If you are leaving Verizon Onetalk and want to reuse your rebranded Yealink T46G, Verizon doesn’t make it easy. If you try to web in to the phone, you’ll find that the web interface is disabled. Here’s the process summary:
- Disconnect the phone from the network and power it on.
- Do a factory reset (don’t connect it yet)
- Enable the web interface and reboot it (don’t connect it yet)
- After the phone has completely booted, plug in the network cable
- Web in to the phone
- Upload the current firmware from yealink
I found the steps above on reddit. https://www.reddit.com/r/VOIP/comments/6nk7qx/flashing_verizon_t46g/
The process is easier if you have a Yealink power adapter.
Unplug the data cable and restart the phone.
If your phone is running the Verizon firmware, the menu will be all red icons like this:
When you try to open the advanced menu, the admin password is admin, but you have to put in the password like an old school cell phone 2-3-4-666-44 so that it reads admin. Go under the advanced menu and select Reset & Reboot. Then select Reset to factory settings.
Say OK to the warning.
The phone will boot and look the same. Go under the advanced menu (you have to put in the password like an old school cell phone 2-3-4-666-44 so that it reads admin) and this time go under networking. You will now have a new entry under # 3. Select Webserver type and enable port 80.
Let the phone reboot and connect it to the network after it has fully booted. Press the OK button twice to see the IP address. Open up a web browser and log in. By default the username is admin and the password is 2-3-4-666-44 (it’s like spelling out admin on the dial pad) (If that doesn’t work, I’ve heard reports that “admin” will work.)
Once logged in, click the settings tab and then upgrade. Go to http://support.yealink.com/documentFront/forwardToDocumentDetailPage?documentId=10 To get the latest Yealink firmware. Click upgrade and let the phone reboot.
As it reboots you’ll notice it reboots with a different screen than the Verizon one.
When it finishes the firmware update, it will be running the typical Yealink setup and you can program it for your PBX.
I have tested this process on the T46 models and the T54 models and this process works on both.
