Hi,

I've struggling a few days with a bizarr situation.
I've a cf smartphone application, that stablish a tcp connection trough
a GPRS connection with a TCP Server. When the application is running if
an incomming call is received is not displayed in the smartphone, and
the caller is receiving the calling tone.
I do not know what is wrong ?
What i can do to avoid missing the incoming calls ?

Some info related to the implementation:

1) TCP implementation using Async Sockets (BeginConnect, BeginReceive,
BeginSend etc)
2) All the UI calls ( basically some textboxs) are updated using a
ControlInvoker class called from the callback methods.
3) Events are received each 3 seconds, server sends a packet each 3
seconds, and the result is displayed in a few textboxs.
4) The connection is stablished when application is started and is
closed when the application is terminated.

Advices will be much appreciated

Thanks
Tiago
 
My understanding (I might be wrong) is that when packet data is actually
transmitted, the incoming calls are not received. If you simply keep the
connection, it's not a problem, but since your packets are sent/received
every 3 sec, it might be causing missed calls.
 
Hi Alex,

Thanks for your input, but how that issue can be avoided ?
Is there away to subscribe calls notification ?


Thanks
Tiago
