TAPI 3 problems

[menno...@gmail.com]

Hello Andreas,

Thank you for your quick reply. I was trying to reproduce the error
but
instead of the error I expected I get the following error -> HRESULT:
0x80040052 which means that there is a
resource unavailable. I have had this error before and I just re-
installed my TSP and restarted my pc and phone and the error didn't
occur for some time until now.

Can you tell me a solution for this problem? I read about the TAPI3
wrapper(don't know if that is a solution for my problem) but the link
to the .zip file wasn't working anymore.

For my other problem(the one where I can't connect the call)-> for a
call with a Cisco IP Phone, must I use the mediatype:
TAPIMEDIATYPE_AUDIO? I thought that was the right mediatype. Do you
know what the error(I don't know the hresult error code)
OLE_E_NOCONNECTION (In Dutch: Er is geen verbindings-id voor deze
verbinding) and do you know a solution for this problem as well?

I really hope you can help me and point me in the right direction.

Thanks in advance.

Greetings Menno.

Menno,
is your TSP returning the corresponding TAPI2 / TSPI error
LINEERR_RESOURCEUNAVAIL?

I guess this is the wrong error decription.
You need to know the HRES hex value.

Hello Andreas,

Thanks again for your quick reply,

Regarding to my first question, I got the same message from tsp. In
my VB code I didn't dispose the tapi object and didn't close the line
in the appropriated way. That error is no longer occurring.

The error I now get is as follows: Geen verbinding voor deze
verbindings-ID (Uitzondering van HRESULT: 0x80040004
(OLE_E_NOCONNECTION))
When I looked it up I found out that this is an error from WinError.h.
Do you have any idea how to solve this problem?

I also downloaded a 'TAPI Phone Dialer from Julmar Technology, Inc.'
And it worked perfectly for both incoming en outbound calls.

Here is my VB code:
Dim gobjTapi As TAPI3Lib.TAPI
gobjTapi = New TAPI3Lib.TAPI

Call gobjTapi.Initialize()

Dim gobjAddress As TAPI3Lib.ITAddress
Dim objCollAddresses As TAPI3Lib.ITCollection
objCollAddresses = gobjTapi.Addresses

Dim bFound As Boolean
bFound = False
Dim indexAddr As Long
Dim objCrtAddress As TAPI3Lib.ITAddress
Dim objMediaSupport As TAPI3Lib.ITMediaSupport
Dim objAddressCapabilities As TAPI3Lib.ITAddressCapabilities
Dim nSelectedType As Integer =
TAPI3Lib.TapiConstants.LINEADDRESSTYPE_PHONENUMBER

For indexAddr = 1 To objCollAddresses.Count
objCrtAddress = objCollAddresses.Item(indexAddr)
objMediaSupport = objCrtAddress
objAddressCapabilities = objCrtAddress
If
objMediaSupport.QueryMediaType(TAPI3Lib.TapiConstants.TAPIMEDIATYPE_AUDIO)
And objCrtAddress.AddressName.StartsWith("Cisco") Then
bFound = True
End If
objAddressCapabilities = Nothing
objMediaSupport = Nothing
objCrtAddress = Nothing
If bFound = True Then Exit For
Next indexAddr

If (bFound = True) Then
MsgBox("Valid address")
Else
MsgBox("No valid address")
End If
gobjAddress = Nothing
gobjAddress = objCollAddresses.Item(indexAddr)

Dim gobjCall As TAPI3Lib.ITBasicCallControl
gobjCall = gobjAddress.CreateCall("123",
TAPI3Lib.TapiConstants.LINEADDRESSTYPE_PHONENUMBER,
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_AUDIO)
'gobjCall.Pickup(1)
gobjCall.Connect(False)

When I execute this line of code: gobjCall.Pickup(1) my IP phone
starts to make some noise, like a dial tone, so it is connected.

I really hope you have any idea what may be the problem here.
Hopefully you can help me further.

Thanks in advance (again).

Menno.

P.s. here is a TB log file in which everything seems to be working.

You are (again!) looking at the wrong error code description.
It is:
TAPI3 error code: 0x80040004 = The MEDIATYPE passed in to this method was
invalid.
See my TAPI and TSPI FAQ:

Do you want to make a (new) call, then use ::Connect();
or do you actually want to picku an existing call that is currently ringing at
*another* station, only then use ::Pickup().
Please clarify.

Hello Andreas,

This is really the error that I get: Geen verbinding voor deze

verbindings-ID (Uitzondering van HRESULT: 0x80040004
(OLE_E_NOCONNECTION))

It is a error from WinError.h and not from Tapi3Err.h. The mediatype
that I use is TAPI3Lib.TapiConstants.TAPIMEDIATYPE_AUDIO.
I tried also tried this: MediaTypes =
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_AUDIO Or
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_DATAMODEM Or
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_G3FAX Or
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_MULTITRACK Or
TAPI3Lib.TapiConstants.TAPIMEDIATYPE_VIDEO
but again the same error.
So I guess the mediatype is correct. Do you have any experience with
this error, or do you have a suggestion in which direction I must
look?

I want to make a new call from my VB application. So I tried the
'connect' method. With the 'pickup' method I wanted to let you know
that the connection between the VB application and my IP phone was ok.

Thanks again.

Greeting Menno.

Hello Andreas,

I got an exception on CALL button click event.
System.Runtime.InteropServices.COMException : There is no connection for this connection ID (Exception from HRESULT: 0x80040004 (OLE_E_NOCONNECTION))
at TAPI3Lib.ITBasicCallControl.Connect(Boolean fSync)
at tapi3_dev.Form1.button2_Click(Object sender, EventArgs e)

Please help me.
Thanks in advance
