I have been using VOIP (not RC) for quite a few years. I still use voip.ms for my home phone and now RC for my business phone. Sometime last year Comcast told us to replace our modem with a new one as the old one was "not supported" Right after the modem was replaced I am pretty sure was the start of my VOIP problems. When the uplink channel is busy VOIP gets messed up and outgoing voice chops, breaks up and is of lower quality. Calm the uplink and all is ?OK? most of the time.
So here I go getting signed up to be a RC partner and I install my system and of course it works better than voip.ms but it is still effected.
Further training and research into routers and we decide that I should get a router with QOS. Well RC has this nice list of either VERY EXPENSIVE or OLD routers. (hey 802.11AC is here folks N is dead). Anyway I get a Netgear R7000 because it appears to be close to what I need and has QOS. RC has not updated their FAQ for newer router so I play and I have QOS turned on and it "may be better".
I cannot sell this to my customers. I cannot make it work for me. Does Comcast Win? Do I just chuck it in and go cellular?
We will start another thread about routing issues......
PS Comcast 30mb x 5 mb low jitter VOIP testing says it will take 57 lines.
PPS with VOIP.MS and a OBHAI 202 router between the network and the cable modem I still get bad data.
