Productivity can involve many tasks besides answering the phone. In times when you are too busy to receive calls, simply activate the Do Not Disturb (DND) feature. Your phone will stop ringing and calls will be sent directly to voicemail, allowing you to review them at a time when you are less busy.
All the versions of the TeleConsole support DND mode. See insturctions for web, Android, iOS, or Desktop for Windows.
If you are using a physical SIP phone you can set up DND on it directly. We have instructions of how to do this for all the phones we support (as well as discontinued ones) on this support portal. For a complete list of phone user guides access the portal home page (by clicking the Telebroad logo on the top-left or by following this link) and select the Telephone User Guides button.
