Sangoma P330: wrong VLAN membership with LLDP

I have few Sangoma P phones (P310, P330, P370).

P310 are on a dedicated ethernet connection, but on P330 and P370 i use the PC ethernet port to connect a pc.

Uplink switch is a Ubiquiti UniFi USW-PRO-48-POE, the ports are configured with the Voice VLAN and LLDP-MED features.

So the phone should go in a VLAN while the attached PC should go in another VLAN.

First of all I noticed that on a factory default phone, the LLDP is not enabled, so at first boot the phone end up in a wrong VLAN. This is very annoying because I have to allow traffic to the PBX and to Sangoma redirection servers from the wrong PC VLAN for initial provisionging. By comparison all others, even cheap, voip phones we use(d) have LLDP-MED enabled at the factory as it should be.

By the way, templates of the phones, are setup with LLDP VLAN Discovery Mode, voice and pc vlan left empty because voice vlan should be provided by LLDP-MED and pc vlan should be the untagged vlan.

This works as expected at least for P370: phone goes in voice vlan and pc stays in native/untagged vlan wich is the pc clients vlan.

On P330, on the other hand, phone also stays in the native/untagged vlan and ends up in pc clients vlan.

I suspect this could be related to this other issue I’m experiencing with P330: Sangoma Phone P330 Backgound

Hi @unlikely

Regarding your background issue, does it looks same as [bug]: Endpoint Manager Transparent Backgrounds Not Working · Issue #634 · FreePBX/issue-tracker · GitHub ?

Regarding VLAN issue, we will try to reproduce locally.

The backgroud issue is quite strange.

One first P330 is in the same site of FreePBX: is the one that doesn’t go in the voice VLAN supplied by LLDP and that doesn’t get any background image at all.

Another P330 is in another site, so again not in the same VLAN of the pbx: this one get the background image but the image transparency is not honored, bad effect on the screen.

I don’t want to say too loud, but it seems that the latest firmware 4_25, that I was finally able to auto install via EPM, solve the VLAN-LLDP issue (but it would still be nice to have LLDP enabled from factory).

And also the issue of the background (but transparency still not applied on P310/P325).
