Polycom skype for business questions

Hi, can anybody help me with these questions?



    • What protocol does the Polycom use to register to the cloud (i.e. is it https? Sip? H323?)
    • How does call setup happen from the source (are there new TCP/UDP streams opened (i.e. a new connection is started)?
    • How does a call look to the destination polycom (any new sessions created)?
    • When video is utilized what protocol is this (does it keep the HTTPS session or create a new RTP session?  What is the packet rate for video?)?
    • Are the packets from the Polycom tagged with the appropriate DSCP value and kept end to end (will need a packet capture)?
    • If an on-net Polycom calls another on-net PolyCom (like NYC calls DC) does the traffic go off-net or directly from one device to the other utilizing internal networking?
