This feature allows a user to take a call ringing on a phone of an employee by dialing a call pickup group number. This functionality utilizes the call park application.
However, it cannot be used for in the following scenarios:
- Calls to a user’s private line
- Calls from a contact to whom was assigned the confidentiality level Family and friends
- Video section of an audio / video call
- Calls from a simultaneous ring
- Calls delegation fashion
- Calls from a response group
Originally, the only way to configure this was by using the SEFAUtil tool. NO MORE YEY. However, you have to configure it using PowerShell.
Step One – Create a Call Pickup Orbit Range
Firstly we need to create a Call Park Orbit to use for pickup:
New-CsCallParkOrbit -Identity “Call Pickup” -NumberRangeStart 700 -NumberRangeEnd 799 –CallParkService “Service:ApplicationServer:yourfrontendpool.fqdn.com“ -Type GroupPickup
Step Two – Associate Call Pickup Number to Users
Now we can associate call pickup numbers to the users:
New-CsGroupPickupUserOrbit “Gareth Jones” -Orbit 700
This is difficult to manage so ensure you use this tool: https://gallery.technet.microsoft.com/office/Lync-2013-Skype-for-2b425b29
