Disconnect Tone Leave Over At End Of Message

[Guest alpazlok]

Hi All,

 

I work on a VG6 with D4/PCI card, the PABX is kind of old Fujitsu module which is out of maintanence.

 

The VG6 able to detect End call from Disconnect tone, it works fine on most of the IVR flow

however, when it comes to voice message recording, it cannot detect the tone completely and left over partitial of the sound at the end of voice message.

 

After trial and error, below setting should able to activate the disconnect detection

D,479,29,618,38,24,2,25,3,1

 

It comes to my notice that the 1st repeatition is NOT the same as other, the volume of the tone grows up, with kind of Fade in effect. U will understand by checking out attached screen capture.

 

I am wondering if the VG cannot match the front-half of the 1st repeatition, and captured on latter-half of the 1st repeatition.

 

It capture the pattern like latter-half of 1st repeatition, which is 0.125s, then silents 0.25s, then front-half of the 2nd repeatition 0.125s.

Then it match on 2nd repeatiion and detect disconnect tone, but leaving the partitial of the 1st tone, and partitial of 2nd tone recorded in the voice message.

 

Any ideas?

Looking at the .PNG screenshots we can see that the first tone is gradually increased in amplitude, so it is possible that Dialogic does not detect the first 250ms part of the tone.

 

As the tone is eventually detected, then it it looks like the resolution to the issue of some of the disconnect tone being included on the recorded message would be to increase the legth of the call that is truncated when the disconnect tone is detected.

 

In v6: VG.INI, in section [PlayRecordConfig] increase the value of the RecCut_EndRecDueTo_ToneDisconnect setting to the value which results in the recording being correctly truncated on your system

 

 

From VG.INI:

 

;When a recording is finished due to a busy or disconnect signal being detected

;the recorded message will be truncated (to remove the busy tone recording from the message.)

;time to be truncated is specified in 100ms units.

RecCut_EndRecDueTo_ToneDisconnect=50
