I work from home and have an avaya IP phone from my company. This phone works by internet, not the phone line. We have updated to the higher speeds and needed the highest speed compatible router. We’ve had this before and it keeps disconnecting from the work phone. It’s a little hard to explain, but anyone who has a similar situation hopefully will know what I mean. I log into the phone with an extension via a VPN with my work extension. Again this uses WiFi, not phone service. Any ideas why the faster router is disconnecting my work phone but the older “slower” model does not? TIA!
