Thanks Michael. That sounds perfect. I am thinking though that the SIP trunk does not really need to go through the VPN e.g. no NAT problems as its on the external Astlinux addresses. The only traffic going through the VPN is the console extension traffic (and BLF).
What do you think?

Im losing my hair. > > Regards > Michael Knill Hi Michael, I have a customer with a similar setup: one main office with 4 branch offices. Every site has its own SIP trunk to an VoIP provider for outgoing calls. Most incoming calls are going through the main office with has 3 queues. Each branch office has an OpenVPN client connection to the main office and a SIP trunk to the main office. The important point is: the host (IP) of the main office SIP trunk in the branch offices needs to be the virtual VPN IP address (e.g. 10.8.x.1) not the LAN address! All SIP endpoints (of the branch offices) can login as agents into each of the 3 queues of the main office. That works fine in combination with FOP2. Prosody is needed for distributed device status (if needed). I never had any routing or NAT issue.
