I am wondering if it would work if I purchased my own gateway instead of using the one furnished by comcast for $11 a month. I only use the gateway for phone service since I have my own router and modem. I realize that it must be compatible with Xfinity, but is there anything else I should look for? It should be a simple call to activate the device on my existing account/Xfinity phone number, correct? Im looking at a T6862G/CT from a retailer. Please let me know if there may be any issues.
Anything on the compatible list that supports phone will work.
Look for "Voice/Telephone Enabled" in this article.
