I am after assistance with configuring a 3CX (which is great by the way - thanks!) and a Vegastream 400 gateway. My problem is with CLI. Config in brief: ISDN30 --- Vegastream 400 --- LAN IF -> 3cx (nothing complicated about that) Dial plans all work - I can make and receive calls both internally and externally. I am using Polycom 330 phones and the latest version of 3CX. When I monitor the Vega, I can see the CLI tag coming through from the ISDN. -- What do I need in my dial plans to pass the CLI through to 3CX? -- What do I need to do in my 3CX system to see the CLI on the Call Assistant and/or the phones? -- Do I need to give any further details for any one to help? Any assistance is greatly appreciated! TIA.
