VoIP with House Internal Wiring
I recently converted my phone service from AT&T landline to Xfinity VoIP, using the latest Xfinity modem/gateway. I have my telephone line connected to my modem through my house internal wiring. This works fine EXCEPT that when I receive an incoming call, the external phone rings are "clipped", that is, the first ring is normal, then subsequent rings are cutoff after a short chirp. All other aspects of the phone call are normal, including the ring sound heard by the caller.
If I connect my phones directly to the modem (not thru the house wiring) everything works fine. Therefore, technically this is not a Xfinity/Comcast problem, but something to do with my house wiring. But I am hoping to get some ideas from the community on what may be the problem? Thanks.
