I use a call flow where the customer is able to record a message. When the customer records a message and disconnects the line i use the disconnect handler flow to email the message (wav file) anyway (many customers forget to decent close the recording) . There is one problem: when the customer disconnects before a wav file is recorded and before another customer lefts a message, the previous wav file is send by email again for the second time. In the VAD i simply removed the wav file when it existed before starting a recording. The new CFD uses C# scripts. Can you give me an exampe of a C# script to remove a file ? Or can you add "remove file" to the "Read/Write to file" (Advanced Options) ??
