code to identify the number

Question

Hi All,

I got one problem while doing one TAPI application based project in C#. I'm using ITAPI3.dll

My problem is.. i'm not getting incoming call information. To get the incoming call information, i'm using the get_callinfo function, but it is showing empty message.

Answer 1

Did you try a different modem? TAPI is very hardware dependent

This might be a useful MSDN starting point:

Answer 2

I'm just experiencing the same problem. When i debug, a openfiledialog opens asking me to open a file. i'm no sure what it is right now, will get back when i find something. So i just skips the line of code, what causes it to be empty.

I found what was causing the problem for me :

get_callInfo has 3 constructors : one returning object, one returning int and one returning string. For some reason, the one returning object is failing. So i tried the string constructor. This gave me all the information i need. I'll give an overview of all attributes you can choose from :

e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDIDNUMBER); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDIDNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDPARTYFRIENDLYNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLERIDNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLERIDNUMBER); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLINGPARTYID); e.Call.get_CallInfo(CALLINFO_STRING.CIS_COMMENT); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CONNECTEDIDNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_CONNECTEDIDNUMBER); e.Call.get_CallInfo(CALLINFO_STRING.CIS_DISPLAYABLEADDRESS); e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTINGIDNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTINGIDNUMBER); e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTIONIDNAME); e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTIONIDNUMBER);

hope this still helps
