Inband Signalling Configuration File

08/04/2004 06:55 PM

I need help with the Inband signalling configuration file for a Samsung DCS phone system. I am interested in the phone extension. An * is sent along with a 3-digit phone extension.

08/05/2004 08:48 AM

To capture what tones are being sent on the line just set up a VoiceGuide script whose first module is a "Get Numbers" type module - that module will then capture the sent digits and what it captures will be stored in the Log File.

Please post a trace of an incoming call - we will the be able to see exactly what is being sent by your PBX and will then be able to provide you with an Inband Signaling configuration file.

We are now able to retrieve the phone extension,

Is there anyway to distingusih between calls that have been BLOCKED by turning off callerid or using *67 - 'PRIVATE' or' ANNONYMOUS'. And calls in which the callerid is not recognized - 'UNAVAILABLE' or 'OUT OF AREA'

08/05/2004 09:06 PM

Does the Samsung send different Inband Signaling info depending on whether calls are 'PRIVATE'/'ANNONYMOUS' or 'UNAVAILABLE' or 'OUT OF AREA' ?

Do you know how the Dialogic D/4pci cards recognize callerid. Does it differentiate between an Unavailable, Out-of-area or blocked.

08/11/2004 09:11 PM

Yes it can.

I am trying to determine if a caller blocks his caller id. In our old system a blocked call was received as string of 7's.

We attached a tape recorder to the line and we could hear that information is being sent when caller id is blocked.

The log file has the following information:

I assume that you are using a PBX?

If yes, then which one?

Is the PBX set up to send Inband Signaling?

Are you using a Dialogic card or Voice modem?

08/18/2004 01:41 PM

We have 12 lines. 4 are connected to the PBX. The 8 lines we are talking about are connected to the Telco. CallerId is working with these lines, but we don't get "out of area" or "private calls".

Is there a parameter to receive "out of area" or "private calls" information from the telco lines?

08/18/2004 10:27 PM

CallerId is working with these lines, but we don't get "out of area" or "private calls".

The telco should send this info in the same way it sends normal CallerID info. You should speak to the telco as to why it isn't doing this.

Can you use any external CallerID detection devices attached to these lines to detect the "out of area" or "private calls"?

Questions concerning telco Private Call & Out of Area

External Callerid devices do display the caller id including calls that are Private Call and Out Of Area.

If we listen to the sound (modem tones) between the first and second ring it is the same sound for a Private Call or valid callerid.

Is there someway to capture the digits from the telco so we can see what they are sending? Is there a parameter list or conversion table related to callerids that are Private Call or Out of Area codes?

Questions concerning inband signaling for our pbx calls

Inband signaling is working fine except when the caller presses touch tones before we prompt for them. These touch tones are picked up by the inband signaling process making the extension number invalid.

The touch tones from the callers phone are picked up by inband signaling before the ringing stops and after the ringing stops. "rings before answering call" is set to 2.

Is there a way to discard the touch tones from the callers phone before we prompt them to enter their response?

If we listen to the sound (modem tones) between the first and second ring

How can you listen to them if the phone is still ringing? Does your phone company still send the CallerID info if phone is picked up after 1st ring? (if yes then can please you record them using the Record module)

it is the same sound for a Private Call or valid callerid

All modem communications sound fairly similar - just white noise... do you hear just noise on the line or is it a series of distinguishable tones?

Inband signaling is working fine except when the caller presses touch tones before we prompt for them.

And are the tones then appended to the end of the Inband Signaling info or are they inserted within the Inband Signaling sequence?

The touch tones from the callers phone are picked up by inband signaling before the ringing stops.

This is a bit strange - DTMF tones should not be detected if they are pressed before the call is answered - could you please post a copy of VoiceGuide's Debug Printout which captures the problem, 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.)
