RDP session to what?
What are you looking to test?
You can surely do reactive script debug on any windows machine as long as you can call into the script, i.e. via PSTN.
I can't call the script so I'm thinking I need to use IP communicator or something to call it and run a debug. But there's no audio on an RDP session, so hearing announcements is out of the question.
I was looking for a suggestion or creative way to test a script. Maybe there isn't one.
I see, if there is no way to call into it, it would be impossible to test it. If you have access to the GW and proper dial plan is configured you could use csim to make a call, but that is not very reliable.
