One Way Voice On D300pci Dialogic Board

[guy_levit]

Problem general description:

 

Dialogic D/300-PCI board can record incoming calls voice but we can not hear what it is plays back

 

General layout of the telephony network:

 

PRI (Primary Rate ISDN) telephony card <--> PRI 2 SS7 protocol converter <--> SS7 switch of the Telephony Company (carrier).

 

 

The current status is:

 

1) We can make a call both ways (meaning, I can make Outgoing calls and Incoming calls to and from the Telephony Card)

 

2) We can make a call from a Mobile phone to the Telephony card and record our voice … meaning the server can “hear” the voice but the voice it plays is not being heard on the other end.

 

3) We where able to loop back the ISDN side of the Protocol Converter, call in and route the call to a different mobile phone.

Voice was just fine.

 

 

We only left with a problem somewhere on the Dialogic board or some sort of missing parameter we don’t have.

 

Notes:

 

1) The board it self was tested before shipment.

2) The application is working as is on identical hardware platforms in many locations around the world with no problem for 3 years.

3) The new server is being installed in China that enforced us to use the protocol converter – we have proven that the converter is not the cause through the tests I mentioned earlier.

4) The Dialogic board is installed on a Compaq DL380 server with Dual PIII 733MHz processor and 512 MB Ram.

5) OS: Microsoft Windows 2000® SP4

6) Dialogic driver set : DNA3.3 with Service Pack 1[1]

[1] Though old, this driver set is installed and working with no problems on more the 8 identical platforms

Which version of VoiceGuide are you using?

 

DNA3.3 does not have good support for Wave drivers which VoiceGuide uses to play and record sound files.

 

This support was well implemented starting with SR5.0 onwards.

 

I'd recommend installing SR5.1.1 and trying again.

 

Could you please send us a copy of VoiceGuide's Debug Printout which captures the playing of the sound files, this will allow us to see what is going wrong.

(When running the script click on VoiceGuide's View menu and select 'Event Trace Log' option - any log information will then appear in this window. You must open the trace window before making the call.)
