Question: In an IP Multimedia Subsystem (IMS) with Single Radio Voice Call Continuity (SRVCC), what is a requirement for minimizing transcoding points if this feature is enabled?
Option 1: Both MSC Server and IMS must support either the post-SRVCC or pre-SRVCC transcoding minimization procedure, but not necessarily both.
Option 2: MSC Server and IMS within one network must support both post-SRVCC and pre-SRVCC transcoding minimization procedures simultaneously.
Option 3: Only the MSC Server needs to support at least one of the transcoding minimization procedures; IMS support is optional.
Option 4: Minimizing transcoding points is mandatory for all SRVCC operations, with no option for selective support.
Explanation: To minimize transcoding points in an IMS with SRVCC, the system allows flexibility. If this feature is enabled, at least one of the options (post-SRVCC or pre-SRVCC procedure) must be supported and deployed by both the MSC Server and IMS within a single network, ensuring effective minimization without requiring both procedures.
