Phone not hanging up after line is closed.

Hello,

I have a fresh install with latest updates.

When i use ring group or extension as destination, the caller calls and when he hangs up so does the line. Generally everything works fast and as it should.

When i use ivr i get a delay of about 15 seconds until the line is closed. This happens even if the call isn’t picked up. Extension keeps ringing for about 15 secs after the caller has stopped his call.
