Solved Yealink W52P + W56H cannot provision

[Glen.c]

I've got a site with a W52P which is running firmware 25.80.0.15.

The base has 4 phones hanging off it which are W56H handsets which are running firmware 61.81.0.30

The 3CX instance is sitting in the cloud (lightsail) and is it up and running.

I have an SBC which is up and installed on site and connected.

Router has no SIP ALG (i've disabled it but having it enabled doesn't help either).

I've tried a forward of 5060 udp/tcp to the SBC and without, neither make a difference.

What i've done is, go into 3CX, create the FXS/DECT yealink handset > selected the right model (W52P) and put in the MAC > Set 3CX SBC Remote > Put in the LAN IP of the SBC > selected the extensions and saved.

I've then gone into the Yealink > factory reset it > logged back in and gone to the Settings etc and put the provisioning URL in and hit save/provision.

The accounts never get populated in the yealink, they just remain blank.

Any idea what i'm doing wrong here?

Hi,

Upgrade to the 3CX firmware for the W52P available here (https://www.yealink.com/products_48.html) and retry the provisioning.

Should work.

Absolute champion. Worked like a charm.

Nice !
If the provisionning not work, try this everytime, 90% of the time is about firmware that not certified with 3CX.

Glad to hear it was sorted mooseman. Make sure you remove the forward!
