NAME

       rtpsend-pcmu.pl - Send an audio file an RTP session as u-law


SYNOPSIS

       rtpsend-pcmu.pl <filename> <dest_addr> [<dest_port>] [<ttl>]


DESCRIPTION

       rtpsend-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.
