[VoiceOps] VoIP passive monitoring appliances or software - any recommendations?

[Michael Krüger]

Hello Brian,

of course I would recommend our own solution for passive monitoring. 
Have a look at www.voipfuture.com, or get in touch with eyal.ullert at voipfuture.com .

Some highlights:

High performance probes scaling for up to 10Gbit/s tapped network links, based on standard HP servers
More than 120k concurrent media streams per second analyzed
Fixed 5-second time-slices reporting media quality for every media stream
Correlation of media streams with SIP signaling
Statistics that can be used for SLA agreements with enterprises 
Over 400 KPI values and metrics that can be used for quality based routing or fast troubleshooting 
Web based user interface to access measurement data from any browser. No client Java dependencies.
Economic database cluster based on PostgreSQL scaling to a multi tera-byte data warehouse if needed, while saving customers reoccurring license fees
Interfaces to integrate quality metrics to CDR/billing applications, customer care centers, etc...

Let me know if you have further questions.

Regards,
Michael

If the customer uses our routers to terminate their SIP session, we can pull call quality stats from those routers as well.  We can also use our own office telephones to make and receive test telephone calls, and we can of course run Wireshark captures from the switches to which those phones are connected.

The peering link is connected to a Cisco 12k router on our side, so there is no way (afaik) to mirror the port, as on a switch.

It will need two network interfaces; one connected to a management network, the other a capture interface.  The capture interface will connect to a network tap, and the network tap connected in-line between our router and the patch panel.

Given the usual details - calling number, called number, date and time - we want to be able to quickly inspect traffic and dig into the details of the stream.  Do we see any missing packets from the media stream?  What is the MOS score of a particular call?  Do we see any missing packets coming from us?  Any missing packets from the provider?
