Pick-UP and group Pick-UP

1. Service description

Pickup and group Call Pickup are features that allow a user to answer an incoming call that rings on a telephone or softphone other than the user own. This document explains how to configure and use the Call pickup and Group Call pickup features with miniSIPServer.

From version 2.5.4, miniSIPServer can support these features. You can download the latest miniSIPServer from our official website.

Below figure describes a simple scenario of pick-up service. In this scenario, Hong and G.T are in the same pick-up group. G.T number is 102, Hong' number is 101. When G.T receives an incoming call from Holly, Hong can pickup this call through two ways:

  • Hong picks up G.T' call directly. Hong can dial "*40*102" to miniSIPServer and miniSIPServer will transfer G.T's call to Hong. In this scenario, "*40*" is the default prefix of 'call pick up' and '102' is the target number which to be picked up.
  • Hong picks up a call in the same Pick-UP group. Since Hong and G.T are in the same pick-up group, Hong can dial "*50*" to pick up a ringing call from the group. In this scenario, the G.T's phone is ringing, so miniSIPServer select it to pick-up for Hong. We have to mention that miniSIPServer always pick up the first ringing user if there are several users are ringing.

In miniSIPServer, only the persons who are in the same pick-up group can pick up others' calls. If the user isn't in the same pick-up group, he/she cannot pick up the target user. For example, in above figure, Tom is not in the same pick-up group with Hong and G.T, so Tom cannot pick up G.T' phone.

2. Configuration

In above description, there are two prefixes for call pick-up features. The prefix of "call pick up" is "*40*". The prefix of "group call pick up" is "*50*". These prefixes are fixed in miniSIPServer.

The only thing need to be configured is the user's pick-up group. Follow below steps to configure it.

  • Please click menu "data -> local users" and edit or add a local user.
  • In the pop up window, please click "supplementary services" tab as following figure.
  • Then configure the pick-up group ID. The users with the same pick-up group ID belong to the same group and they can pick up the call for each other.


In our example, Hong and G.T belong to the same pick-up group whose ID is '1', so they can pickup calls for each other.
