Hi thatnks for your response. I use a 1760 h.323 gateway. In the priveledge mode, the command "csim start" is not there and when I do a question mark at the priviledge mode, I dont see the option "csim start".

Peter,

its a hidden command.

just type in csim start < directory number u want to call> and hit enter, then see what happens

I tried it but got the output below:

"

Router#csim start 1003

csim: called number = 1003, loop count = 1 ping count = 0

csim err:csim_do_test Error peer not found

Router#

what that means is that you do not have a voip dial-peer that is responsible for routing the called number..

you need to have a voip dial-peer that will route the call...

I want to add that this should NOT be used in any sort of formal testing. csim start does not make a proper RTP stream and therefore negotiations of certain protocols will throw errors that aren't real, seeming like links and connections aren't working, when they actually are! (i.e. try csim start over a QSIG T1 and watch it fails with random error's! )

Cheers,

Chad
