Yealink phones, no service

[Jason Aday]

Hello,
I have a new 3CX install on Linux, v16 update 2, imported extensions from CSV, went to provision a couple phones to test with the client, two T58V's and one T42s, the first T58V I setup provisioned correctly, the other two provisioned, but show no service on the display and register failed when looking at the phone web gui.

I disconnected the T58V that was working and rebooted the other T58V that wasn't working and it came up. I plugged in the original working T58V and it shows no service now. Sounds like a port problem, but this is all local lan. The activity log doesn't show anything on that extension trying to register.

Anyone have a thought on what to check?

As you have imported the phones config via csv the phones do not have the provisioning url, you need to use dhcp option 66 , using http option

Reboot the phones, and if the phone setup in 3cx is correct the phones will provision

Instead of adding the phones by csv you could use plug and play (PnP provisioning), as the phones are local to 3cx (same network range)

I'm not understanding, I didn't add phones via CSV, just the extensions, I went in added the phones mac address and provisioned with autoprovision using the URL. I was going to setup DHCP option 66 next week to see if that helped. It's working, just only one phone at a time.

What is the IP address range ?

Any vlans involved ?

If you connect a pc on the same network, can it ping the 3cx server

On the lan settings, for the phone are you using IP address or fqdn ?
