[SIPForum-discussion] QoS measurement

[Jon DiVita]

There are a couple things you could do to measure QoS for VoIP.   You could
use Cisco's IP SLA which basically is a traffic generator that simulates
VoIP calls.  You setup a probe and a responder which then takes quality
measurements.

Also, a lot of SBC's support RTCP  (RFC 3550)  which provide VoIP statistics
within the CDR data.  Alot of useful information within the CDR records with
RTCP data.

Hope this helps a bit.
