The AIWS (Avaya In-Building Wireless Server) unit supports several functions:
It allows SMS messaging between handsets.
It also allows wireless software upgrades and configuration of the handsets. Without an AIWS, handsets can only be upgraded and configured when in an advanced charger or a rack charger.
For IP Office R5, the AIWS provides directory integration between the IP Office and the Avaya Wireless DECT system.
This requires the IP Office security settings to allow TFTP Directory Read ().
On Linux-based IP Office servers, the must allow access using port 69.
For IP Office R6 and higher, the master base station does directory integration when an AIWS is not present. However, if SMS is required, the AIWS is used for both functions.
The unit is managed using a web browser and requires a fixed IP address.
