How Do I Gain Access to CISCO 8851 Phone Advanced Settings

[Williams Chapel Church]

We bought 5 CISCO 8851 VOIP Phones to use at our church. I am familiar with VOIP phone, but somehow cannot gain access to the Advanced Settings Tab.

Help...I need to get these manually provisioned to RingCentral's Network.

Thanks

To use a third-party call manager with your IP phone, you must first convert the phone's firmware to Multiplatform MPP. Once the firmware has been converted, you can access the phone's administration web interface using the IP address that the phone has been assigned.

For more info about how to convert Cisco IP Phone to MPP firmware please check the below document:

There are two options: 

1.  Convert the phones, from Enterprise image, to 3PCC/MPP image (L-CP-E2M-88XX-CNV).
2.  Manually integrate the phones to RC using known working SEPmacaddress.cnf.xml files.

If you bought an enterprise phone, check with the vendor if there is an option to replace it   with MPP version phones. To convert an  enterprise phone to  MPP (Multiplatform Firmware ) you need  license.

Else go with option 2 mentioned by @Leo Laohoo to register with RC
