Folks,
Thats what RAQMON doesin a media gnostioc fashion.
RAQMON is an excellent approach for network elements
The media statistics for SIP calls are intended at
the application level in
endpoints, such as when using an Instant Messenger
client for voice or a
soft phone, or a SIP phone, or a game with VoIP.
Let's not be dogmatic and force techniques that have
been designed for
network elements such as routers, gateways or
servers on to the application
level in endpoints, where many good practical
reasons have shown the RTCP
extensions to be the better approach. Live and let
live!
Thanks, Henry

Like you point out its not SIP specific but there
are certain aspects of SIP
that we need to take care of and RAQMON does that.
let me clarify; Since it
is SIP the session monitoring is media agnostic and
need to accomodate that.
Thats what RAQMON doesin a media gnostioc fashion.
Voice Over IP, Video over IP or Fax over IP and many
other apps fit into the
Framework. See it helps you.
Since it is in WG LAst call, would be very happy to
see what kind of needs
you have and ensure that it serves the purpose.

I agree. This is not a SIP domain specific issue.
See my previous answer
pointing to the real-time application QoS monitoring
(RAQMON) work in the
RMON MIB WG.

I don't think that's really a SIP domain issue,
though
this may have
been adressed somewhere that I'm not aware of.
If you're using RTP to carry the audio than these
statistics are
derived from the RTP stream in the context of the
sender
(with you being the
receiver) and the sender sends SR (Sender Report)
RTCP packets with
interarrival jitter included. Packet count,
fraction lost,
and cumulative
number of packets lost are also transmitted in
these packets.
Latency would
probably be derived from the NTP timestamp if
anything and is
not directly
addressed in RTP to my knowledge. So if you wanted
this data
after the fact
the server would have to maintain that
information, and it
would probably be
a query at the application level, not really
anything to do with SIP.

Is there any way by which I call query a SIP
endpoint for
media statictics after call termination. I would
like to know
details like Jitter, latency, packet loss,
packets received,
packets sent etc.
Thanks in advance.
