How to monitor for VOIP traffic interuptions?

Hi folks,

We've had a couple of occassions lately when our Lync phone system all of sudden will stop sending/receiving external calls. In this case a restart of the Windows server Lync Mediation service restored service.

Our carrier does a "heartbeat" type of session ping every second and I can see the gap in this communication during the downtime. It took a user complaint to detect the problem.

Would anyone know if there is a way at the PA firewall that I could alert when these session pings stop? At 14:12:17 for example?

Hello,

The PAN cannot generate alerts that granular. I would suggest a SIEM alert if you have one. Or a third party monitoring tools such as Solarwinds?

Regards,

@OMatlock,

In this instance I would use something like OSSIM if you aren't looking to spend any money for something capable of triggering alerts for this.
