IMS-MGW - IMS Media Gateway

In the 3GPP IMS (IP Multimedia Subsystem) architecture, the IMS-MGW operates in conjunction with the MGCF (Media Gateway Control Function) in order to support interworking between IP based transport networks and the circuit switched domain. The IMS-MGW will translate media arriving within a TDM based timeslot to an RTP (Real time Transport Protocol) stream or vice versa.
