Thanks

Hi,

which hardware do you use? A modem?

Please make sure that the Unimodem Half-(/Full)Duplex Wave Driver
is installed correctly and you see "Modem #x Line Playback" (/Record)
listed under Control Panel >> Sounds and  Audio Devices >> Audio.
(Don't set them as default, just make sure they are in the dropdown list.)

Best regards,

Yes we are using a modem.
Here is the weird senario.
The file that I cant play will work if i lower the bit rate to 128kbps and audio sample to 8 kHz.

Is there a way we can setup the teraserver to play wav files with bitrate over 128?
Can teraserver handle mp3 files instead?

Hi Simon,

basically TERAVoice should be able to play any file that
Windows Media Player can play (i.e. if the required codec
is installed). At the moment I'm not sure why the one file
does not play.
TERAVoice can also play mp3 files but we have encountered
crashes with the mp3 codec installed with Windows when
multiple lines are used (= more than one simultaneous playback).

For a professional system we recommend using the native audio
format which does not involve any conversion and results in best
performance and audio quality:

Windows PCM (.wav) 8kHz - 16 Bit - mono

Thanks.
After i converted the wave file using lame to an 8 kHz it works.

I have another one. Sorry for all of these but I have very limited knowledge with IVR scripting.

What i want is that the when a caller calls, the system will pickup the CALLER ID then play
the wave file we have in file. If the number is not available or its not in file it will play
the wave file notfound.wav.

Here is what i have so far. The problem is that when I call, it will display the default message ( teravoice anouncement ) then hangs up. Also the same with unknown numbers. Can you check the script that i have and maybe fix it for me?

---
Sub CallHandler_TimePulse()

        CUSTOM_name ="\" & CallerID & ".wav"
        If Not CallController.IsPlaying Then
            If Not CallController.PlayAudioFileList(BasePath & CUSTOM_name) Then
                CallController.PlayAudioFileList(BasePath & "\notmember.wav")
                CallController.HangUp
            End If
        End If

End Sub
---

If i just do this, it works fine but it will not play the notmember.wav if the callerid wav is not present.

Sub CallHandler_TimePulse()


If IsPlayed Then Exit Sub
      
PlayAudioFile BasePath & CUSTOM_name

IsPlayed = True

End Sub



Thanks again for the help.

Simon,

the PlayAudioFileList method requires an array of audio files, eg.:

Dim arrFiles

Redim arrFiles(2) ' Creates an array of 3 files

arrFiles(0) = BasePath & "\1a.wav"
arrFiles(1) = BasePath & "\2a.wav"
arrFiles(2) = BasePath & "\3a.wav"


You may not call hangup directly after calling a playback method.
Either wait until IsPlaying = False and hangup just then or hangup
in the CallHandler_PlayDone() event.

All playback methods are async, so the functions return immediately
not when playback is done.

Got it.

Its working now using this script:
--
If IsPlayed Then Exit Sub
            If Not CallController.PlayAudioFile(BasePath & CUSTOM_name) Then
            
                PlayAudioFile(BasePath & "\notmember.wav")

            End If
IsPlayed = True
-

My only problem is that notmember.wav is not played till its over. Its cut in the first sentence then hangs up. I listen to the wav file and it plays all the way to the end. Is there a way I can fix this?

Thanks again for the help

Simon,

you must set

IsPlayed = True

in the CallController_PlayDone event, not during the TimePulse event,
then it should work fine!

Hi Frank,

Still cutting the voice message of notmember.wav after a few seconds.

here my script. Can you check which part I am missing? Any recomendations?

--
Option Explicit

Const BasePath = "C:\voice_post\"

Dim IsPlayed
Dim CUSTOM_name
Dim CUSTOM_missing


Sub CallHandler_CallLogEntryEvent(EntryID, CallDate, CallerID, CallHandlerID, CallHandlerName, CallHandlerType, CallDetails, CallDetailsAddition, MessageLength, MessageFileName)

End Sub

Sub CallHandler_CallTransferResult(Succeded)

End Sub

Sub CallHandler_DigitReceived(Digit)

End Sub

Sub CallHandler_FileSaved(FileName, Length)

End Sub

Sub CallHandler_Init(objCallController)

End Sub

Sub CallHandler_OutgoingCallFailed()

End Sub

Sub CallHandler_PlayDone()
IsPlayed = True

CallController.HangUp

End Sub

Sub CallHandler_ScheduledInit(objCallController, InstanceCount)

End Sub

Sub CallHandler_TimePulse()

CUSTOM_name ="\" & CallerID & ".wav"


If IsPlayed Then Exit Sub
      
        If Not CallController.PlayAudioFile(BasePath & CUSTOM_name) Then
                CUSTOM_missing = 1
        End If
        If CUSTOM_missing Then
            PlayAudioFile(BasePath & "\notmember.wav")
        End If


IsPlayed = True

End Sub

Sub CallHandler_UnInit()

End Sub

Thanks again.

Hi Simon,

the problem is this: When you try to play a non-existant audio-file,
TERAVoice
treats this as an error and disconnects. Thus you cannot use the
PlayAudioFile
function to check for existance.
To work around this just use the FileSystemObject to check if the file
exists.
Please find your modified script below.

Hi Frank,

still did not work but thats ok. We will deal with this once we buy the 'not free version'.

also, in the paid version, we can remove the commercial recording right? ( 'hello you are connected to a tera voice telephony server' )


Thanks again for all your help

I tried the exact script without problems. To further work on this issue we
can
switch to e-mail (support...terasens.com). Please provide an exact copy of
the script
you are using and a debug log file of TERAVoice reproducing the error.

> also, in the paid version, we can remove the commercial recording right?
> ( 'hello you are connected to a tera voice telephony server' )

Yes, there is just no such message in the retail version.
