Re: [Asterisk-Users] sip/rtp performance monitoring

2005-08-06 Thread James H. Thompson



If the customers are using an ATA or other VOIP device that 
supports RTCP, then you can often get packet loss and jitter stats 
by
extracting the RTCP packets and analyzing them.
This will actually give you the packet loss and jitter that 
the customer is seeing in the received RTP stream from you.
A combination of Tetheral and grep or perl 
can get you along way in capturing and analyzing this data.

  Subject: [Asterisk-Users] sip/rtp 
  performance monitoring
  I'm currently running asterisk to provide VoIP services to 
  clients of the ISP I work for.I would like to be able to tell if I 
  am loosing packets and/or are having other issues with any of the voice 
  streams, so I can address them proactively.I'm not particularly 
  interested in spending oodles of money buying one of the commercial 
  analysis tools. Is there some open source tool (or something I 
  can monitor in asterisk) which will tell me if I'm missing packets or 
  similar? I realize this will likely be only from the customer 
  towards me since I can't really monitor at the customer 
  end.-forrest___Asterisk-Users

You could use Ethereal.  It has an RTP tool that tells what the jitter 
and packet loss is.


And by the way, if your customers have Sipura units then you can indeed 
monitor their end as well.  The latest firmware versions include a 
feature where they send all call statistics(jitter, packet loss, ..etc)  
in a header with the BYE message.  We have integrated it into our system 
so when our support people open up the customers account, then can click 
on a link to see all the RTP stats of all calls made and received by the 
customer.  Its quite nice and quickly gives a snapshot of the quality of 
service the customer is receiving.
