If your network is configured for Activation Code Onboarding, your administrator generates and provides each user with a unique 16-digit activation code. The user enters the activation code, and the phone automatically registers.

Activation codes can be used only once, and expire after a certain time. If a user enters an expired code, the phone displays Invalid activation code on the screen. If this happens, the administrator provides the user with a new code.

This feature keeps your network secure because the phone can't register until the user enters a valid activation code.

You can change existing phones to use this feature. To do this, reset the phone to the factory settings. After the factory reset and bootup, the phone registers when the user enters the activation code.

Audio overload point specifies the signal level at which the audio codec is overloaded. For a phone that supports audio performance for 9dB overload point for G.722 codec, you can configure the phone using the Audio_Overload_Point_9dB parameter. Locate the parameter in your phone's configuration file. The default setting is No. For the phones that use ETSI standards and are required to support overload point of 9dB for G.722 codec, set this parameter to Yes. Otherwise, keep the default setting. When set to No, the audio overload point is 3.17dB acrosss the network for consistent power for both the narrow band and the wide band.

Settings example:

<!--  Audio Compliance  -->
<Compliant_Standard ua="rw">ETSI</Compliant_Standard>
<!--  available options: TIA|ETSI  -->
<Audio_Overload_Point_9dB ua="rw">Yes</Audio_Overload_Point_9dB>
<!--  available options: No|Yes  -->

The Audio_Overload_Point_9dB parameter is available for the following phones:
