Vg Playback Response Slow

[joelyang]

Hi,

 

We experienced a problem. When a call comes in, VG will play a sound file asking caller to enter identification numbers. Sometimes, this happens immediately after caller says "hello". but sometimes, VG will play after 1 to 3 seconds later and sometimes never play and hangup. Does this erratic response have to do with background noise on a busy street? We have callers calling from everyway like home, office, pub, streets, etc. We are using Dialogic D/41JCTLS.

 

Thanks.

I take it that these are outbound calls - ie: VG is dialing a person.

Does this erratic response have to do with background noise on a busy street?

That can be the reason - see: http://voiceguide.com/forums/index.php?showtopic=1269

 

If you use Digital ISDN lines (T1/E1) then the 'call answered' event is sent to VocieGuide immediately when call is answered - and if you do not have to detect whether call is answered by answering machine or human then this is probably the best way to go.

 

An even if you do have to detect whether call is answered by answering machine or human then ISDN still works better overall then Analog lines as at least the system knows exactly that a call has been answered - so the detection of what is happening on the line can be made a bit more accurately.

Yes. It is outbound call. We do not need to distinquish answering machine or human voice. How do we remove this detection feature?

 

Thanks.

We do not need to distinquish answering machine or human voice.

I'd definitely recommend going to ISDN then...

 

I understand you can specify:

 

IGNORE

 

in the "Message to play when answering machine answers the call"

 

you can also try using:

 

DISABLE

[joelyang]

Where can I set this? In which VG module or Dialogic card?

Thanks

[joelyang]

I guess you are referring to VG Telephone Loader. How do we set DISABLE or IGNORE if we use vb script?

[SupportTeam]

See VG.INI file, section [VGDialer] :

[VGDialer]

 

....

 

;If Dialogic cards are used they will detect if an answering machine answers the call.

;To Enable Dialogic's answering machine detection set AM_DetectionMode to "Enabled"

;To Disable Dialogic's answering machine detection set AM_DetectionMode to "Disabled"

AM_DetectionMode=Enabled

[joelyang]

Thanks. Will try this.

[joelyang]

DISABLED

and

IGNORE

work well.

DISABLED

played sound file immediately after dialing while

IGNORE

played only after outbound call has been answered. This solved our problem of playing sound file when outbound call is answered.

 

We have another problem. When background noise is high, "Capture Entered Number" module cannot detect numbers (not even DTMF) and keep playing back the sound file. Is there any solution to this?

 

Thanks.

Hi,

 

Below is the log for the problem mentioned above. The numbers entered were ignored or not recognised when there is a background noise. Even the key * and # is not recognised. The sound file keep playing until the number of playback times is reached.

Please help. Thanks.

The numbers entered were ignored or not recognised when there is a background noise.

The background noise must have been pretty loud... or that phone does not send the DTMF tones very clearly Is it a mobile? some mobile networks have poor sound quality which would affect DTMF detection if there is other background noise on the line.

 

There is really nothing that can be done to alter the DTMF detection settings.
