Enable Group Call Pickup for users and assign a group number in Skype for Business
Enable users for Group Call Pickup in Skype for Business Server Enterprise Voice, and assign a group number.
After you add call pickup group numbers to the call park orbit table, you use the SEFAUtil tool to assign the group numbers to users and enable Group Call Pickup for them.
In a hybrid deployment, do not assign a Group Call Pickup group to users who are homed online. Users who are homed online cannot participate in Group Call Pickup. That is, their calls cannot be answered by other users, and they cannot answer calls to other users.
To assign a group number and enable Group Call Pickup for a user
Log on to the computer where you installed the SEFAUtil tool with administrator rights.
At the command line, run:
SEFAUtil.exe sip:<sip address of user> /server:<pool FQDN> /enablegrouppickup:<group number>
For example, to assign group number 199 to a user:
SEFAUtil.exe firstname.lastname@example.org /server:pool01.contoso.com /enablegrouppickup:199
