Pickup is a common feature sip phones, it allows you to answer a call that is actually ringing on another phone. For this to work you need to monitor the other party via a speed-dial key. When propperly set up your phone will receive updates whenever the call-state of the monitored party changes. Your speed-dial key will start blinking red when the monitored device receives a call and is ringing. Also on colored models and on extentions the info-line of the key will update to show who is calling. Pressing the key in this state will lead to picking the call, i.e. answering on your device.
Each speed-dial key can publish it's pickable calls into a global pickup-list. That list collects all pickable calls from all keys that participate and shows them all in one screen. You can open the screen via the apps-menu or using the pickup key. We also have settings to open the screen whenever new calls are available (settings->telephony->...).
Pickup Feature Code#
Usually pickup is done via standard sip-techniques using a
replaces-header. Some pbx'es instead require the use of a feature code. Pickup is then done by calling said feature-code plus the number of the monitored party. The speed-dial keys will automatically switch to using a feature code when you set it in the pickupCode setting.
