Hi team,

Ever since I've upgraded the firmware for the ER707 from 1.2.0 to 1.2.1, I noticed that a few things has stopped working normally.

1. All IP Phones in my office can no longer connect, it says No Service, but the LAN ports connected to them is working just fine. Have not whitelist any ports specifically for SIP, since last time, it wasn't required, and the IP Phones worked just fine.

2. MQTT Explorer can no longer connect the our Node Red server, even with port forwarding the specific ports required for it. Previously, it was working fine.

Please help.
