I use the NoMoRoBo service that works great with Comcast except for the annoying first ring. I purchased a ring suppressor called a FRS22100 First Ring Suppressor Silencer for Robocall blocking services off of Amazon. It suppresses the first ring correctly but fails to pass the caller id and only says incoming call. I have verified that the device should pass the caller id and for many it does. According the the manufacturer, there are some VOIP that do not work and evidently the xfinity ARRIS GROUP, INC. TG3482G is one of those. Has anyone used this device with the xfinity modem and had it work to pass the caller id?
