Is this Siemens Phone TAPI compatible ?
chanta...@clubobs.com
I would like to know if the Siemens Gigaset S150 is TAPI compatible ?
It's not very clear on their web site and some others resellers tell
that this model is TAPI compatible.
If this model is not TAPI compatible can you tell which Siemens models
are TAPI compatible.
Thanks in Advance,
Chantal

Chantal,
a Google search on "Siemens Gigaset S150 TAPI" showed these results:
http://www.google.de/search?hl=de&q=Siemens+Gigaset+S150+TAPI+&meta=
One is a link to a Siemens Technical Product Comparator:
http://communications.siemens.com/cds/cp/product/tech_compare/0,2643,hq_en_0_15700_rArNrNrNrN_pageType%253Adisplay,00.html
that states:
PC features Gigaset S150
CAPI 2.0 and TAPI 2.1
So it seems to have TAPI support...
Btw. I have a Siemens Gigaset SX353isdn that definitely has TAPI support.
Its TSP (TAPI Service Provider) is called "Cordless Phone Service Provider"
(file name HomerTSP.TSP).
Unfortunately it has very limited feature support:
- you can basically only make outgoing calls
- no support for incoming calls (no notification at all)
AFAIK all Gigaset with TAPI support use the same TSP.

Matthias,
with my Google query it was the 2nd result ;-)
chanta...@clubobs.com
Thanks for your answers but I know how to use google !
I'm sure you're very nice guys in real life. (And I like nice guys...
;o))
But...
I found (of course) the link you mentioned but when I'm going to the
Siemens web site, and, I looked at the technical data web page nothing
is written.
It's in french but when I'm going on the UK page nothing is mentioned
too.
On their web page, the SX353i is confirmed to be TAPI compatible.
Outgoing calls is enough, btw.
So I would like tohave an "real" confirmation. I hope you understand.
Cordialement (with kind regards)
Chantal
Matthias Moetje
don't you think it's remarkable that you received
the identical answer from two different people indenpendently?
We know a bit about TAPI but we don't know
about each products and if it supports TAPI or not.
So, the other answer I could give is surely something
that might have come to your mind, too ;-)
Why not ask Siemens or a retailer where you might
want to buy it? Or if you already own it, contact
Siemens customer support...

Matthias Moetje

Matthias,
I guess the difference is my additional "Siemens" keyword.
Without it I get the mentioned link as #1 too.

if you had posted this info (about the links you already visitied) on your
initial posting then you could have saved us some time!
chanta...@clubobs.com
I'm sure you know a lot about TAPI but that's not the point.
And it's because i didn't find a definitive answer to my questions with
google that I posted here.
To be complete, I wrote to Siemens on monday 1st august but I'm still
waiting for an answer.
I'm sure you can understand that if i'm asking you the question, it's
because I try to have an definitive answer. I don't want to spend 109
euros for a non Tapi phone.
You will certainly not believe me but spend at least 5 hours to find
the Siemens models doing TAPI and I failed excepted the SX353 isdn
model.
And, this is not so simple, because the Siemens seems to have a very
versatile documentations.
I apologize to everyone if my words were a little bit acid...

I respect people in general life and I do my best to not disturb them
with my questions before I try on my own...
As I wrote to Matthias, I spend really too much time on this question
without obtaining a definitive answer so I decided to post here.
I'm sure you can understand that I feel a little sad to just have "a
google answer" even if I appreciate that people took on their time to
answer me.
So my question remains without a definitive answer.
May be you know some others companies doing TAPI phones and available
for the general public.
I really want to make asap my own tapi application with my beloved
delphi.

Here is my answer:
I have been developing TAPI based solutions for Ericsson, NEC and
now
Siemens.
From my past 2 months of experiance, Siemens HiPath 3000 and 5000
supports
TAPI. As for the phones, any phones whcih are connected to these 2
pabxs
will work for tapi commands.
I am developing a CSTA based driver for Siemens 4000, currently.
And for the 3000 and 5000, or any other Siemens products,
you need to download the TAPI170 version 2.0 driver from Siemens
website.
If you can't get the TAPI driver, email me at g...@avti.com.my to
obtain the
driver.

