[cisco-voip] LUA Scripts

[Matt Slaga (AM)]

That will probably be hard to come by.  TAC doesn’t support LUA scripts in UCM, they will defer you to the Cisco Developer Network for assistance.  The link below is the developer guide for SIP transparency and normalization.  It does not have any detail on load or process time.

Thank you Anthony for sharing your experience. The access violation condition, do you know of a document that describes the threshold/limits etc before it stops processing the script.
I know that the impact would depend on the type of script also, but let's say if we have a script that inspect every invite on a sip trunk and modifies a header. We could have thousands of invites in a few hours during business and I am just wondering if there is an easy way to see how much cycles a script would use.

I have created one and no, there is not. In fact, the feature implementation prevents an impact to system resources and terminates your application if there is a violation in that regard. I know this because the logs kept saying that some resource limit had been exceeded because of my sloppy code, which was looping infinitely on me. :)

Take my case as you will, as I cannot give you specifics on the size of this implementation, other than saying it wasn't very large. Kind of medium-ish, maybe even on the extra-medium side.

Has anyone using LUA scripts seen any impact on CPU or memory utilization?
