Outbound calls

Hi There,

I would like to know if it is possible to create different beepings sound for numbers thats busy or numbers thats discontinued?
1. If the number is busy it should give 3 short beeps.
2. If the number has been discontinued it should give 3 long beeps.

I’m using Elastix 2.0.3, and using a SIP provider for all out bound calls.