Chantal,
My last reply was in no way intended to keep you from posting your questions
here.
It was "only" about how to write a good question.
It is simply recommended to supply as much information as you have in your
question, so that other who want to help don't need to do double work.

You can start developing TAPI apps with other TSPs, e.g. UniModem.TSP is a TSP
for modems.
Or you can your ESP32.

G.,
what do you mean by "or any other Siemens products" regarding HT170 ?
This TSP is only for HiPath 3000 bases PBXs (and it precessor Hicom 150E
Office).
It _cannot_ be used on Siemens Gigaset phones (unless they are attached to
this PBX).
Btw. I should know because I developed HiPath TAPI 170 TSP...

also have a look at this list:

Matthias,
thanks for the link.
This list is definitely not complete, e.g. the HomerTSP.TSP for Siemens
Gigaset SX353isdn et al. is missing completely.
Out of curiosity I checked the PBX list:
http://www.estos.com/support/driver/tapimanus.htm?inall=1&intype=1
Or especially for Siemens telephony equipment:
http://www.estos.com/support/driver/tapimanus.htm?inmanufacturer=Siemens
These lists seem to be - let's say - biased towards Estos' own products: e.g.
HiPath TAPI 170 is missing from the list for most Siemens PBXs or they are
only mentioning an old version. Additionally the mentioned features of HT170
are listed incompletely, I guess intentionally...

You are probably right. On the other hand the main reason to prefer
the Estos TSP over of the Siemens TSP is trivial: pricing

Well, this is probably worth much more than the additional cost.
On the other hand I still find it strange that it is cheaper to buy
the Optiset Control/Data adapter hardware instead of the 3rd
party TSP (if you have less than 10 phones..)

Thanks Matthias!
Just for clarification: my support on this is voluntarily (like on any other
topic in this newsgroup) and not part of the purchased Siemens product.

What is strange about this?
You pay less and you get less, i.e. "only" the 1st party CallBridge TSP (as
oppsoed to the 3rd party HT170 TSP).

Of course those extra features might be useful for some, but I think
the most common use is assisted telephony for which purpose the
features of the data adapter are sufficient. Though, it would be preferable
to have a software-only solution instead of installing data adapters and
serial cables on all seats. Due to the pricing in this case people are
"forced"
to go the hardware route instead of 3rd party TAPI.
This is where Estos comes in and offers an attractive alternative Siemens
does
not supply. (btw I have never tried the Estos solution and don't know how
well it works or not - my considerations are only regarding pricing
strategies.
And guess what? We are using Optiset data adapters....)

Matthias,
did you ever take a look at the HT120 - the "little brother" of HT170?
For a limited number of clients it's free of charge!
Hipath TAPI 120 can only drive one device per PC and doesn't have the 3rd
party features (ACD procy etc.) available.
HT120 is using a CSTA link like HT170, so no additional hardware (compared to
HT170) is required.
Product description from Siemens download site:
http://www.siemens.com/index.jsp?sdc_p=pHPo1182111u0l1&sdc_flags=19
HiPath TAPI 120 V2.0
TAPI Service Provider (1st Party): HiPath TAPI 120 for HiPath 500
and HG1500.
Software version 2.0, build 2.0.47.0000
1st party TAPI service provider for PC-supported telephony on
HiPath 500 or HiPath 3000 telecommunications systems. In HiPath 3000, HiPath
HG 1500 must be integrated.
HiPath TAPI 120 V2.0 is a full version subject to licensing. For a
limited number of clients the software can be operated without licenses. The
number of clients that can be operated without a license depends on the HiPath
communications system being used.
HiPath TAPI 120 V2.0 permits PC-supported telephony using CTI
software from different vendors. Installing HiPath TAPI 120 V2.0 on the PC
enables the use of TAPI-compliant CTI software.
Supported communications systems:
HiPath 500, HiPath 3000 with integrated HiPath HG 1500
Supported operating systems:
Windows 98, Windows NT 4.0, Windows 2000 and Windows XP
Home/Professional.

does the 120 support 3rd party TAPI so that it
can be used with the TAPI client/server model?
When I did my resesearch on the subject about 2 years
ago, the TSPs had different names afair, so maybe
the situation has changed?

