Firstly, may I say that 3cx is great. This is my first go at setting up a PBX system for my work and we are loving it. However... Can someone help me on the following two issues. 1. I have set up a remote client using the 3cx phone at home by using a tunnel on port 5090 and all works well. However, when the phone is not being used there is a constant use of bandwidth that adds up to about 2mb a minute. When a call comes in it jump up even higher which is to be expected. My concern is that it is using 2 mb a minute when the phone is sitting there doing nothing. Please help reduce this use of bandwidth. 2. The 3cx assistant. Works well and shows me what calls are coming in and out etc. However none of the features, call parking etc are ever available to be used. They are always greyed out, even during a call or when a call comes in. I can't drag and drop anywhere. Is this normal?
