Any H.323 video Enables H.323 call
network device signaling to a gatekeeper;
H.323 endpoints can use
gatekeeper services.
Any H.323 video Enables H.323 call
network device signaling (Q.931)
Any H.323/SIP Enables H.323 call control
video network signaling (Q.931), media
device control signaling (H.245),
SIP (TCP) call signaling,
and BFCP signaling.
Ephemeral TCP ports are
used to connect
simultaneous H.323 and
SIP calls.
Any H.323 video Enables H.323 and SIP
network device media (audio, video,
H.224/data RTP) and

Ephemeral UDP ports are
used to connect
simultaneous H.323 and
SIP media calls.
