[Freeswitch-users] Monitoring audio quality

[Valer Nur]

Hi Mike,
If you are interested to achieve real-time improving of the quality (as opposed to passive monitoring) you can try PBXMate. This tool is *NOT* a passive monitoring tool but an active tool. It works like a Sip Proxy and if it encounters a quality issue during a call (e.g. noise and/or low volume) it will fix it in real-time. As a by product the PBXMate also provides statistics on the quality.  You can see one option for integration in the wiki http://wiki.freeswitch.org/wiki/PBXMate-FreeSWITCH-integration

Cheers,

Hi Michael,

Not exactly an answer to your question, but  I have quite a lot of call traffic running over three servers.  I have found the best way to manage this is by using a monitoring tool.  The one I use is http://www.voipmonitor.org/, the actual daemon is open source but you can buy a webUI which uses rrdtool to graph the call quality and display the calls history.  Using a tool like this you can get an idea of call quality for each call.


Cheers,

Ash.
