===== DHCP =====

  * Not all Yealink firmware supports RPS
  * RPS is supported on brand new phones
  * You can also use DHCP Option 66 to pass a provisioning URL to a Yealink phone
    * Be patient when reprovisioning as it sometimes takes a few minutes and the phone may reboot again
    * Use the same URL as with RPS
      * FreePBX Commercial EPM example URL: http://192.168.50.30:84

Yealink RPS is a free service that redirects a Yealink phone to provision itself.

The system works automatically after a vendor registers a MAC address of a new Yealink phone and assigns the proper provisioning server.

:!: Four types of URL are supported: http, https, ftp and tftp.

:!: **Not all firmwares support RPS.**  When troubleshooting, suspect this first!

===== FreePBX Commercial End Point Management =====

:!: The firmwares downloaded by the FreePBX EPM do not support RPS as of 12/13/14.

:!: You can get the phones to change VLANs with auto-provisioning setttings.

  - New phone boots (has RPS-compatible firmware)
  - Phone gets IP address from DHCP server on 'data' LAN (untagged)
  - Phone contacts RPS and gets a provisioning URL
  - Phone gets configuration from provisioning server
  - Phone downloads and upgrades its firmware from the provisioning server (if newer)
  - Phone reboots into proper VLAN with proper configuration
  - Phone gets IP address via DHCP from PBX DHCP server
  - Phone registers extension with PBX

Configuration settings needed with phones on a separate VLAN but sharing a CAT5 cabling plant (using the switches in the phones):

<file>
network.lldp.enable = 0
network.vlan.dhcp_enable = 0
network.vlan.internet_port_vid = nnn
network.vlan.internet_port_priority = 5
network.vlan.internet_port_enable = 1
</file>

:!: LLDP may confuse the phone VLAN functionality.  It did on a Zyxel GS1910-24HP switch.
