Cloud 3CX / BLF not working

[johnvam]

Hello,
I stared using 3CX installations on Google Cloud. Everything works great except BLF. I'm using mainly Yealink devices without auto provisioning. I setup the devices manually.
Is this firewall issue? On 3CX installation I change the default ports for HTTPS and SIP.
Any idea?

Yes, provision them properly.

Yes, provision them properly.

BLF works only with auto provisioning??? can't work with manual setup of the phone?

Explain more on the setup

You say you have manually setup the yealink phones, how have you provisioned them - vpn or stun.

Why have you manually configured the phones ?

I do not use the Phone Provicioning of the 3CX. I setup the devices manually and BLF is not working
I add the 3CX public IP on yealink sip server

If you manually provision then you have to manually set up BLF as per the phone manufacturers instructions...

Hi @johnvam

We recommend that you use our auto provisioning as it will take care of things for you and ensure that all the supported features will work. That's how the system was designed and that is the intended way of use.

That being said, if you auto-provision one phone then you can log on the interface and see what auto-provisioning does so you can do it manually for your other phones. I would not recommend this though, if you leave things behind then your PBX will not function as intended and you will not enjoy the benefits.

If there is no specific insurmountable reason that compels you to do things manually, then you would be better of to take advantage of auto-provisioning with our latest supported firmware.

By any chance are these EOL Yealink phones? Because they can still be made to work with auto-provisioning.
