How to have my Grandstream PBXs communicate with one another?

Q: I have 3 Grandstream PBXs on one network including One UCM6208 and two UCM6204. All in the same IP pool each ending in 192.168.0.210, .211, .212. Is there a way to have extensions from each of the PBX’s call the extension on the other PBX’s directly?

A: You will need to create a SIP trunk to communicate these devices to one another. And yes, one GS UCM can call other extensions. Click Here for the configuration guide!
