Caller Id Detection Problem

[arba7ak]

Dear Sir,

 

I'm using VoiceGuide 7 with Dialogic Card.

 

It was working fine with Analog Land Lines. I have now added new GSM Line through a HUWEI B970. I had a problem with the new GSM Line. When any new call comes on that line I see a message comes in the Monitor with (Global End-Of-Call DTMF) after the first ring then start to detect the second ring as ring1 then receive the call normally but through VoiceGuide it detects the Caller ID with an appended "c" letter to it. i.e. if the caller number is "22233343" it is recorded as "22233343c". This problem doesn't happen with other Land Lines and I have the caller ID received OK and there is no (Global End-Of-Call DTMF) signal after first ring.

 

I think that VoiceGuide is detecting some DTMF signal wrongly during caller ID detection which causing this behavior.

 

Could you guide me please how to solve this issue.

From your description it sounds like the HUWEI B970 is set to relay the CallerID information using DTMF tones, yes?

 

Is the extra 'c' appended at end of the CallerID number, or is it sent instead of the last CallerID digit?

 

Are you currently using the Global End-Of-Call DTMF setting as a special DTMF tone is used on this or other lines to signal end of call? What is the tone used for the Global End-Of-Call DTMF setting?

 

Can you please post a VoiceGuide trace capturing system startup and a problem call arriving over the HUWEI B970. (Please .ZIP up any traces before posting)

Hello,

 

Thank you for your help.

 

Actually I'm not sure about how the HUWEI Device relays the Caller ID but when I connect a normal Panasonic Handset to the HUWEI Adapter it detects the caller ID normally.

 

The 'c' letter is appended to the number not replacing the last digit.

 

for Global End-Of-Call DTMF setting how to check or change it? I was having a problem on End of call detection along with the problem stated here and I followed the guide to record it with VoiceGuide and get the parameters using Audicity Software and now it is detecting the End Of Call correctly once the call ended but the End-Of-Call DTMF problem still exist. But I couldn't find the configuration file where End-Of-Call DTMF is defined or set. Kindly help me to find it.

 

For the VoiceGuide trace capture could you tell me where to find this file?

 

Thank you for support.

The trace logs can be found in VoiceGuide's \log\ subdirectory.

 

Please .ZIP up and post the vgEngine and ktTel traces that capture the system startup and the incoming calls.

Thank you kindly find the attached folder files as requested.

Traces show that Dialogic card is receiveing a DTMF 'c' as part of the DTMF string sent to it by the GSM media gateway.

 

Looks like you will need to strip out this terminating letter to obtain an all numeic CallerID expression.

 

An Evaluaten Expresson type module can be used to do this. Have it evaluate this expression:

 

Replace("$RV_CIDNUMBER","c","")

 

And use the $RV created by the EvaluateExpresson module throughout rest of script.

 

 

 

eg. if your Evaluate Expression module is titled CidToNumbersOnly then the expresson in your module [GetCallerDetails] in your sceipt would need to change to:

 

EXEC sp_IVRCallingCustomerGet @CallerID = $RV[GetCallerDetails]

Thank you for you help.

 

What about the Global End-Of-Call DTMF which is received by first ring and call dropped then start receive the call again from second ring. Where I can find the definition of the Global End-Of-Call DTMF in VoiceGuide Configuration to change it and prevent this from happening.
