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 modems..... what else could be the possibilities Thanks in advance , waiting for ur kink help irfan

- 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?

In that my application have to be notified of whether the reciever lift the handset or not.I tried with analog modem.Andreas Marschall has advised me to use Dialogic board.what are the changes i have to do in my application in order to detect whether the reciever lifts the handset. Please advice me. I am very badly in need of it Thanks in advance Regards Srini - 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?
