SIP relies on SDP for session description in multimedia calls; it cannot negotiate media parameters independently of SDP.

When SIP endpoints greatly outnumber H.323 endpoints, you deploy an SC cluster to serve the SIP devices while leaving a standalone SC for the H.323 endpoints.

If SIP registrations are much fewer than H.323 registrations, clustering the SC for SIP isn’t recommended, as the scale doesn’t justify the added complexity.

A proxy SC supports up to 2,000 external soft-client registrations; if you exceed this, you should rebuild it as a proxy-SC cluster to handle the extra load.

In SFU+IAU mode, the IAU’s re-encoded (decoded and encoded) streams are identified by the MpAdaptStrmNo value under Site(18). In the output, MpAdaptStrmNo[2710124429803] is the stream number carrying all three re-encoded video channels.

BFCP transport must match between the MCU and endpoints; if the MCU is configured for TCP, endpoints must also use TCP for BFCP.

The H.26x family (H.263, H.264/AVC, H.265/HEVC) was designed with low-latency, real-time encoding/decoding in mind (ideal for videoconferencing and streaming calls) whereas MPEG-1/2/4 were originally optimized for file-based storage (VCD/DVD), broadcast and progressive streaming. Modern deployments often blend these. For example, using H.265 for both live calls and high-efficiency streaming and newer standards (like H.266/VVC) are now emerging.

The IdeaManager platform is designed for large-scale IdeaHub device management, offering centralized control, remote shutdown scheduling, and batch over-the-air upgrades for fleets of up to millions of devices, including 10,000 ES2 Plus units.

In Manual dual-screen mode on the Box 310/610, you may select Single-screen or one of the two Extended modes (Extended mode 1 or Extended mode 2); Extended mode 3 is not supported.

A SIP response start line is a Status-Line containing the SIP version, status code, and reason phrase - not the method and Request-URI.

In a small- and medium-sized deployment with SMC and SC co-deployed on the same server, a single device supports up to 1,000 concurrent calls.

SSH uses port 22 by default for secure CLI access to the SC admin account.
