Hello,
Our recording application connects softphone extensions via service observe to get the audio streams of monitored calls.
On one hand, we are listening to call control events to get informed about call flow on a monitored physical extension.
On the other hand, we are listening to media events to get informed when the softphone joins the call and starts streaming audio.
Usually the EstablishedEvent originated from the monitored physical extension and the MediaStartEvent originated from the softphone are arriving nearly at the same time.
Now we've seen some scenarios, where we've only got CallControlEvents, but no MediaControlEvents.
This behaviour happened in two independent installations.
Unfortunately, this issue is not really reproduceable. It may happen, that one call is signalized correctly and the next call does not sent any MediaControlEvent.
Both installations are running with AES V4.2.3.
Is there a known issue with missing MediaControlEvents or Service Observe malfunction?
Is there a way to check, if Service Observe is working correctly?
Regards,
Claus Suffel
