RTPSEND-PCMU(1) User Contributed Perl Documentation RTPSEND-PCMU(1)NAMErtpsend-pcmu.pl - Send an audio file an RTP session as u-law
SYNOPSISrtpsend-pcmu.pl <filename> <dest_addr> [<dest_port>] [<ttl>]
DESCRIPTIONrtpsend-pcmu.pl sends audio files to an RTP session using PCM u-law
(G.711) payload encoding (RTP payload type 0). If no port is
specified, then port 5004 is assumed. If no TTL is specified, then a
TTL of 2 is assumed.
Each packet sent contains 160 samples of audio, and as payload type 0
has a fixed sample rate of 8000Hz, each packet has a duration of 20
miliseconds.
rtpsend-pcmu.pl uses the 'sox' command as helper to transcode and
resample the audio file to u-law, which means that many audio file
formats are automatically supported (AIFF, WAVE, SUN .au, GSM, ...).

BUGS
Doesn't keep packet sending timing very well - it goes out of sync very
quickly.
