Hi! I'm new here so please forgive me if this been asked and answered before. I used the search option but it says my key words are to common to use to search, and i also used google search but nothing. I think a customer installation is a bit screwed up. I upgraded from v9 to v10 yesterday and changed all the Grandstream 2020 phones provisioning url's to use the 3CX server (it was not set this way before). Now when they get an external call it always plays the "You have a call from xxxxxx". If i read the manual corretly that message should be available when routing to external phone, e.g. mobile phone, and i can't find anyway to disable it. Is the installation bad? Or is there a way to fix this?
