nonstandard: Nonstandard compatible compression format.

rtp-connections number1: The number of RTP compression connections, in the 
range 3 to 1000. By default, the number of RTP compression connections is 16.

tcp-connections number2: The number of TCP compression connections, in the 
range 3 to 256. By default, the number of TCP compression connections is 16.

tcp-include: Includes TCP header compression when performing RTP 
compression.

Use the fr iphc command to enable IP header compression function, including 
RTP/TCP header compression.

Use the undo fr iphc { nonstandard | tcp-include } command to disable this 
function.

Use the undo fr iphc { rtp-connections | tcp-connections } command to 
restore the default compression connection numbers of RTP and TCP.

By default, number1 and number2 are 16.
