I've setup an udp-jitter operation with codec g729 on a cisco 1761 to run on port UDP 51140 (destination) and an ip sla responder on the far end side. I see that control packets are received and get a MOS and ICPIF value as well as RTT. But I do not get any value for latency. It is always 0.
First I noticed that ntp was not in sync but this is ok now but still no luck.
this is the topology:
c1761 - ASA - Internet - ASA - remoteRouter(c38??)
both sides are running IOS from the 12.4T train (I currently have no access to check exact version). I have no access to the config on the ASA (and the Internet :-) ) but according to the reponsible person there is no ACL to restrict any traffic (ip permit). Connection is done through an IPSEC tunnel.
What can prevent the latency to be calculated? (I assume ASA is doing stateful inspection)
