but do you offer TLS and SRTP call encryption? Call interception is common. Where I live the data closet with all residents cable and phone is left unlocked at times.

To help ensure secure encryption methods and safeguard your data, we’re discontinuing the use of older versions of Transport Layer Security (TLS) that have been deemed less safe.
TLS encrypts or conceals communication between two parties. TLS uses certificates to authenticate the identity of the parties.
Comcast’s email system will support version 1.2. Comcast will discontinue the ability to connect through TLS 1.1 and lower. This means older and most likely end-of-life applications/devices will no longer be able to connect to Comcast’s email system.
If you have an out-of-date application or system, we recommend:
Updating your device or the software you use to access your https://comca.st/3Rz7adb email or
Speaking with a trusted resource about updating your device or the software you use to access your https://comca.st/3Rz7adb email.
Older versions of TLS are known to be insecure. Comcast relies on TLS to encrypt and protect your data in transit, including any data you send using your https://comca.st/3Rz7adb email address.
If your device or email application isn't updated before we discontinue older versions of TLS, you’ll need to use Xfinity Email in your internet browser to access your email.

I no longer work for Comcast.

Um ok, this is my problem with Xfinity customer service. You told me all about the technology but will not answer the question. I got it, your phone it’s not encrypted. If your internet line is compromised the voice calls along with the cable tv activity is compromised correct? Just yes or no.
