[Freeswitch-users] Two PBXes under one public IP address

[Kristian Kielhofner]

This is where domains come in...

You could have a SIP proxy sitting in front of any number of PBXs
redirecting requests based on domain.  Alternatively you could have
FreeSWITCH do this for you; either as a separate box or all on one
with some work in dialplan and a Sofia profile.
