2. Also tell us what kind of call this is: extension to extension, external call to extension, Queue call to extension, Ring group call to extension?

 

[holleman]

sorry connnected bij direct sip

 

[holleman]

external call to extension that is forwarded (DND) to external extention2
Internal not tested yet.....but considered the configuration i don't think it will change anything

 

[holleman]

Version standaard 16.0.8 ...I will upgrade this weekend Thought I'd allready done that

 

[JohnS_3CX]

Is the W60B running firmware version 77.85.0.25 ?

You can find it here if you click "Software" on top

BTW: Hyper-V Debian

 

[JohnS_3CX]

Debian on Hyper-V must absolutely use the NTP service. Please read here and make sure it is installed:
https://www.3cx.com/docs/installing-microsoft-hyper-v/#h.cjj20zk71lns

Also please confirm the firmware version of the W60B, this is important

 

[holleman]

Thats the sollution. I allways assumed that it was installed by default...Or is that only in the windows version?

 

[JohnS_3CX]

Not by default, you have to do it manually if you will use a Hyper-V host because there is a lot of time-drift there for some reason.

Is the problem solved entirely now?
