Through a combination of flexible requirements and recommended concentrations, Red Hat is providing a path for professionals to advance their careers and for its subscription customers to find the right architect.
Standard Local Survivability (SLS) is a cost-effective alternative well suited to a branch location that does not have sophisticated telephony needs. In contrast to the server-based survivability features, SLS operates entirely from the H.248 Branch Gateway and requires a data set comprised of CM translations (survivable ARS analysis and configuration data). When you log into a H.248 Media Gateway via CLI you have likely noticed the screen message “Survivable-call-engine is disabled.” Let’s take a look at what this means.

Session Initiation Protocol (SIP) is an internet signaling protocol, developed by the IETF (starting in 1996), for establishing, maintaining, and tearing down sessions between a variety of real-time media, including voice, video, and chat. SIP allows endpoints to locate other endpoints, whether stationary or mobile. SIP doesn't have to worry about transporting voice or video as Real Time Transport Protocol (RTP) takes care of that. It also relies on Session Description Protocol (SDP) to negotiate capabilities and codecs. SIP does not provide a Directory Service or Authentication, but it does work with services such as LDAP or RADIUS. SIP is only concerned with signaling. This white paper is going to look at the way SIP is used in the converged Unified Communications environment.
