Auto Provision "On the Same Network"

[kylejwx93]

Hi all,

I'm looking at the instructions for PnP provisioning and this page says "phone must be on the same network as the PBX." I'm not a networking expert. What does this mean? They need to be on the same subnet or VLAN? Can they be on two different VLANs, but have some fancy routing that allows communication across VLANS?

I'm using Yealink phones if it matters. 3CX is virtualized on VMware.

Hi Kyle,

Ultimately, the PBX and phones side need to be

a) able to communicate (traffic should freely pass between the two networks)

b) and especially you need to allow SIP multicast on your network https://www.3cx.com/docs/plug-and-play-ip-phone/

This generally means a single subnet where the PBX and phones are on the same IP range and can reach each other unimpeded. If you have something else in mind, you will have to do some testing of your own and possibly adjust your network elements accordingly.
