Avaya 77201X Exam With Confidence Using Practice Dumps

In Avaya IP Office Server Edition, multiple servers (Primary, Secondary, and Expansion systems) communicate with each other to form a unified system. The protocol used for this inter-server communication is the Small Community Network (SCN) protocol, making Option C correct. SCN is a proprietary Avaya protocol that enables features like distributed hunt groups, call routing, and resilience across servers. Option A (H.323) and Option B (SIP) are VoIP protocols used for call signaling with endpoints or trunks, not inter-server communication in Server Edition. Option D (SNMP) is a network management protocol, not used for server-to-server coordination.References: Avaya IP Office Server Edition Reference Configuration Guide, SCN Configuration Guide.

IP Office supports up to 128 simultaneous conference channels (Option B), allowing multiple conference calls with a total of 128 participants across all conferences. This requires sufficient hardware and licensing. Options A, C, and D exceed or fall short of this limit.References: Avaya IP Office Conference Configuration Guide.

Call Intrusion (Option A) allows a user to join an active call (e.g., for supervision) using a feature code, subject to permissions. Option B answers ringing calls, Option C records calls, and Option D redirects calls—none involve barging in.References: Avaya IP Office Feature Code Guide.
