Re: TSP Bug? LINE_CALLINFO messages come in AFTER the call is idle?

2009-11-21T11:17:50Z

Fred,
are you saying that you receive a LINE_CALLINFO message for a hCall that you
previously deallocated (i.e. lineDeallocateCall() already returned)?
If so, are deallocation and message reception taking place nearly at the
same time?
Maybe this is some race condition caused by multi-threading (maybe even only

Re: Who maintains Call States?

2009-11-21T08:12:43Z

Mohit,
solely the TSP maintains the call states.
The TSP sends LINE_CALLSTAE messages to TAPISRV,
TAPISRV passes these messages to TAPI apps monitoring this call.

Who maintains Call States?

2009-11-21T05:46:01Z

Hi Friends,
Can any one tell me that in TAPI, who maintains the state of the call?
I mean, when an incoming or outgoing call is made using TAPI Application
then the call is passed from various call states like, Offering, Connected,
Idle, Diconnected, etc. So, who maintains these call states, TAPI

TSP Bug? LINE_CALLINFO messages come in AFTER the call is idle?

2009-11-20T22:26:34Z

It seems a PBX manufacturer isn't followomg the TAPI spec for sending
messages about a call after it has entered the idle state. We
deallocate the call as soon as it goes idle and have seen now that a
new version of the TSP for a major PBX manufacturer changed its
behavior and "broke" our code.
This PBX is sending the LINE_CALLSTATE message of IDLE, and then later

Re: Contradictory info in MSDN for lineOpen (dwAddressMode, dwPrivileges)

2009-11-20T22:10:20Z

Hi Andreas,
How about the MSDN help? Did you see where I see the help for
lineOpen says to limit messages to a single address you must set
dwAddresMode = LINEADDRESSMODE_ADDRESSID, yet in the LINECALLPARAMS
help is specifically says you can't do that? I think the call params
section must be wrong, but wondering how it got like that. I updated

can not use atsp32 with dialer.exe

2009-11-20T15:00:14Z

Hi!
I am playing around with atsp32 sample. Building, installing and
configuration works fine. When I start dialer.exe, I can see the lines
offered by atsp32. But when I choose a line and press OK, dialer.exe
does not accept it, because next time when I enter the configuration the
line for phone calls is switched back to <automatic selection>.

Re: TSP maximum users

2009-11-20T13:46:49Z

Scrumpy,
does every client user use a different TAPI line device?
Is each TAPI line device only used by one client user?
I.e. how is the mapping in TAPIMGMT.msc?
Test to exclude client/server issues:
please disable Telephony Server checkbox in TAPIMGMT.msc
and try to MakeCall from multiple instances of Phone.exe with the same line

with users i mean multible PCs using MS TAPI client/server
architecture (i.e. TCMsetup.exe )
and i used JulMar's Phone.exe to reproduce the steps of our program
we also used JulMar's tcmon.exe for monitoring and it seems that there
are still calls that have the status "unknown"

Re: TSP maximum users

2009-11-20T11:11:11Z

Scrumpy,
what do you refer as "users"?
- Multiple instances of your TAPI app on the same PC?
- Multiple TAPI line devices user by your TAPI app on the same PC?
- Multiple PCs using MS TAPI client/server architecture (i.e. TCMsetup.exe
and RemoteSP.TSP)?
- Anything else?
Please clarify.
Anyway, to exclude your code from the scenario you may want to use JulMar's

We are developing an callcenter application.

The problem that we are having is that if there are 8 users using the

Re: Calling number information in LINE_NEWCALL

2009-11-18T12:15:01Z

Mohit,
a TSP doesn't send the calling number on its own to TAPISRV
but only on request from TAPISRV via TSPI_lineGetCallInfo().
The TSP fills in the CallerID members of the LINECALLINFO struct.

Calling number information in LINE_NEWCALL

2009-11-18T11:44:01Z

Hi friends,
Can any one tell me that how a TSP sends Calling party number receved from
the CO with the incoming call to the TAPI.
I had checked MSDN library and according to that, when an incoming call is
received on any opened line by TAPI then it is reported by TSP using
LINE_NEWCALL message to the LINE_EVENT callback function. But according to

Mohit, you are welcome.
TUISPI_providerInstall() / TUISPI_providerRemove() are called:
a) on lineAddProvider() / lineRemoveProvider()
b) ControlPanel / Phone and Modem Options / Advanced tab / Add.../Romove
buttons
So basically you need these functions to be able to install and de-install a
TSP.
The implemantation is mandatory.
