DNS SRV failover for SIP
In Version 4.3, if multiple SRV records are returned for a given hostname on a SIP DNS lookup, then if the first entry
fails to respond the MCU will try the other entries in the list. This is especially used for SIP registrars, and provides
redundancy in cases where there is an issue with the first registrar location.

Cisco TelePresence MCU MSE 8510 nHD media port mode
Version 4.3 includes a new media port mode, nHD mode, which transmits and receives video at up to w360p
resolution. The advantage of this mode is that a single port license enables two nHD ports; so on a blade with 40 port
licenses you could have 10 Full HD ports, 20 HD ports, 40 SD ports, or 80 nHD ports. This provides a cost effective
way of having large conferences, especially in mass deployments where lower resolutions are regularly used.

To use nHD mode go to Settings > Media ports and select nHD mode from the Media port mode drop-down. A
restart is required for the MCU to start using this mode.
