Plz Help me in detecting the answering machine , the plum server never returns the answering Machine status or parameter while calling. It returns the parameter as 'Voice' , even if the answering machine is enabled and the customer didnt pick up the phone. Please help me in this.
The outbound IVR system no longer attempts to differentiate between voice and answering machine. We are working to implement a new callee_type detection algorithm to replace the old algorithm which had proved at best to be only marginally effective.

WIll this upgrade in answering machine detection affect the initial delay that occurs when an outbound call is made?
At present, we're observing between a 3 and 4 second delay between the call being answered and the first voice prompt being provided to the user. In our pilot, many users thought that they had a bad connection and hung up when they didn't hear anyone on the other end after 3-4 seconds.
Plum recently reintroduced an improved callee type detection algorithm to the outbound IVR system. It can differentiate between voice, answering machine and fax (however, not with 100% accuracy). This is responsible for the current delay of 3-4 seconds. We are currently looking into reducing this delay as much as possible while maintaining our high reliability.
Hope This Helps,
Plum Support

While you are investigating ways to reduce the delay, is their a programatic method for disabling answering machine detection so as to eliminate the delay. During our prototype testing, users found the delay entirely unacceptable.
Yes, there is currently a way for us to disable this on a per account basis. Please send an email to support@plumvoice.com with your account information and they will disable callee type detection. Once the new faster version is available an email will be sent to all customers who have the current generation of callee type detection disabled to give them the opportuntity to try out the new IVR system.
