Alcatel - TAPI - C# Driver hangs

[BizTalk Architect]

Hello,

I am days into this problem and I cant make heads or tails of it.

Please post suggestions, I dont care how crazy they sound.

Scenario:


I have a TAPI C# application. (TAPI 3.0)

Driver is an Alcatel TAPI Service Provider v. 5.0.46.003 with an Alcatel
PBX unit.

The application will never initalize unless I run the Pimphony application
FIRST (which ships with the application)

If I try to initalize the appplication without the Pimphony application
started, it will never initalize. If I then try to start Pimphony, it will
never start. Only when I re-boot will Pimphony start again.

Even if you dont use the Alcatel brand and have encountered a similar
problem, please let me know..

I cant understand why this just wont work. Please help.

Well, I'd suggest getting a copy of the MS TAPI Browser and testing to
see if it can open the line(s) involved. If it fails then you know it
is something funky on the Alcatel side.

I'm not really following what the role of "Pimphony" is...

Also, is the application yours? If so, are you opening the lines with
OWNER as well as MONITOR privileges?

Grant,

I already have the TAPI browser, which works correctly. I didnt mention it
so as not to add any
more complexity to the scenario. Basically the same is true for the TAPI
Browser as for "Pimphony". Pimphony is a little client app that came with
the PBX. I lets you make calls and answer them, et al from a pc across the
network. It sort of seems like these apps are able to get TAPI going, but
not C#....

What do you mean exactly by "it will never initalize"?
What HRESULT do you get from ITTAPI::Initialize()?
Please post the relevant code for review.

Regarding TAPI and .NET see KB article "841712 - Telephony Application

Thanks for the reply.

After some further investigation, I have determined the code is stopping
when "RegisterCallNotifications" talkes place.
// connect the event to the handler on the object and store the token
received

gCallNotificationToken =
parentObject.gTapi.RegisterCallNotifications(gAddress, true, true,
objMediaSupport.MediaTypes, 0);


//gCallNotificationToken =
parentObject.gTapi.RegisterCallNotifications(gAddress, true, false,
objMediaSupport.MediaTypes, 0);

I tried setting fOwner to false and it had no effect....

Any ideas?

Thanks again....

What MediaTypes are you using?
What about providing a lCallbackInstance?
From MSDN: "Callback instance to be used by the TAPI 3 DLL. Can be the
gulAdvise value returned by IConnectionPoint::Advise during registration of
the ITTAPIEventNotification outgoing interface."

Can you reproduce this with TAPI Browser TB3x ?
If so, please post a TB3x log.

Hello again, and thank you.

Media type is TAPIMEDIATYPE_AUDIO

No I cannot reproduce this behavior on the Tapi browser. It works normally.

I tried an lCallbackInstance = 1 which had no effect -- is there another
value I can place here? I read the MS page you sent but I cant determine
whether I need those values or not.

Well, now the confusion grows....

What has worked in the past is no working....

Here is the log from the TAPI Browser:

What happens if you use fMonitor = true ?
What happens if you use lCallbackInstance retrieved by ::Advise() from
ITTAPI_6 ?

What happens if you use fMonitor = true ?

Same thing happens, it hangs forever trying to create the call notifications

What happens if you use lCallbackInstance retrieved by ::Advise() from
ITTAPI_6 ?

I am not sure what you mean by "::Advise() " or how to impliment it.

Can you explain this a bit?

Thank you !

Andreas,

Thank you, and I didnt mention, your FAQ was very helpful.

I gave up. I grabbed a server, installed w2k, vs.net 2003 and I dont have
any more problems.

I wish I could put a finger on my problem for the public info, but I cant.

Thanks again.
