H.248 also known as Media Gateway Control Protocol (Megaco), is a gateway control protocol. It is for the control of elements physically decomposed multimedia gateway, which enables separation of call control from media conversion. Though H.248 performs the same functions as MGCP, it uses different commands and processes and supports a broader range of networks. H.248 can operate with H.323 or SIP.

H.248 is meant to address the relationship between the Media Gateway, which converts circuit-switched voice to packet-based traffic, and the Media Gateway. H.248 instructs an MG to connect streams coming from outside a packet or cell data network onto a packet or cell stream such as the Real-Time Transport Protocol.
