Wavelink Avalanche Server

Wavelink Avalanche Server Overview

This chapter describes the Wavelink Avalanche Management Console and how to use it to configure the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G. The Configuration Utility (CU) for Wavelink Avalanche can be installed on the Wavelink Avalanche Management Console and used to configure a single phone or multiple phones with common settings.


Note


The phones do not support Traffic Stream Rate Set (TSRS) or Cisco Compatible Extensions (CCX) V4.



Note


Not all features can be configured using Wavelink. Some features can only be configured from Cisco Unified Communications Manager Administration.


Before You Begin

Before you can use the Wavelink Avalanche Management Console to configure phones, ensure that you have the necessary components and follow the best practices during your setup.

The following components are required for configuring the phone using the Wavelink Avalanche server:

  • Wavelink Avalanche software:

    • Avalanche Manager Agent

    • Avalanche Management Console

  • Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Firmware Release 1.3(1) or later

  • Configuration Utility (CU) for Wavelink Avalanche

  • DHCP server

  • Cisco Unified Communications Manager

Best Practices

This section describes the best practices recommended for setting up and using the CU on the Wavelink Avalanche server.

  • Ensure that the phone is registered to Cisco Unified Communications Manager.

  • Try out this process with one or two phones before deploying to many phones.

  • Set up a VLAN that has access only to the Wavelink server.

  • Configure DHCP Option 149 with the Wavelink server IP address. If you do not configure this option, see Set Up Wavelink Server Address from Phone.

  • Configure a Cisco Access Point to use a default SSID of "cisco" with open authentication and no encryption.

Wavelink Server IP Address Setup

If you did not configure DHCP Option 149 with the Wavelink server IP address, you must manually assign it.


Note


Do not perform this task if you previously configured the Wavelink server address using DHCP Option 149.
