Greetings folks,

I'm currently in the process of trying to put in place better proactive
monitoring of our VoIP environment and I'm hoping to tap into the wisdom of
some of you that have more experience with this than myself.

The challenge that we're running into is that there are simply so many
different things to monitor and it's not something that is on/off or that
relies solely on hardware utilization to fire off alerts. Currently we
typically don't know there is a problem until users report that audio on
their calls is dropping in and out.

Essentially we need to be able to monitor SIP and RTP traffic flow
end-to-end to be alerted when there is jitter or anything else that could
affect call quality. This should include (but may not be limited to):

   - *Internal Network - *Juniper hardware (I've come across some really
   good VoIP monitoring tools like the one available from Solarwinds but they
   require Cisco hardware)

   - *VoIP Servers - *Running Asterisk 1.8

   - *SIP Trunks - *We have limited ability to monitor traffic once it hits
   our SIP trunks so this poses a challenge but it needs to be monitored
   nonetheless


We've set things up like Homer <http://www.sipcapture.org/> and while that
is a great tool for retroactively troubleshooting issues reported it does
not do much to alert us to problems proactively.


Any guidance here would be greatly appreciated. Thanks in advance!


Best,
Evan
