Hi I have had this a issue with call in/out issue on the 3CX system. I thought initially it was the PC (Pentium4) then asked cust. to provide a recommend version i3 pc but still experience the issue till I reboot the pc. All comes up fine and can call in/out. This happened just once but kept happening with old pc. The site is in Harrogate and hoping to fix it asap. Can't anyone help please?
