Which statement describes how an H.

An H.248 signaling link connects the Internet Friendly (Edge) Gateway to Avaya Communication Manager (CM) by tunneling H.248 messages using TCP port 2944 and securing them using TLS. H.248 is a protocol that defines how media gateway controllers control media gateways for supporting multimedia streams across different networks, such as IP networks and PSTN networks. An H.248 signaling link is a logical connection between an H.248 controller and an H.248 gateway that allows exchanging H.248 messages for controlling media streams. In an Internet Friendly (Edge) Gateway scenario, CM acts as an H.248 controller and ASBCE DBE acts as an H.248 gateway. To connect an H.248 signaling link between CM and ASBCE DBE, these steps are performed:

CM initiates a TCP connection to ASBCE DBE using port 2944, which is reserved for H.248 over TLS.

CM and ASBCE DBE negotiate TLS parameters and exchange certificates for mutual authentication and encryption.

CM and ASBCE DBE establish a secure TLS session over TCP port 2944.

CM and ASBCE DBE exchange H.248 messages over TLS session for controlling media streams.
