Mw
Correct Answer
C. MgExplanation
The interface between the Serving Call Session Control Function (S-CSCF) and the Media Gateway Control Function (MGCF) is represented by "Mg". This interface is responsible for the exchange of signaling and control information between the S-CSCF and the MGCF in a Voice over IP (VoIP) network. The MGCF is responsible for controlling the Media Gateway (MGW), which handles the conversion of media streams between the IP network and the traditional Public Switched Telephone Network (PSTN). The S-CSCF, on the other hand, is responsible for call session control and routing in the IP Multimedia Subsystem (IMS) network. Therefore, the "Mg" interface facilitates the communication and coordination between these two functions.Rate this question:
