In-Depth Look at PBX VoIP Functionality

Hot Desking

Hot Desking allows you to go to another PBX VoIP phone in your customer's domain, dial a special code number and after authentication, your calls will be directed to that phone. Outbound calls will be identified as your extension and not the phone you are hot-desking from.



The "barge" PBX functionality feature allows designated extension(s) to intercept another extension user's call and talk to both parties. The "listen" feature allows designated extension(s) to tap into an existing call and listen to the call. The "teach" feature allows designated extension(s) to tap into an existing call, listen to the call, and speak with the extension user without being heard by the other party.
