default value is null.
DISCOVER_AVAYA_ENVIRONM
ENT
Specifies dynamic feature set discovery
Value Operation:
• 1: The phone discovers and verifies if the

The phone sends a SUBSCRIBE request to the
active controller for the Feature Status Event
Package (avaya-cm-feature-status). If the
request succeeds, the phone proceeds with PPM
Synchronization. If the request is rejected, or is
proxied back to the phone, or does not receive a
response, the phone assumes that AST features
are not available.
• 0: The phone operates in a mode where AST
features are not available.
