Question: In a Mission Critical (MC) service, what is the primary characteristic of a simultaneous session on-network, as defined by standards, in relation to media handling between an MC Service Client and an MC Service Server?
Option 1: The client can only send media to one MC service call/session at a time over a single SIP session.
Option 2: The client can receive media from multiple MC service calls/sessions simultaneously over the same SIP session and media bearer(s).
Option 3: The server can only handle one MC service call/session per client, requiring separate SIP sessions for each.
Option 4: The client must use different media bearers for each concurrent MC service call/session.
Explanation: This is correct because a simultaneous session in the context of Mission Critical services allows for the efficient handling of multiple calls/sessions by enabling the reception of media from several sources concurrently, all within the same communication setup (SIP session and media bearer(s)) between the client and server. This enhances real-time communication capabilities, crucial for mission-critical scenarios.
