3CX SBC with Multiple VLAN Support

[Nicarlo]

Hello,

I'm currently running an enterprise version of 3CX v15.5 w/ latest service pack.

This instance is hosted in a remote location (datacenter).

I have 4 remote offices connecting to this hosted 3CX, all 4 of these offices have their own on-site SBC configured.

I'm currently working on a new site that will have a separate VLAN for the phones.

VLAN 1 - Regular network

VLAN 10 - IP Phone network

In the 3CX management interface, under the extension -> Phone Provisioning, I included the following VLAN configuration.


Now for my questions.

Given the SBC is on the VLAN 10 network there is no way for it to see the phones until they are provisioned and the phones cannot get provisioned via the SBC until they are set to VLAN 10.

Is my only option to manually set every phone to VLAN 10, then provision it via the SBC?

If I were to add a second NIC to the SBC instance would i also be able to monitor a second network in parallel?

I'm interested in seeing if anyone else have come across the same situation and how they dealt with it.

Thanks!

Don't put VLAN settings into your provisioning files, let the voice VLAN function on your switches handle it.

If you don't have switches that can provide the LLDP-MED messages then look at how your chosen handsets can pick up their VLANs via DHCP, and add this option to the DHCP scope on your default VLAN.

Agree with above,

Set the vlan via your switch using the voice vlan settings

or

Set the vlan via dhcp -

Also agree with JonnyM. Just because 3CX has that option doesn't mean it's the best way to do things.
