Hi
under SIP (RFC 3856) a scheme exists by which it is possible to tell from a
central repository on a telephone network what the presence state of any
given telephone is (e.g. available, busy, do not disturb etc). This is
useful information for a console attendant application to know before call
transfers are attempted.
Short of using a TSP against every telephone on a network is there a way to
achieve this under TAPI?
Thanks in advance
Mart

Mart,
with TAPI you need to monitor (lineOpen() with LINECALLPRIVILEGE_MONITOR) each
device that you are interested in.
A 3rd party TSP is required to get the stati of multiple devices of a PBX.

Hi Andreas
calling lineOpen does not in itself return the state of the phone,
presumably I would need to wait for an change of state and note the device
state event? Or is there a TAPI method I can call?
Looking a little closer, I note that with Cisco Call Manager the way the TSP
is organised only a small number of devices are are usually configured (i.e.
usually those which an operator would be using, so around a maximum of 10).
As I understand it, this means that using the lineOpen suggestion it would
only be possible to monitor those few devices. Is there any mechanism under
TAPI which would allow the status of a telephone on the network which is not
confgured against a TSP, to be recovered. Registering thousands of TSPs
instances (one per corporate telephone) is not going to be practical.
Thoughts please.
Thanks
regards
Mart

Mart,
lineOpen() starts monitoring.
Depending on the TSP you will get initial state messages (e.g. of a call
currently being active).
In any case you will get messages on new call that occur after monitoring has
started.
You can enabale additional messages via lineSetStatusMessages().
Try it with TAPI Browser TB20 before starting to code anything yourself.

Exactly,
each device has to be lineOpen()ed with it own dwDeviceID.

No.

What's your exact scenario?
Do you have thousands of client PC on the corporate LAN (each with an
associated telephone)?
And do you want to be able to get the status of all phones at all PCs?
Then you would like to use the MS TAPI client / server architecture.
You only need one 3rd party TSP (for your PBX) running on a Telephony Server.
All client PC become Telephony Clients and have access to the TAPI devices
that are assigned to them.

That's interesting. The problem is that we cannot guarantee that every phone
is associated with a computer. Also, some computers might effectively be
associated with more than one phone.
Thanks for your suggestions anyway.

Mart

Mart, you are welcome.
Please note that you do not need a 1:1 reltion between phone and PC/user.
This would only be the most common configuration.
Sorry if this was misleading
Actually you can assign any TAPI device (driven by the TSP on the telephony
server) to any user (telephony client PC) on the network.
You can assign multiple TAPI devices to the same user.
You can assign the same TAPI device to multiple users.

Mart,
the truth is that TAPI does not really support presence information
like it is used in IM or other SIP applications.
The only states you can get are:
- ITAddress::State (AS_INSERVICE or AS_OUTOFSERVICE)
- ITAddress::DoNotDisturb (True or False)
- ITAddress::MessageWaiting (True or False)
Best regards,
Matthias Moetje
