AMD / CPD Tuning

Hi Guys…

Anyone have already success Tuning CPD/AMD ( Answering Machine Detection )?

i have some issue with AMD some drop not on “Answering Machine” but drop on “SITInvalid”( Phone on condition it is not active ).

Anyone can help for this Condition/Advise ?

hope i’m not wrong insert room… ;D

Thank you and Warm Regards,
GNA.

As first try to describe what is your CPD architecture - where is the CPD executed, what is the used protocol, what did you find out?
