I today updated my client to 9.0.178.
With that update a new navigation gets established and manual dial out is only available from the "calls" context menu.
I don't think this is really intuitive and tried to deativate the "preview" checkbox. The manual dialer does not come back :-(
The "new" dial a number function also introduces the option to call an external voice participant - this is not working (for at least german landline as well as mobile numbers). Calls get rejected with a "not available" message. After this I cannot use the dialer anymore until logging out and in again.
Pls check this - thanks!
Beside that the dial comes up in English language although my client is set to German.
