Instructions on setting up compatible Polycom IP Phones
====== Polycom VVX 450 ======

The VVX 450 is one of the current offerings from Polycom, featuring a colour screen, 12 line keys and support for low bandwidth and high quality codecs such as G722 and Opus. They can be purchased as cheaply as £30 on EBay if you get lucky at auction time.

I found a couple of limitations which mean I can't recommend this phone for a multi-server setup:
  * **BLFs** - The Polycom incorrectly forwards them to the SIP server on Line 1. If you only intend to use one SIP server that's fine, but it's a bit of an issue if you have registrations to multiple servers and want BLF active on several.
  * **SRTP** - SRTP (Encrypted Audio) is a //global// setting, so it's all or nothing.
  * **LDAP Directory** - The LDAP directory has to be setup via the config file rather than the web interface, which sucks.

These settings may well apply to other Polycom devices.


====== Access the Web Interface ======

To find the IP address of your phone navigate to the following menu using the buttons on the phone:

''Home Button > Settings > Status > Network > TCP/IP Parameters''

Type the IP into your browser and you should be presented with the configuration web interface. If it doesn't load, try using https instead. The default password is 456.  

====== Set a password ======

Navigate to ''Settings > Change Password'' in the web interface and follow the instructions to enter your old and new passwords.

====== Configure your "Line" ======

Navigate to ''Settings > Lines'' in the web interface and select a line that's not in use. Use the following screenshots as a guide to configuring the line, using your assigned Extension Number and Password:

===== With Encryption =====

====== Configure the LDAP directory ======

**This will delete your line passwords and potentially other config data**

Navigate to ''Utilities > Phone Backup & Restore'' in the web interface:

{{:polycom-vvx-450-backup-restore.png?direct&800|}}

Press ''Phone Backup'' to download your phones configuration in .pbu format. Open it in a text editor and add the following in the <WEB> section:

  dir.corp.scope="sub"

The press ''Restore Backup'' and upload the file you just edited. The phone will then reboot, and you will have to re-enter your line passwords.

The directory can be accessed by pressing ''Home > Directories > Corporate Directory'' on the phone keypad and entering the name you wish to search for, then pressing submit.
