Hi all :-)
It's explains in sipp documentation how to send an rtp flow by an exec
command :
Below an extract from sipp documentation
/*RTP streaming*//allows you to stream audio from a PCMA, PCMU or
G729-encoded audio file (e.g. a .wav file). The "rtp_stream" action
controls this./
//
* /<exec rtp_stream="file.wav" /> will stream the audio contained in
file.wav, assuming it is a PCMA-format file./
* /<exec rtp_stream="[filename],[loopcount],[payloadtype]" /> will
stream the audio contained in [filename], repeat the stream
[loopcount] times (the default is 1, and -1 indicates it will repeat
forever), and will treat the audio as being of [payloadtype] (where
8 is the default of PCMA, 0 indicates PCMU, and 18 indicates G729)./
* /<exec rtp_stream="pause" /> will pause any currently active playback./
* /<exec rtp_stream="resume" /> will resume any currently paused
playback./
I use it in my invite scenarios and it works very well !
But i don't find any commands for to indicate to sipp to capture rtp
flow which comes from other side.
However, there is a command for echoing an rtp flow from a source to
this source for to avoid usage of a local sound file.
/*** RTP behaviour options:
-mi : Set the local media IP address (default: local primary
host IP address)
-rtp_echo : Enable RTP echo. RTP/UDP packets received on port defined
by -mp are echoed
to their sender.
RTP/UDP packets coming on this port + 2 are also echoed
to their sender
(used for sound and video echo).
-mb : Set the RTP echo buffer size (default: 2048).
-mp : Set the local RTP echo port number. Default is 6000.
-min_rtp_port : Minimum port number for RTP socket range.
-max_rtp_port : Maximum port number for RTP socket range.
-rtp_payload : RTP default payload type.
-rtp_threadtasks : RTP number of playback tasks per thread.
-rtp_buffsize : Set the rtp socket send/receive buffer size/
It could be insteresting but i don't test it. I would be insterested by
an evolution of sipp, with a specific command in xml script file, or a
way for saving a rtp flow sended by a distant source ( an another sipp
instance for example) to a local file.
Is there a way for to do this ?
Thanks for yours responses...
