Many times during the morning after 4am, the system doesn't work- as in it doesn't take in incoming calls. I did a quick fix for this by telling the girls in charge of answering the phone to start the morning by doing a test call to the voip number and if it is not working then to restart the 3cx system. This always does the trick. We also experience this problem after the internet goes down (I understand why it happens during the downtime but after we reset the router and fix up the internet, the 3cx system needs a restart to get to work again and continue accepting incoming calls). Is there anyway we can prevent this from happening? We want to use 3cx on a large scale and maybe if everything is good then look into purchasing it for the business but we cannot seem to get over this hurdle.
