why & when AES sends csta monitor end event - CSTAMonitorEndedEvent
We had written a c++ server application which uses TSAPI API's - registermonitor VDN and subscribe unsolicited events.
Doc reference: Avaya Aura® Application Enablement Services
TSAPI for Avaya Communication Manager Programmer’s Reference
Release 6.1

Monitor Ended Event — CSTAMonitorEndedEvent
The switch uses this event report to notify a client application that a previously requested Monitor Service has been canceled.

Our application was working fine without any problem but all of sudden it receives CSTAMonitorEndedEvent.
Do we know why & when AES sends CSTAMonitorEndedEvent? & How to recover from this situation.?
Is there any reason why AES is canceling the Monitor Service.?

CSTAMonitorEndedEvent is sent by PBX to inform an application that a
domain-control association has been terminated because the domain was removed or
changed to become an invalid domain by administration.

There can be other reasons as well like CTI link drop between AES and CM, etc. To get exact reason you might need to take MST on the CM that why Domain control has been ended.

To recover out of it your application should try to set up another/new monitor for same device. So if the device is valid and in correct state then CM will allow to set new monitor.
