Change a Poly VVX or CCX Phone from Teams to Generic SIP

This article explains two ways to change a Poly VVX or CCX phone from the Microsoft Teams profile to the Generic SIP (Open SIP) profile using:

1. The phone’s screen (GUI)
2. A web browser

Method 1: Change the Profile from the Phone Screen (GUI)

This works when the phone menu is accessible and not locked down.

Steps

1. On the phone, press Home.
2. Go to Settings.
3. Select Advanced.
4. Enter the admin password.
   • Default: 456
5. Go to Administration Settings.
6. Select Base Profile.
7. Choose Generic (or Open SIP, depending on firmware).
8. Accept the prompt to reboot.
9. Let the phone restart and re-provision.

Notes

• The phone will reboot automatically.
• If Base Profile is missing, the phone may be locked to Teams.
• If the phone is locked to Teams, you may need to perform a factory reset to regain access.

Method 2: Change the Profile via Web Browser (Phone Web UI)

This is useful if you manage phones remotely and the web UI is enabled.

Prerequisites

• You know the phone’s IP address.
• The web interface is enabled on the phone.
• You have admin credentials.

Steps

1. Find the phone’s IP address:
   • Home → Settings → Status → Network
2. Open a browser and go to:

   http://<phone-ip-address>

3. Log in as Admin:
   • Default password: 456
4. Navigate to:
   • Settings → Provisioning → Configuration
   • or Admin Settings → Base Profile (menu varies by model)
5. Set Base Profile to Generic.
6. Save the change.
7. Reboot the phone.

After Reboot

• The phone switches from Teams to Generic SIP.
• SIP firmware and provisioning will load next.

Common Issues

Base Profile option is missing

• The phone may be locked to Teams firmware.
• You may need a factory reset to regain access.

Phone reboots but stays in Teams

• Your provisioning server may be forcing Teams mode.
• Check for a base profile setting that forces Microsoft/Teams (for example: device.baseProfile="Microsoft") and remove it if present.

Cannot access the web UI

• The web interface may be disabled.
• Enable it via provisioning, or use a factory reset if you cannot access admin settings.
