  • 1. Help! Iterating throughcall offered on address
    Hi All, Any help or advice on this would be very much appreciated. I have spent quite some time researching this and have found no solution as yet. This is being implemeneted on the CCM. I need to detect calls being offered on an address that arrived prior to calling lineopen. Using linegetnewcalls is not an option, since the TSP implementation on the client machine will already have been started by another application. And as far as I am aware is not intended for such purposes. lingetaddressstatus, linegetdevstatus although appearing promising does not display the calls offered on the address. I do have the dwCallId as retrieved earlier in the calls lifetime from the LINECALLINFO structure. Is it possible to use this Id in some way to retreive the call status? Any suggestions?

  • 4. lineAnswer disconnects phone line
    Hello, When using Unimodem, calling lineAnswer causes TAPI response LINECALLSTATE_DISCONNECTED. What can cause that? rtn = lineAnswer(hNewCall(lineNo), "", 0&) Return from lineAnswer is a positive number. hNewCall(lineNo) is valid handle to the active call However before lineReply, there appears LINECALLSTATE_DISCONNECTED message and then after it lineReply returns LINEERR_OPERATIONFAILED. Under what circumstances lineAnswer can cause LINECALLSTATE_DISCONNECTED message?

Full duplex voice communication

Postby irfan » Thu, 29 Jun 2006 12:45:50 GMT

Hello every one...
i am writing an application for voice calls between two modems, (full
duplex speaker phone modems conexant RS56 sp PCI ) .
Now the problem is that i open wave in of my modem and then if i try to
open waveout of modem it gives me an error...  i was thinking that
whether my modem is not full duplex. But i came to know that it is full
duplex but the drivers installed for this modem are Unimodem Half
duplex audio drivers ,,, is this the reason that i m not being able to
open both wave in adn waveout devices of my modem or there might be
some other reason. i am using TAPI 1.4 for my application....
One more thing to ask that can i make a full duplex call using such
technique i.e by opening wave in and wave out devices of my full duplex
what else could be the possibilities
Thanks in advance , waiting for ur kink help
