0x01F0 Number of UDP Ports

Specifies the total number of RFC 2833/RTP/UDP ports that the CSP is allowed to open. For a multiport scheme, this number is the number of RFC 2833 channels requested by a host application. Select 0 to specify that only one port needs to be opened that will multiplex all of the RFC 2833 streams. Any value other than 0 implies a multi-port scheme and the actual number of UDP ports required for each RFC 2833 channel basis.
