Vonage business call issues with cga4131com
We have been using Vonage Business for years, and about 2 months ago changed router to a comcast cga4131com. Been working fine until a couple of days ago where could not transfer calls between numbers. Vonage says there are "Bumps in latency" and the "Voice over IP is not a good signal" and to check with ISP.
They provided me with their list of supported devices (https://businesssupport.vonage.com/articles/answer/Settings-for-ISP-Modem-Router-Gateways) and this device is not on it, but it has been working fine until a couple of days ago.
Wondering if anybody else saw something like this.
