H.323 Call Signaling Parameter Definitions
(cont’d)
Field Name | Values | Description |
H.323 Version 4 Parameters |
| |
|
|
|
H.323 | Y/N | Signaling for multiple phone |
Multiplexing |
| calls can be carried on a single |
(Mux) |
| port rather than opening a |
|
| separate signaling port for |
|
| each call. This conserves |
|
| bandwidth resources. |
|
|
|
H.245 | Values: Y/N |
|
Tunneling | Description: H.245 messages are | |
(Tun) | encapsulated within the Q.931 | |
| channel. Among other things, the H.245 | |
| messages let the two endpoints tell each other | |
| what their technical capabilities are and | |
| determine who, during the call, will be the | |
| client and who the server. Tunneling is the | |
| process of transmitting these H.245 messages | |
| through the Q.931 channel. The same TCP/IP | |
| socket (or logical port) already being used for | |
| the Call Signaling Channel is then also used | |
| by the H.245 Control Channel. This | |
| encapsulation reduces the number of logical | |
| ports (sockets) needed and reduces call setup | |
| time. |
