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.

Avaya Breeze® is a development platform that enables rapid development for applications targeted to meet a customer’s communications needs. It is used by Avaya, Partner, and third-party developers to create and deploy snap-ins, which are modular software components that provide specific functionality or features. Avaya Breeze® allows application developers to quickly add new capabilities to their Avaya solutions, such as voice, video, messaging, presence, collaboration, and analytics.

Avaya Aura® Presence Services uses different ports for different purposes. Port 5222 is used by endpoints like Avaya one-X® Communicators, Avaya Equinox®, or Avaya IX™ Workplace to establish client-to-server XMPP connections with the Presence Services snap-in on the Avaya Breeze® server. Port 5269 is used for server-to-server XMPP connections with the third-party XMPP servers, such as Google Talk or Jabber. These ports enable the presence and instant messaging features for the users34
