LanScape VOIP Media Engine
SipSubscriptionNetworkError
The SipSubscriptionNetworkError
event is sent to application software when the telephony engine detects
a fatal network error when it attempts to transmit event subscription
information.
This event will also be sent to the application
if the network cable gets unplugged during normal SUBSCRIBE operations.
When an application receives this event, the media engine event callback
procedure SIPCALLBACKPROC will have
a non zero value assigned for the pEventData parameter. This value is
a pointer to the SUBSCRIBE_RESULTS
structure which contains additional information for this event.
