Solved Fanvil x4u-v2 router phone not connecting on SMB

[Terri Griffiths]

Hi All,

Brand new phone - x4u-v2 bought to be a router phone -

• Latest version firmware - details displayed on Fanvil phone portal X4u-V2 - V2.0 - 2.12.16.17
• Shows my name & extn details on display that is on the 3CX SMB Admin portal.
• Shows in the Voice & Chat area as 3CX SBC Router phone - but has a red square next to it.
• But won't call internally to another user, nor is it displaying changes made to my extension like a BLF amendment.
• Fanvil portal doesn't look like it's updating with changes.
• Still waiting on my SIP trunk that has been on order for a week, but I understand from Nick the fab 3CX trainer, that is should still work internally.

Can someone let me know if on SMB I must have SIP trunks to even dial internally? So I'm not chasing my tail here?

Many thanks in advance...

Terri

That was how I did the factory reset on the x5u. Which took it back to v1, and then wouldn't let me upgrade to V2...

Don't worry about it, just factory reset one more time with the OK button and let us know if the phone provisions after 2 mins of coming back online.

Excellent news! Just a couple of clarifications here:

X5U (not router capable) and X5U-V2 (is router capable) are two entirely different models (different hardware inside).
The V2 is a hardware version, firmware will not change that fact. It will also appear in the web UI of the phone.
Here is what you would see on a V2 to tell them apart: Revision B



And the second part, the reason this happened was because the phone had the wrong firmware the first time it connected to 3CX. The router function was not activated and the phone tried to connect to 3CX insecurely and got blacklisted.

Our handy guide has the instructions in the right order: https://www.3cx.com/sip-phones/fanvil-x3-x5/

As a bonus, you can now also use your V1 Fanvil X5U device on a second user so it won't go to waste.

Just add it as a "Normal phone" and make sure to select your X5U-V2 to act as its router.
They both need to be on the same LAN of course so they can reach each other.

Firmware can be found here: https://www.3cx.com/docs/phone-firmwares/




PS: If you are away from your phones (or the power/internet is down) we also have apps for iOS, Android, Desktop, and a Webclient to allow you to have access to your extension pretty much anywhere in the world.
