The VoIP Security section of the VoIP Options tab configures which Pin Codes can be used for authentication when paging via a VoIP Extension with the Pin Access option configured. Pin Codes are set up in the Pin Groups window found within the Universe Properties. If a Pin Code has been created in the Pin Group window, it will populate the VoIP Security window and can then be enabled by selecting the checkbox beside the Pin Group Name.
The Additional VoIP Routes section is used to add extra network routes that allow the MS-1 to communicate with VoIP servers and end-points on different Subnet's. Each additional route will require the destination network to be specified using the Network, Subnet and Gateway fields. Up to 10 additional VoIP routes can be added. Additional VoIP Routes can only be specified if the Use Dedicated VoIP Network Connection (LAN-3) is enabled on the MS-1e General Settings tab.
