Abstract
In an embodiment of the method for handling subscriber input during interswitch handover of a call from a first switching station to a second switching station, DTMF digits received at the second switching station are sent in a message to the first switching station. The first switching station then performs an operation on the received digits such as playing the DTMF tones to a network or triggering a service.
