Intercepting outgoing calls

[vadiml1024]

Hello,

I'm thinking about ways to integrate VOIP calling with standard
Windows Mobile dialer

The basic idea is :

1) Intercept an outgoing calls and try to reach them via VOIP, if it
fails reissue the GSM call
The big question is: How to intercept the outgoing calls?

2) Write a TSP which handles incoming VOIP calls and generate correct
events for TAPI
The question in this case, how to make aware standard Window
Mobile dialer to execute lineOpen on
my TSP

Any ideas, pointers?
Thanks
Vadim

Vadim,
intercepting/redirecting outgoing call via a TAPI app isn't supported.
You can only monitor for outgoing calls (initiated manually or by another TAPI
app) and lineDrop() them.
But this of course will be noticed by the initiating app.

I guess you mean outgoing instead of incoming?

Please see the discussion "Redirect outbound call (Windows Mobile 5)" in this
newsgroup.

Andreas,

Thanks a lot for your input.
It seams that thread you've mentionned is coping with EXACTLY the same
issue as me.

Thanks

Vadim,

there are two other options:

- Windows Mobile 6 already has a mechanism for
making VoIP calls through the dialer

- The Windows Dialer can be extended with a dll
(see devices from E-Ten and older HTC devices)
or even replaced (newer HCT devices).

Manufacturers have used this extension mechanism
to support video calls (which do not go through the
cellTSP). I think this mechanisms could also be used
for making VoIP calls. Unfortunately I'm not sure if
it's possible to get documentation for this unless you
are a licensor of Windows Mobile...

Best regards,

Matthias Moetje
