How to – Decrease SDP(short duration percent) in ViciDial

There is a new feature in ViciDial as of SVN 3878 that will allow you to increase the call handle time through the AMD system which would lower your Short Duration Percent(SDP) in your carrier stats. Doing so can typically save you hundreds if not thousands per month in VoIP fees for being below their SDP requirements. Adding one line to you carrier dialplan as show below will do this for you. Doing so will also save your DID’s (Caller ID’s).

This example will add 7 seconds to each call.

exten => _8567.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _8567.,n,Set(__AMDMINLEN=7)
exten => _8567.,n,Dial(SIP/carrier/${EXTEN:4},,tToR)
exten => _8567.,n,Hangup

I hope this helps
