Hi all,
I am developing a application in c# with TAPI 3.1. My application works for
Call, Answer and transfer. I wrote the function for Hold and disconnect. But
it is throwing error for disconnect and its not responding for hold
i am attaching the code for your view.
This is for call holding
public void TAPICallHold(IEnumCall ec,bool hold)
{
uint arg = 0;
ITCallInfo ici;
ec.Next(1, out ici, ref arg);
ITBasicCallControl bc = (TAPI3Lib.ITBasicCallControl)ici;
bc.Hold(hold);
}
this is for call disconnecting
public void TAPICallDisconnect(IEnumCall ec)
{
uint arg = 0;
ITCallInfo ici;
ec.Next(1, out ici, ref arg);
ITBasicCallControl bc = (TAPI3Lib.ITBasicCallControl)ici;
bc.Disconnect(DISCONNECT_CODE.DC_NORMAL);
ici.ReleaseUserUserInfo();
}
While debugging the disconnect function, found out that it is throwing error
at ici.ReleaseUserUserInfo() function.
The error message i receive is as follows
This implementation doesn't take advises (Exception from HRESULT: 0x80040003
(OLE_E_ADVISENOTSUPPORTED))"
Any ideas please?

Ravi,
Regarding TAPI and .NET see KB article "841712 - Telephony Application
Programming Interface (TAPI) functionality is not supported from managed
code".
See my TAPI and TSPI FAQ:
Q: Are there any .NET wrappers for TAPI2 available ?
http://www.i-b-a-m.de/Andreas_Marschall's_TAPI_and_TSPI_FAQ.htm#_Q:_Are_there_4
You may want to take a look at JulMar's
ITAPI3 - TAPI 3.0 wrapper for .NET 2.0
and
TAPI2 ATAPI.NET - TAPI Application class library for .NET 2.0:

What device / TSP are you using?
Are you sure that it supports hold feature?
Can you reproduce the issue with TAPI Browser TB3x ?
Please post a TB3x log.
See my TAPI and TSPI FAQ:
Q: Where can I download TAPI Browser ?

Q: Is there a user guide available for TAPI Browser TB3x ?

Why do you try to ::ReleaseUserUserInfo() ?
What happens if you just ::Disconnect() ?

You are looking at the wrong error code description.
It is:
TAPI3 error code: 0x80040003 = This method is not supported..
See my TAPI and TSPI FAQ:
Q: Where are TAPI errors codes defined ?
