I need some help getting this feature to work.

I just received a bunch of Yealink T-28P phones and plugged them in to the network and manually changed the VLAN to my voice VLAN. The phones now have a DHCP address and are on the same VLAN as 3CX. The server can ping the phones just fine but none of the phones are showing up automatically in 3CX. I am running SP5 and I have tried firmware 2.51.0.10(came on phone) and 2.60.0.60 (latest). I have 20 new phones connected but none are listed as NEW under the "Phones" menu in 3CX.

Any ideas on getting them to show up?
I've turned the Windows firewall off on the server.

Thanks!
 
Re: Yealink Plug and Play

Well I found the "Phone AutoDetection Update" under "Other Updates" but my issue remains.

The phone I manually configured shows up as well as my soft phone but no phone is being "Auto-Detected".

I reboot the server and the phones after the update.

Still lost...
 
Re: Yealink Plug and Play

Make sure your windows firewall is OFF on the server. Assuming that you have a managed firewall to handle your VLAN needs, make sure that you do not apply any filter at Layer 2 (or Layer 3 if that is what you have). It is surely a network issue.
 
Re: Yealink Plug and Play

The network (VLAN) should support multicast.
 
Re: Yealink Plug and Play

But many switches have the option to filter off multicast and or multicast storms. If that is enable it could prevent the function. As a matter of fact I tested that right after I replied and indeed no NEW NEW Yealink shows up

If traffic is blocked (independently of reasons) then there is no way to deliver information.
It is the rule.
 
Re: Yealink Plug and Play

After some testing I'm looking closely at the VLAN setup.
I have 3CX and the phones on VLAN 75 with no luck BUT if I leave 3CX in VLAN 75 and place a phone in VLAN 1 plugged into the same switch it works!
I use HP procurve switches.
I'll look at the multicasting option now.
 
Re: Yealink Plug and Play

Well I'm a little stumped.

I have 3cx Server configured for VLAN 75(192.168.75.150) on a HP Procure 2650 Switch (Managed) on Port 9.
I have a Yealink T28P (FW 51) connected to the switch and configured for VLAN 75 on Port 11.
The phone gets a proper vlan DHCP address and the server can ping the phone and connect to the web interface.

Multicast Filtering for VLAN 75 is off.

Here is the switch config if it helps someone figure out why the server cannot communicate with the phone for auto detection.

Thanks!

Re: Yealink Plug and Play

Can I use wireshark to view the broadcasts 3cx sends to the phones?
 
Re: Yealink Plug and Play

Yes you can, install wireshark on the server and it would help if you add a mirror port to port 11 on another port and connect a laptop with Wireshark there too. Ideally you will see multicasts on the laptop that will not reach port 9 (server).
