#### Step by Step Instructions

Main VTO Setup (SIP Server)

1. Find the VTO you would like to make the Main

1. Review the settings and make sure Group Call is enabled

Villa Call No. : This indicates the Room No on the VTH it will reach out too No. : No. is the VTO Number. It can be changed when SIP server is disabled Group Call: This will call all VTHs on the same Room No family including Extensions
