set up dls1 as the collector...
ip sla 1
icmp-echo 172.16.1.10
ip sla schedule 1 life forever start-time now
ip sla 2
udp-jitter 172.16.1.10 5000
ip sla schedule 2 life forever start-time now
ip sla schedule 1 life forever start-time now
ip sla 2
udp-jitter 172.16.1.10 5000
ip sla schedule 2 life forever start-time now
set up an als2 as the responder for device 172.16.1.10 (pc)
ip sla responder
ip sla responder udp-echo ipaddress 172.16.1.1 port 5000
ip sla responder udp-echo ipaddress 172.16.1.1 port 5000
then look at the output...
dls1#sh ip sla stat

dls1#
the icmp output is useful describing successes and failures and round trip time... i don't have a phone set up so the jitter statistics are meaningless, other than no connection.. although, i can see real world usage for this in problematic phone diagnoses... this is very exciting, i know...
word is this is resource intensive so use sparingly...
