Hi, I've an issue with trapping CS Call notification events on a PPC running on Windows Mobile 5.0 First, the application is registered to recieve any CS Call notifications. Subsequently, PDP Context is established in the process of UMTS(3G) connection. Following this, no CS Call notificatation reaches our application. In case PDP context is not established, (i.e before UMTS is connected), the application is able to trap/recieve all CS Call indications. What could be the reason leading to this kind of behaviour?  Thanks.
