Separate SIP - Separate Company - Same 3CX server

[CRM250]

Hi all i hope someone can advise me on the best way to achieve the following

Currently running 18 on prem with a single SIP incoming that rings the Digital Receptionist and then calls are routed to one of two ring groups - it works perfectly.
However i need to cater for the following
Another SIP (same ISP so might need to work out how to juggle the pecking order and routing inside 3CX to skip an attendant)
There is also 4 new users that need to be stand alone and isolated from the rest of the system, so unique extension numbers etc, but no call groups needed as yet, but when using the 3XC desktop app or a phone i need to be able to hide the existing address book and other users / phones from the main company.
Having their own address book to populate is cool but hiding the one from the other company is a must.

Tips very much appreciated. and thanks in advance

StartUP....

You can edit Parameter Settings, specifically MULTICOMPANYMODE to 1.

This will isolate extensions groups between each other and then you can use groups/inbound routing for the rest.

Note that this parameter might stop working if 3CX decides to keep StartUP in their cloud only.

I am taking a look at the StartUP offering, this may suffice to be honest and keeps it clean.
thanks all
