[gregory.b]

Hello I have an issue at a client.

I want to add a phone as a Router Phone on his 3CX but it seems that it no longer give me the Choice between Router Phone or Normal mode when i click on Add Phone when am connected on the User Extension in Add IP Phone.

Can you tell me why ? and How i ca add the Phone its quiet urgent



It give me this menu

When i put the model and MAC address

I can choose other SBC phone but can't create a new

Is there a Limitation.

Note that there are already 2 T57W set as Router Phone.

No limitations, go right ahead to the next page and select connect directly.


But make 100% sure you have our firmware installed before you go ahead

Thank youuuuu now i see where it went
I thought the Connect directly was for Stun etc

The phone was set as router phone but didn't appeared connected
I asked the client to unplug then replug the phone to see.

STUN is no longer supported in V20, but luckily this model is a router phone.

1. Make 100% sure that the phone has this specific firmware from here otherwise it will not be able to become a router phone: https://www.3cx.com/docs/phone-firmwares/

2. After the firmware is installed, you must factory reset the phone (very important)

After this, the phone will download the router config, enable the built-in SBC and finally it should become registered.

If that didn't work, make sure you delete the phone and add it again the same way, and factory reset again. It has to be done in this specific order: First firmware, then add in 3CX, then factory reset
