Important Notes

  • For security purposes, do not put phones on public static IP addresses. If there is no other option, you must at least disable the web portal on any phone device. If this precaution is not taken, OnSIP is not liable for any charges you may incur due to access to the phones.
  • All Polycom phones that reboot on our boot server are given a new web admin password. To view the password for a phone, log in to as Admin and go to the Administrators tab, select Phones and under Phone Info the phone password will be listed. 

Step 1: Locate the MAC address of your Polycom phone

The "S/N:" field is your MAC address. It should start with "0004f2" or "641xxxxx" and be a total of 12 digits. On the same screen, please note your Model as well. In many cases, this information can also be found on the bottom of the phone albeit printed very small.

On Soundpoint IP and SoundStation model press:  Menu ->Status ->Platform ->Phone 

Phone information

On a VVX-model the options are: House icon ->Settings ->Status ->Platform ->Phone


Step 2: Add the MAC Address of your phone in the OnSIP Admin Portal

Depending on the type of phone you have, you will need to follow slightly different procedures for each type: New, Used or existing.

Brand new phone

  1. Add MAC address of phone to OnSIP Admin Portal under "Phones" and assign a user
  2. Add boot server info to phone (see below)
  3. Reboot phone

Existing OnSIP Phone - New user

  1. Reassign Phone to new user from dropdown. 
  2. Reset key in the Factory Reset box
  3. Reboot phone to pick up changes

Used Phone (from another provider)

  1. Reset Device Config (See here.)
  2. Reboot phone
  3. Reset Local Config (See here.)
  4. Reboot phone
  5. Reset Web Configuration (See here.)
  6. Reboot phone (The phone is now in the same state as a Brand New Phone.)
  7. Add MAC address of the phone to OnSIP Admin Portal under Resources (see here.)
  8. Add boot server info to phone (see below)
  9. Reboot phone

Expansion Module - EM50

  1. Can only be used with the Polycom VVX450
  2. The hard limit imposed by Polycom of 50 BLF lines = Line 1 is User, next 49 can be configured as BLF
  3. LINES will be listed first then BLF
  4. Polycom imposed an inability to skip lines.  Physically possible to configure in Resources, but Polycom adjusts and moves all skipped places up on phone screen

Step 3: Add to the Polycom phone

For Polycom 5xx, 6xx and VVX

Press the menu button or House Icon on your Polycom phone. Then choose "Settings" (3), and "Advanced" (2). Enter your password; the default password is '456'. Hit the "Enter" soft key when done.

Next, select "Admin Settings" (1), followed by "Network Configuration" (1).

Select Provisioning Server.  Change "Server Type" to "HTTP", and the "Server Address" to, using the * key for the periods.


Select "Back"/"Exit" (or use the Left directional key) and the "Save Config" option. The reboot process may take up to 45+ minutes on older phones if a firmware upgrade is required.

The current version of the software for most SoundPoint IP phones on the boot server is 4.0.12. For VVX phones, it is 5.8.0 

For Polycom Soundpoint IP 3xx

Press "Menu" on your Polycom phone. Then choose "Settings", and "Advanced". Enter your password; the default password is '456'. Hit the "Enter" soft key when done.

Next, select "Admin Settings", followed by "Network Configuration".

Scroll down using the arrow hard keys until you see "Server Menu". Select it using the checkmark hard key on your phone.

Server menu

In the "Server Menu", change "Server Type" to HTTP by using the arrow hard keys and Server Address to (Hit the number 2 twice for the letter "b", for example, and the * key for periods. If you see "22" instead of "b" you are in Number mode and must press the "#" key to change to URL mode.) When done, hit the checkmark hard key to save.

Finally, press the left arrow twice until you see "Save Configuration and Reboot". The reboot process may take upwards of 30-minutes on older phones if a firmware upgrade is required.

Step 4: Reset Key

Did the phone reboot, but still doesn't work?  If so, log into the OnSIP Admin portal and choose "Resources".  Find your phone and choose "Reset Key" and then reboot the phone (Do not factory default the phone).

If there are warning on the phone, to clear the warning on the phone, choose the "Home" button and then "Settings", "Status", "Diagnostics" and then "Warnings".  Clear the warnings.


As of July of 2015, the new VVX boot ROM 5.4.0/5.5.0/5.5.1 requires https:// to access the web interface of the phone when the interface is enabled. We strongly recommend keeping the web interface disabled to prevent security issues as described above.

Please note that if you're running a firmware version prior to 3.0 or a BootROM version prior to 4.1.3, your phone will be formatted during the upgrade and you will have to reconfigure your user settings, including the line configuration unless you have entered the MAC address of the phone into the OnSIP Admin Portal.

You should not use the boot server if you have multiple VoIP providers configured on your phone, as it provides a minimal configuration for OnSIP service that may cause problems for your other providers. is located on our content network at 199.7.172.x. Please ensure that port 80 traffic is available for this address range.
