Answer Detection

[Guest Michael Rizk]

Dialogic D4/PCI with 5.1.1 and Voice Guide 5.0a (only used for outbound calls)

 

I have a problem when a outbound call is made. VG works fine in making the call but if the line is not answered you would have to assume VG recieves a response of no answer.

 

The problem is that VG thinks the phone has been answered "Live Person Answered" and play's the wav file when it is not supposed to.

 

I have increased the SilenceDetectLevel= in the vg.ini file to 100 hoping to resolve the issue but no luck. Any ideas?

 

The other problem I have is with call escallation as described in the help file. The problem I have is if the first call diverts to a message bank then VG thinks this has been a successfull answer and does not fail over to the second number. The 1st problem also causes issues with this as call escalation will never happen since VG thinks the first call has been answered by a human.

The trace shows that the call was answered by an answering machine 25 seconds after dialing the number, and that 15 seconds after the call was answered VoiceGuide detected end of AM's welcoming message, so it began to play the message designated to be recorded on the Answering Machine.

 

If a call is answered by an Answering Machine then VG treats this as a successful message delivery and escalation calls will not be made.

If it is desirable to make further calls after leaving a message on the Answering Machine then these can be queued from the VG script designated to run when AM answers call - ie. instead of just playing a WAV file specify VG script to run when AM answers, and from within that script queue further calls.

Just to add to this. Found out the first problem seems to be only with mobiles.

 

BTW this is in Australia

[SupportTeam]

Maybe after dialing the mobile number after a while a message is played that 'this number is unreachable' or something to that effect... (or call is in fact actually transferred to voicemail?).

Once a recorded message is heard Dialogic card will assume that a call was answered by an answering machine.

I made sure the voice bank was turned off and tested by dialing manually. There is no obvious sounds during the calling ringing phase.

 

To get around this I installed the new beta3 version and set the AnswerTimeout to 20sec which allows 3 rings instead. Hopefully this will get around my problem.
