Solved 3cx Client 15.5.345.642: ignores no vibration checkbox

[nobody]

When I start the program it makes the phone vibrate two times for no apparent reason. I unchecked vibrate in the advanced options, but no change.
Also, after a missed call again the phone vibrates four times.
Can this be fixed? Besides from the checkbox which has no effect, i see no reason for the program to vibrate at startup then that the programmer was proud of learning a new option he could annoy users with.
Or, is there reason for this behaviour?

We'll check this.

I have installed 15.5.345.643 on the sony. The Problem is gone. I thought the ony difference was the quit disabling push which is again availible in this version?
Anyway this topic can be closed.
