Polycom’s VVX series was a business phone staple for over a decade, but the line has stalled — most models are now end-of-life or approaching end-of-support, with firmware development largely abandoned following a series of rebrands and acquisitions.
If you’re deploying new phones, we recommend Yealink or Grandstream instead — both are actively developed, competitively priced, and fully compatible with SIPcity. Or skip the hardware entirely: our iOS and Android apps deliver the same calling features at no hardware cost.
If you’re sticking with Poly, SIPcity supports VVX handsets through device provisioning and the guides below cover everything you need.
Our Device Provisioning pushes an optimised configuration template to your handset and registers it to a number on your account. It’s the fastest way to deploy a VVX phone and keeps settings consistent across restarts.
Because Polycom doesn’t support zero-touch provisioning, you’ll need physical access to each phone to enter the provisioning address and retrieve the MAC address before the process can complete remotely.
Device Provisioning does not support Polycom IP SoundPoint phones with firmware 3.3 or older. Upgrade to at least version 4.1.1 first — see Upgrade Firmware for instructions.
Step 1: Configure the Provisioning Server

Step 2: Get the MAC Address
The MAC address is the phone’s unique identifier — you’ll need it to link the handset to a number in your account.
Step 3: Register the Phone to a Number
Use this method if you are able to use Device Provisioning. You need four things to complete the setup: your display name, your full DID, your SIPcity account password, and the SIPcity server address.
Enter the settings as labelled in the screenshot:
① Identification
② Authentication
③ SIP Server 1
Presence or Busy Lamp Field (BLF) shows the availability status of extensions on your account as an LED indicator on your IP phone.
BLF operates via the SIP protocol by sending your phone status messages about other monitored extensions. When any monitored extension changes from idle to busy (or vice versa), our Cloud PBX notifies all subscribed phones via SIP NOTIFY messages, acknowledged with a 200 OK response.
We automatically enable Presence and BLF on our network.
Go to Settings > Directories > Contacts Directory.
Select Add (+) and enter the contact details: name, surname (optional), and the full phone number including country and area code.
Set Protocol to SIP (for VVX500 and VVX600 only).
Set Watch Buddy to Enable.
Select Save.
Select the contact, then select Add to favourites to display it on your phone’s home screen.
Give favourite contacts a line extension to simplify dialling (e.g. reduce 1-310-707-504 to 504). This allows coworkers to reach you using a short three or four-digit number.
BLF/Presence support is automatic, but you must separately enable handset presence for manually configured Polycom phones.
Polycom handset volume is typically low and resets to factory defaults, even after manual adjustment. If you’re using our Polycom provisioning, we disable the reset function to maintain your volume settings.
Only the Polycom VVX 600 natively supports Bluetooth. To pair a headset:
On a provisioned Polycom handset, press the Messages button to open your voicemail box.

Older Polycom phones (firmware 3.3.xx or earlier) don’t support web-based auto-provisioning. You may need a two-step firmware upgrade to reach minimum version 4.1.1.
The Polycom’s can only restart the phone from the keypad.
Note: Restarting does not perform a factory reset and will not clear the phone of settings or registered lines.
Note: There is no factory reset option available through the phone’s web interface.
