The Avaya Aura architecture defines authentication as the process of verifying an identity which may belong to a user, an application or system.
The Avaya Aura Architecture’s Session Manager provides the SIP Registrar/Proxy function referred to in this section. Devices connecting to a SIP Registrar/Proxy can be divided into two categories:
Un-trusted: The SIP Proxy/Registrar will NOT accept PAI from devices in un-trusted realm. Any entity or device not identified in the SIP Registrar/Proxy’s trusted host list falls into this category.
Trusted: The SIP Proxy/Registrar will accept PAI from trusted entities or devices. A trusted device is also referred to as a trusted host. To be trusted there must be a corresponding entry in the SIP Registrar/Proxy’s trusted host list. To identify trusted hosts, the following authentication mechanisms will be applied.
