This document describes the configuration to be applied to the Yealink CP925 3rd Party SIP Conference Phone for connection to the Alcatel Rainbow Hub solution.
Go to your Yealink extension's web interface, where you can obtain the terminal's IP address directly on the Yealink extension.
Online to the Yealink terminal's web interface using HTTP or HTTPS.
Default login information :
- Login : admin
- Password: admin
Warning: Failure to change the default password exposes the device to unauthorized access, data breaches and fraud, which can compromise the security of the entire network and system. It also increases the risk of service interruption and makes it difficult to monitor and prevent security breaches.

- If you have your own DNS server, please enter it here.
Advanced interface configuration
Go to the Network > Advanced interface
In the Advanced interface, you can configure the port range to be used for the media (voice).
This port range must be authorized by the firewall in order for audio streams to function correctly.
The default port range for media is :
- Start port: 11780
- End port: 12780
Configuring the Features interface

Please note: the time configuration on the terminal is important in order to establish the TLS interconnection between the Yealink terminal and the Rainbow Hub server.
If you don't have an NTP server in your infrastructure, you can apply either a static configuration (by setting a date manually on the terminal) or define an NTP server provided by DHCP or configured manually.
Configuring the Security interface
