configuration from the 3CX Phone system HTTP server and automatically configure
itself. For more information how this works, see
http://www.3cx.com/support/provisioning.html. You can find configuration guides for
provisioning popular IP phones at http://www.3cx.com/sip-phones/index.html. For
larger networks it is recommended that you provision the provisioning URL to the
phones via DHCP option 66. See this configuration guide for more
To provision a phone, simply enter the MAC address of the phone (which can be found at
the bottom of the phone), in the MAC address field. Then select the appropriate phone
model and the Network interface (in case your phone system has multiple network
interfaces)
Optionally specify any BLF fields that must be automatically provisioned too. Match a BLF
button with an extension, so that this button will show the status of that extension. The
number of available BLF buttons varies per phone. 
Testing your setup
As soon as you have created at least 2 extensions, and configured SIP software and/or
hardware phones to work with those extensions, you can test whether your setup is
working correctly. To do this:
1. Check Phone System status with the status monitor
Screenshot 5 - The Status monitor
Load up the 3CX Phone System Management console, and click on the ‘Extension
Status’ node. Check that all extensions are listed and are ‘Registered’.
