GVP for call progress detection

Hello everyone,

Looking for some help here:

We have done a lot of work trying to get answering machine detection working well with Media Server and OCS.

I am looking for what you guys used in tuning so that we can balance efficient AM detection and fast transfer times (Canada has a 2 second requirement like the UK).

So far the only parameters I’ve had luck with are :

machinegreetingduration
maxvoice
voicepause

Any other recommendations?

Thank you!

Wow those are hard…

I’d try

machinegreetingduration = 3
maxvoice = 1 (hello, hi, good evening will not work…)
voicepause = 1

Risk here is many false positive getting customers identified as AM…which would be worst I think

After this you have transfer to agent waiting time

So, the 2 seconds start when? When customer answers? When detected as human and put on Queue?
