I'm currently writing an IVR Script, and I want to know if it is posible to change the Prompt audio format from CCITT u-law 8 KHz, 8Bit, Mono 7 kb/sec, to another format like GSM 6.10, and still be playable from the IVR.
Or if there are any cisco java classes that I could call from my IVR script to change the audio format of a file from GSM to CCITT u-law? Or a third party tool CLI that could do the trick that you recommend?
