FLX – VoIP  Registering with Avaya IP Office 500 
Date: April 5th, 2012 
This technical note gives a detailed description on how to register a Revolabs FLX conference phone with 
Avaya IP Office 500 PBX. On the IP Office a SIP extension and user has to be created using Avaya IP 
Office Manager. Once that user is created, the FLX can be set up to register with the Avaya IP Office 
PBX. 
To perform the tasks described in this document, the user needs to have administrative rights on the IP 
Office. While the steps in this document are not difficult, we recommend that a trained IP Office PBX 
administrator perform these tasks. 
The instructions and screen shots provided here were prepared using Avaya IP Office R7 Manager, 
Version 9.0 (23); other versions of the IP Office manager may differ, though the general procedures are 
the same. 
Configuring Avaya IP Office for FLX Registration 
To prepare the Avaya IP Office for the FLX Conference phone, a new user needs to be configured on the 
PBX. This step is required for any third party SIP device. 
To add a user and extension: 
1. Start the Avaya IP Office R7 Manager and 
login. 
2. In the IP Offices panel on the left side, expand 
the item for your IP Office, right click on User, 
and choose New.
