Fusionpbx as a gateway server

[RTL]

I'm using Fusionpbx as a gateway server for some end users. Calls arrive on the fusion server and are then sent to the end users's pbx via the sip trunk app and it works well.
I'd now like to make calls go the other way. I can get calls from the end user's pbx to fusionpbx but can't quite work how to get that out through a gateway with the correct source and destination numbers. I'm pretty sure I need a bridge here but not clear on how to implement it. ANy help wpuld be appreciated.

IP authentication
Gateway PBX

• Create an extension for your PBX
• Add the IP address in the CIDR field of the extension.
• Status -> SIP Status, press the RELOADACL button

Client PBX

• Create an outbound route from the client PBX to the Gateway server
• Add the Gateway PBX to your providers access control list
• Add new numbers to inbound destinations

Registrations

Gateway PBX

• Use the SIP Trunks feature when you are handling registration from a client PBX
  • https://github.com/fusionpbx/fusionpbx-app-sip_trunks
  • This will add SIP trunks for each extension that will route the calls to the Client PBX

Client PBX

• Create a gateway that registers with the Gateway PBX
• Add the Gateway PBX to your providers access control list
