This target dumps RTP packets into wave files. It currently supports the codecs G.711U, G.711A and G.722. This target need to find a rtp header in the packet it process. A typical rule will look like this :
ipv4.src == 10.1.2.0/24 | udp | rtp
|prefix||dump||Prefix of the files including the path. For example, a prefix of '/tmp/dump' will create files in /tmp and named dump-XXXXXXXX. The prefix supports variable expansion. See File path expansion for more details.|
|jitter_buffer||4000||Size of buffer in bytes to use while waiting for data from the reverse direction. If nothing is received in the reverse direction and this buffer gets full, the RTP connection will be considered one way only.|
