Your IOS probably requires the rtr commands. Can you try typing
rtr <operation num>
You can read about configuring the udp jitter operation at
Just make sure you specify the codec.
What is the full version of your IOS?
If you look at the cisco feature navigator http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp and look by the name of your imag, that should tell you what type of IP SLA operations it supports.
#1 cisco 2620XM - c2600-ik9s-mz.122-46.bin
#2 Cisco 2851 - c2800nm-ipvoicek9-mz.124-15.t1.bin
#3 2851 - c2800nm-ipvoicek9-mz.124-15.t1.bin
I am not sure if I am going about this correctly but essentially I am creating a two way conversation between all three devices. So, I end up with six call paths.
#1 to #2 I am getting no data.
#1 to #3 I am getting no data
#2 to #1 I am getting good data
#2 to #3 I am getting data but it says that I am having 50% packet loss and not sure if that is correct.

I am getting closer to what I would expect that I want. I am not sure that I believe the 50% packet loss stat. Any suggestions.. I am open ears. I am learning quite a bit about VoIP with this project.. and the configurations associated with IP SLAs but I dont know near enough to be confident of what I am doing.
Is it possible that VoIP Monitor is only supported in situation where the router was set up using the IP SLA commands? One my one node where I had to use the "rtr" commands, it appears to be running but from Orions point of view I get an event that says:
Error "Specified operation does not exist on the router." occurred during polling VoIP Call Path router-rtr01.company.com->other-router (simulation node router-rtr01.company.com [IP ADDRESS])
I used the command reference tool that was suggested and searched on my specific IOS version however it states to use the "IP SLA" command.. There is no such command in my IOS..
