2/28/2019 How to Auto Provision a snom PA1 for 3CX version 15

There are several methods to provision a phone:

● Plug & Play - For phones on the local LAN or behind the 3CX SBC.

● Manual Provisioning - For phones on remote networks that will connect directly to 3CX and use STUN.

For more information, see “When can I use which provisioning method?”

Local LAN or SBC: Provision via Plug’n’Play

1. Connect the phone to the network. A PnP request will be sent automatically to 3CX.

2. Go to the 3CX Management Console ⇒ “Phones” page. The new phone will be marked in Bold.

3. Click on the BOLD entry and choose between “Assign Ext” or “Add Ext”, depending on whether

you want to assign the phone to an existing extension or create a new one.

4. All major provisioning settings are pre-populated. If your PBX has multiple network cards, select to

which network this IP phone is connected.
