Polycom IP and VVX Configuration Guide
Updated over a week ago

This article describes the configuration of most Polycom phones of VVX and IP series. The only difference would be the lack of some features or some extra features that don’t affect registration.

From the Web GUI go to -> Settings -> Lines -> Line 1 Identification

  • Display Name = what will be displayed

  • Address = Extension

  • Authentication User ID = found in the WebPanel

  • Authentication Password = SIP Password found in the WebPanel

  • Label = Extension

  • Third Party Name = Extension

  • Number of Line Keys = 4 (the actual number depends on the model)

  • Calls per line = 1

  • Ring Type = that’s the sound of the ring.

IMPORTANT: The Polycom phones have a known bug: only ring types 1-13 (except for the splash ringtone (#10) and 15 work correctly.

Under Outbound Proxy

  • Address = Outbound Proxy (Mightycall proxy, in most cases :16060 string is not needed, but it needs testing)

  • Port = 16060

  • Transport = UDPOnly

Under Server 1

  • Address = SIP Domain (Mightycall proxy, in most cases :16060 string is not needed, but it needs testing)

  • Port = 16060

  • Transport = UPDOnly

  • Expires = 300

  • Retry Timeout = 0

  • Retry Maximum count = 3

  • Line Seize timeout = 30

NOTE: some models may prefer Expires set to 180 though 300 is deemed to be the correct one.

Under Message Center


Subscription Address = Actual Extension as in the Address field above
Call Back Mode = Registration

From the Web GUI go to > Settings > Network > NAT

  • NAT Keep Alive = 20 seconds

From the Web GUI go to > Settings > SIP > Local Settings

  • Local SIP Port = typically, are used ports 16000, 16001, 16002, etc. Do not assign ports below port 1024.

  • Calls Per Line Key = Leave Default

  • Type = Private.

If the phone is brand new, has never been configured yet or was hard reset, then proceed with the following step:

From the Web GUI go to -> Settings -> SIP -> Local Settings -> Digitmap


Enter the following to support Ext Dialing (Only enter the one that applies to your Ext numbering):


• For 3digit extension: 011xxx.T|1[2-9]xx[2-9]xxxxxx|[2-9]xx[2-9]xxxxxx|[2- 9]xxxxxxT|0T|*xx.T|[2-9]11|1[01]x|xxxT|9xxxT|*99xxx
• For 4digit extension: 011xxx.T|1[2-9]xx[2-9]xxxxxx|[2-9]xx[2-9]xxxxxx|[2- 9]xxxxxxT|0T|*xx.T|911|[2-8]11T|xxxxT|*99xxxx
• For 5digit extension: 011xxx.T|1[2-9]xx[2-9]xxxxxx|[2-9]xx[2-9]xxxxxx|[2- 9]xxxxxxT|0T|*xx.T|911|[2-8]11T|xxxxxT|9xxxT|*99xxxxx
• For 6digit extension: 011xxx.T|1[2-9]xx[2-9]xxxxxx|[2-9]xx[2-9]xxxxxx|[2- 9]xxxxxxT|0T|*xx.T|911|[2-8]11T|xxxxxxT|9xxxT|*99xxxxxx

From the Web GUI go to Preferences -> Date and Time


• Under display format, choose the format to display (default is 12 hours).
• Under Time Synchronization, choose your time zone and the SNTP server of your choice. Though it doesn’t look like one, it is an important step, as sometimes registrations issues are merely caused by the timezones not synchronized.

Don’t forget to click Save button on each page!

After all these settings are good, the configuration is done. The phone will restart itself. Do not unplug the phone from the power while it's restarting. The phone may restart several times – do not interrupt this process.
