I have been working on a tapi program that will play a wav file over a tapi phone line. I am look for a GOOD quality voice modem. Any suggestions. The one I am working on is really poor for this project. Things I am looking for.....
[Code]...
I have a modem that CLAIMS to be voice, i still can not get it to do what I want.
1) The modem dials and makes my phone ring, when I pick it up the program does not reconize the event. I have to physically click on button that says Talk. Then my CallStateChanged fires.
2)My other issue is that I can not get any sound to come over the line. I essentially have a wav file that play nicelys on the computer but the modem is not picking it up. Is there some way that I can test the modem to be voice?
I am trying to determine if a modem is busy. I have tried using serial ports which from what i can see just tells me that something is tied to a port or not. It does not tell me if the modem is busy.
My overall question is How do can I determine if a modem is busy? For an added bonus, also is there a way to tell what device is using a particullar port?
I need to develop a simple application. That is, with a click of a button, it will call a telephone number through a voice modem.I'm using MS Visual Basic 2010 Express Edition.I refer to this link : [URL]I tried it, by changing phone number and my COM port. I added System as reference too.Unfortunately, it's not doing any good.
View 7 RepliesI'm developing a VB.NET Windows service which is costantly checking a BMS database for new alarms and making phone calls to warn operators remotely. I'm currently using a .NET TAPI wrapper and the SAPI 5.3 interop assembly, and the steps I'm taking to speak over the phone are:
Initialize TAPI interface;Make the call to the operator's number;Take the voice modem waveOut device id Set the voice output to that device id; Let SAPI do the magic. This is all working fine if I compile the code as a Windows console or forms application, but as soon as I compile and run it as a Windows Service, step 5 never occurs - voice modem calls but stays silent; everything else works, even digit monitoring.Now I know windows services are not supposed to interact with the desktop, so things like UI elements and playing sounds are a no-no, but I'm struggling to find an alternative which doesn't involve using the wave API and can be developed in a reasonable timeframe.
I spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.
I have a voice program that can compare voices to stored voice files and identify people based on that. It's not the most accurate thing, since being sick or other weird things can make it fail, but it does work for the most part. I was wondering if there was a way to keep the voice recognition running during an unlock and wait for the person who locked it to come back. Upon giving the command and voice verification, if it passes, the computer is unlocked by my program. Is there anyway to do this in VB.NET?Summary: Can a program unlock a computer after it's locked?
View 4 RepliesI am attempting to call a remote modem using a local modem connected via USB. Programming language is VB.NET and I am using the SerialPort control to talk to the modem.
Communication is as follows:
I send: ATZ0[CR]
Modem responds: ATZ0[CR][CR][LF]OK[CR][LF]
I then try to dial a number:
I send: ATDTnnnnnnnnnn[CR] where nnnnnnnnnn is a valid number
The modem responds with:ATDTnnnnnnnnnn[CR][CR][LF]ERROR[CR][LF]
All other commands seem to work without any issues
For info the modem is a MultiTech MT5634ZBA-USB-V92
If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control

I am working on an assignment whereby i am requested to receive incoming messages via a gsm modem, i have tried to do so by writing at commands to the serial port where the gsm modem is connected to but there's one specific line which gives me error when i tried writing it to the serial port, (AT+CMGL= "ALL") which returns me an error: CMS ERROR: 305 which means Invalid Text mode parameter The following is the codes i have done up to so far, can anyone tell me what is the correct way to write this specific line to the serial port or is there any other methods that is able to do the same thing?[code]...

(from scratch as I've not done this before) how I can stream live through modem-to-modem connection. The modem here refers to dial-up modem (PSTN modem), there is no internet/lan involved.It will be 2 programs, the first is to transmit real-time video from webcam, and the second is to remote video from the first.
View 5 RepliesI am using system.speech currently. I want to use speech recognition to make a program. However, while the program is running, I noticed that some of the commands for windows (like saying "run") would trigger other program functions. Thus, while the VB.net program is running I do not want this to happen. Also, when the computer starts up, I speech to start listening right away rather than me having to say "start listening". How can I do this? I am pretty sure that it is simple. This is my code so far:

From my program TAPI will call the number. My problem is that its not raising any events. I really need CallStateChange. I raised it from address and moved it up to my TAPI Manager. I put break points everywhere and I can not get anything to raise.
We have a VB.NET application that is using the TAPI3Lib.dll. At this one site we can multiple addresses for the same Phone extension. For example for extension 149 we are getting Extension 149 - Address # where # is 0 thru 208. Is there a way to just get "Extension 149"? Have downloaded some free utilities and they only show "Extension 149".Below is the same of code:
Code
Dim AddressCollection As ITCollection = coTAPI.Addresses()
For Each loAddress As ITAddress In AddressCol

I have problems by paying a wav through the phone line could somebody help me I use getLineID to get the id device for the wav/out but my wav steel plays over the sound card
View 1 RepliesI'm writting what I thought would be a fairly simple TAPI program in VB.Net 2008 SP1 using the TAPI3Lib.dll. It is supposed to dial out a number and once connected play a wav file then wait for digit input. I got through the dialing but it seems I never get the CS_CONNECTED event letting me know the line was picked up. All I get is CS_INPROGRESS then the call is placed and a CS_DISSCONNECTED if I call the call.disconnect method.
I've double checked my registering for events and my event filter and they both check out (otherwise I wouldn't get the two call states I do get). Is there anything else I'm missing or is this normal? I'm calling out with a Conexant HDA D330 MDC V.92 Modem. The call is correctly placed, my phone rings and I answer it. The call state never changes to connected. If I hang up my phone you hear me hang up through the modem and you then hear a dial tone since the modem in the computer hasn't hung up.
I'm looking at writing a application that interfaces with TAPI via the samsung open TSP. The problem I'm having is that after a few days research I am unable to find much info regarding coding for TAPI. There also appears to be alot of contradicting information out there too...
Has anyone got any pointers, examples or sources that I can start looking through??
as I am working on my latest app (tapi interface) I have noticed that things on the form do not always refresh. I am at a loss to explain it. So, in VB.net I have a form with 1 listview, 2 textboxes, 2 labels

I have with a good level of success got a C# application to use TAPI to connect to my office PBX and dial and hangup calls but need to go further and be able to monitor activity and provide CTI to client pc's as well as integration back to my companies web based CRM.
I am focusing on the client app for CTI popups and dial/hangup functions as the phone number lookup to the CRM is relatively easy.
I initially started by registering one handset in the tapi that I could then dial and hangup, I even seem to have registered all the handsets on the system and to be able to dial from any of them but I don't seem to be able to get any activity logs as to when any of the handsets are ringing etc.
Does anyone have any example tapi code that can get me started or point me in the right direction? I can work with C++, C# or VB.Net as I am okay with any of them.
