If a static NAT service is installed between UNIStim phones and Avaya Breeze® servers, the phones are unable to register in the system by default. As part of the registration process, the Device Adapter redirects the phones to local IP addresses used by the appropriate Avaya Breeze® platform nodes. The phones cannot reach these IP addresses from the outside network.

From Release 8.1.4, the Device Adapter provides a configuration option to enable the mapping of local to public IP addresses. The mapping enables support for configurations with static NAT services.
