JTAPI vs TAPI

[Saberium]

Q :
Is there differences between TAPI from microsoft and JTAPI for Java ?
Is it a complete and good port of all the TAPI functions ?

D :
I mean I'm used to develop in Java for its great portability and
especially its cost but since I'm all new to TAPI and I'm learning on
the way, I fear if I opt for JTAPI (and thus develop my soft in JAVA) I
will discover late in the future that some TAPI functions and services
are not well ported to JAVA. (This information is crucial for the
choice of the development tool)

PS : Sorry for my english if there is any mistakes.

Thanks in advance.

Saberium,

despite the similar names JTAPI is completely different from TAPI.

Most PBX systems come with a service provider for TAPI but
only very few for JTAPI. You can't use JTAPI to control TAPI
devices.

Portability is useless in this case because TAPI only exists on
Windows and there is no comparable thing (especially with
regards to industry support) on other platforms.

Another thing to mention is CSTA which is supported by a number
of PBX systems, but it is rather a communication protocol than a
programming API.

There are some Java samples for TAPI but I wouldn't recommend
going that route. Either use TAPI 2.x with C++ or TAPI 3.x with
C++ or VB6.

If you're considering .NET please note:

Regarding TAPI and .NET see KB article "841712 - Telephony Application
Programming Interface (TAPI) functionality is not supported from managed
code".
http://support.microsoft.com/kb/841712

Please have a look at JulMar's
ITAPI3 - TAPI 3.0 wrapper for .NET 2.0
existing TAPI3.0 code based on TAPI3 interop can easily be ported

Thanks a lot Matthias, Really, you helped me a lot with your well
developed and accurate answer.

After reading the TAPI and .NET references I will opt for C++ as the
programming language.

HI Matthias,

I would like to clear some doubts?

I have a CRM Product, and I would like to implement CTI. First I checked the
possibility of Envox CT Connect. Now I am considering TAPI/JTAPI. can you
guide me on the following doubts

1. I saw an architectural diagram saying JTAPI is written over TAPI
functionality? Is that mean even if I am coding with JTAPI, I will get
support for all the vendors?

2. There are many vendors , say Avaya,Cisco,Nortel,mutel...etc saying that
they have TAPI Support and they are providing a kind of TAPI SDK(Software
development kit). Does this mean I need to implement CTI(Computer Telephony
Integration) vendor by vendor?

3. Can I write a general code using TAPI, and leave my application to our
customers , So that they can just configure (TSPI) with respect to their
choose?

4. How will I implement a multi vendor supported client application, from
where my helpdesk technician can answer,click to call, ANI..etc

Thanks in Advance

Regards
Shihab

I am quite sure that this is wrong.

Not generally, TAPI is a common API. There are vendor specific extensions
for certain functionality, though, that's why they are providing SDKs.

Yes if your code is perfect. But when you write and test your code against
a certain TSP it is likely that the code might not work perfectly with other
TSPs, so you should at best test with all TSPs and if that's not possible,
at
least add good logging code to be able to easily identify problems your
customers
might experience with other TSPs.

Thanks a lot..

I have few more doubts.

My design would be a screen pop up while a call is coming, make call, answer
call..etc. I was able to configure the server and client machines in a same
domain. Now its time to do some POC. a Third party call control design would
be better as we need to support PBX

I went through your blog, which is awesome and useful. Also I went through
your recommendations.
1. Can you provide me a guide how to do a POC for the above features?

2. How the data flow is working client, server, and pbx? Can we have some
tools to see the call flow?

3. Do I need to install a TSP in all client ? If not when I am making a
call will that go through the Telephony server?

4. To push a screen pop to the client how can i get a Notification from the
PBX, or How can I make Telephony server listening to the PBX?

5. How the Telephony server maps the client IP and extension? (Please not
PBX will map extension number and user)

If you have some links where step by step configuration for POC is avaialble
.. Please help..

Sorry for the disturbance

Regards
Shihab

Shihab,
what do you refer as "POC"?

> 1. Can you provide me a guide how to do a POC for the above features?

There is a collection of very usefull TAPI tools (including open source in
C++) from JulMar:
http://www.julmar.com/tapi/
Please take a look at Answer.exe, TcMon.exe, and Phone.exe.

