Hi Rachid,
per my understanding the H.460 is used for H.323 endpoints only. Plus the ports details you can find below
For connections to the VCS Expressway using the Assent protocol, the default ports are:
Call signaling
• UDP/1719: listening port for RAS messages
• TCP/2776: listening port for H.225 and
H.245 protocols Media
• UDP/2776: RTP media port
• UDP/2777: RTCP media control port
For connections to the VCS Expressway using the H.460.18/19 protocols, the default ports are:
Call signaling
• UDP/1719: listening port for RAS messages
• TCP/1720: listening port for H.225 protocol
• TCP/2777: listening port for H.245 protocol
Media
• UDP/2776: RTP media port
• UDP/2777: RTCP media control port
• UDP/50000-52399: demultiplex media port range
The media ports used is mostly dependent on the endpoint sending the media. if the endpoint is capable of sending Multiplexed media it is always prefered.
if the endpoint is not capable of multiplexed media it will use different ports. range varies with different endpoints.
Thanks