Matthias,
are you refering to the product names or the file name?
AFAIR the TSP file name (HcmO_3rd.TSP) is constant since the beginning.
Are you refering to MS TAPI client/server (with RemoteSP.TSP)?
If yes, then yes. Any TSP actually does because it really can't do something
against remoting.
A general restriction of MS TAPI client/server architecture is that media
streams are not remoted,
but in case of HT120/170 that's not an issue because they are for call control
only.
Regarding HT120 and remoting in particular: please note that this a 1st party
TSP, so you can only remote one single line device.
So it doesn't really make sense to remote it because you can install HT120 on
the client PC directly.
Furthermore you can install HT120 on several client PCs directly, and each TSP
drives one line on each PC.
You can use as much HT120 TSP concurrently _without_ licensing as there are
CSTA links in your HiPath PBX available.
Above this limit a "kind of" server component is used, the so called CSTA
Message Dispatcher (CMD), to concentrate the CSTA links from the HT120 TSPs to
one CSTA link to the PBX.
Licensing is required when using CMD.
CMD does _not_ require a server OS.
Matthias Moetje
> are you refering to the product names or the file name?

I meant the product names. I remember names like CorNet and
CallBridge, but I don't remember HT120 or HT170.

That's why I was talking about 3rd party TAPI drivers only.
If you want to get rid of the cablings and data adapters there
is just the 3rd party option.

Connecting HT120 directly to the PBX won't help here, too
because who has the PBX near his computer? And you still need
the cable (probably a long one...)
I didn't know about the CSTA concentrator, the pricing would be
interesting here to see if it is a more affordable alternative to the
HT170.
Another reason why I criticized the HT170 pricing is the fact that
other (while not all) manufacturers provide their TSPs for free...

Matthias,
AFAIR the product names are unchanged for several years now.
Prior to "HiPath TAPI 120 / 170" it was "Hicom CTI TAPI 3P" years ago.
I guess this renaming was triggered by the overall transition from Hicom to
HiPath trade names.

Well, to be precise the HT120 (although offcicially refered as 1st Party TSP
due to having only one line device) is IMO a 3rd party TSP because you can
freely configure which device (from all PBX extensions) you want to control
with it.
It does not necessarily have to be the phone next to the PC.
There is no direct link between HT120 and the associated phone, the model is
PBX-centric (as opposed to phone-centric e.g. with CallBridge 1st party TSP).

I guess I mislead you completely.
Actually it will help very much because the connection from HT120 to PBX is
not physical but only logical!
The CSTA link is simply an IP connection and therefore no additional cabling
required (presuming that the client PCs and the PBX are already connected to
the LAN).

The CMD is not a stand alone product but only part of HT120/170.
Sorry, I don't have these pricing details,
I'm "only" involved in TSP development, but not in licensing / sales /
marketing.
I suggest to contact a local Siemens dealer directly.
But as already said for some small number clients (upto 8, depending on PBX
type/version and presence/usage of other CSTA applications) HT120 can be
operating without licenses, i.e. it is absolutely free!

On the other hand I guess those other manufacturers "hide" the costs for the
TSP in the costs of the PBX.
E.g. when buying a new car some prefer a price including all "extras" with no
or little choices on epuipment, some prefer a detailed extra equipment (price)
list so that they can exactly choose what they like/need.
I guess not all PBX customers need/want a TSP.
One way or the other, in the end the development costs for a TSP (or the car
extras) have to be paid somehow... (by the customer).
