2.2.3 t120DynamicPortCapability

  • Article

[H245-1.3] section 6, Messages: Syntax specifies an H2250Capability structure. This structure contains a t120DynamicPortCapability field ([H245-1.3] section 7.2.2.4 Multiplex Capabilities). This field allows the client to place a [T120] call to a dynamic transport address instead of the standard well-known port address as defined in [T123]. The H.245 Protocol: Microsoft Extensions do not implement this functionality.

When the H2250Capability structure is sent using the H.245 Protocol: Microsoft Extensions, the t120DynamicPortCapability field is EMPTY (NULL). This field MUST be set to NULL when sent, and MUST be ignored when received. This applies to client and server roles.
