Hi: I have been asked to provide some recommendations on how to monitor a network that is going to be used for VoIP. Our network has two main sites (primary and secondary call manager) and multiple remote sites. Want to know if there are some best practices around how the IP SLA should be configured on the routers. I am thinking I will configure IP SLA monitoring on each remote router to both the main sites and IP SLA monitoring between each the two main sites as well. Send a SNMP trap if
one way Jitter > 30ms,
Latency > 150ms,
Packet Loss > 2%
MOS Scores (3.2 - 4.0)
I am planning to use Prognosis to monitor some stuff at the application layer.