See my TAPI and TSPI FAQ:

With MS TAPI client/server architecture you only install the 3rd party TSP for
the PBX on the telephony server.
On all telephony clients you just need to "TCMSETUP.exe /C
<telephonyservername>" what locally installs the MS RemoteSP.TSP, that is
doing the communication with the telephony server (and the TSPs there).
On the telephony clients you have access (via RemoteSP.TSP) to the TAPI
devices on the telephony server that are assign to the currently logged-on
user.

> 4. To push a screen pop to the client how can i get a Notification from the

This is done by the 3rd party TSP (for the PBX) running on the telephony
server.

> 5. How the Telephony server maps the client IP and extension? (Please not

See 2+3.
The assignment of TAPI devices to users is done via TAPIMGMT.msc on the
telephony server.

Hi,

Thanks for the help. a POC is nothing but, Proof of concept. A skeleton
running from command prompt, which we can develop later.

I would like to know a bit more about #4 and #5.

#4& #5. Hope the telephony server will notify the client while a call comes,
If thats the case its easy to pop up in the client machine

But a scenario where a company ABC running say Nortel PBX and hardphone. Now
our solution is going to implement. The nortel pbx will have the information
about the user say John/peter whose numbers are 6500 and 6600. As we are
going to implement TAPI, Nortel TSP will notify TAPi server when a call comes
to John(say there is a call coming to 6500) . Now how the TAPI server will
notify the John's laptop (pop up message saying "peter is calling you") .
please keep in mind johns laptop is a client of TAPI server. but the TAPi
server doesn't have a number to laptop mapping. Can you please clear, how the
TAPI server will map these things

Thanks &Regards

Shihab

Yes on the telephony client you will automatically get the incoming call
notifications via TAPI for the device(s) assigned to the currently logged on
user from the TSP running on the telephony server.

The telephony server is required to have a mapping of domain users (e.g. John)
to TAPI line devices (e.g. device 6500 from the Nortel TSP).
This mapping is configered via TAPIMGMT.msc on the telephony server.

Please see the PowerPoint presentation and the MS KB article I already
referenced.

Hi,

It was a wonderful answer. Thanks a lot.

Now to develop, I was thinking a development set up like this. We will use
Asterisk PBX, as PBX, AStTAPI driver can be used as TSPI, and some SIP
phone(SJPhone) for calling. The above set up can be used to simulate the
call traffic. We will run POC using a dialer from one of the client to
another client to make a call

I was able to make client/server configuration , But unfortunately while
dialing using dialer I am getting the following exception is Asterisk logs

I went through your tool error codes and find the explanation as "TAPI2
error code: 0x80000048 (dwMessageID = 0x0000e048) = The operation failed for
unspecified reasons".

I checked the username/password in manager.conf, and verified the driver
user/pwd is same.

Can you shed some light on this?

or Can you tell me some other development simulation environment or a third
party call control simulation so that I can start development?

Please look to the following error log. It may give a fair idea why TAPI
login to PBX is failing. (I double checked user/pwd in both place)

Thanks in Advance

Regards
Shihab

Sorry, I'm not familiar with PBX / TSp /phone you've mentioned.

Unfortunately this error code is the most generic one and doesn't tell you
much about the underlaying issue.

See below.

Maybe H323.TSP (from MS, being part of W2k, XP, WS2k3, but not Vista / WS2k8).

See my TAPI and TSPI FAQ:

Q: What about H323.TSP and IPconf.TSP in Windows® VistaTM ?
http://www.i-b-a-m.de/Andreas_Marschall's_TAPI_and_TSPI_FAQ.htm#_Q:_What_about

Or maybe ESP32 from MS.

See my TAPI and TSPI FAQ:

Q: Is there a user guide available for Economical Service Provider (ESP32)?
http://www.i-b-a-m.de/Andreas_Marschall's_TAPI_and_TSPI_FAQ.htm#_Q:_Is_there_8

Or maybe DSSP or JPBX (being part of TSP++ package) from JulMar:

From your log it seems that errror occured at lineGetID()
but unfortunately the log doesn't indicate what DeviceClass was queried.
