I have successfully updated our PBX from version 12 to the latest version via a restore and have configured the server to run in a VM.
I have 25 Cisco endpoints and 5 remote workers and the old live version 12 server is currently sitting on our LAN in our standard IP range.
I intend on moving the endpoints onto the new server and changing from 3 x PSTN lines to 4 SIP trunks and wanted to know the best network solution. I have a linux firewall with multiple zones so i could put the PBX on a dedicated zone and not on the general IP range on a DMZ and use the built in firewall.
I have a TFTP server also on our normal range which i guess ill have to move to the new range?
I have read various opinions but wanted to get an exsperienced persons point of view.
