Inter connect Grandstream PBX with Fusion PBX

[Jiz]

HI,
I would like to inter connect Grandstream PBX with FusionPBX to route calls both direction. How do I achieve this ?
fusionPBX Should able to receive incoming SIP trunk registration so i can configure a SIP trunk in Grandstream to register with fusionPBX. fusionPBX is configured with public facing internet and Grandstream behind a firewall.

Thank you

I have a few dozen connected to my Fusionpbx servers. Here is how I do it.

Assume I have number 333-555-1000 as a main# and 333-555-1001-1010 as DID's and my domain is pbx.mypbxexample.com

In Fusionpbx,
build an extension for the other pbx (I typically use 10 digit main number of site since my carrier sends 11 digits)
So Extension # would be 3335551000

Then build a "bridge" under "Applications>Bridges"
Name: whatever makes sense to you
Destination: sofia/internal/sip:$1${regex(${sofia_contact(3335551000@pbx.mypbxexample.com)}|^[^@]+(.*)|%1)}
Description: optional

Build Destinations for the numbers 13335551000 - 13335551010
Destination 13335551000 route to extension 3335551000
Destination 13335551001 route to bridge <name from above>
Desitnations 5551002-1010 same as above. You could build a regex to match the range, but for smaller batches, I prefer to list each number in case the destination needs to change.

In Grandstream:
Build registration voip trunk as you would any other provider.
Inbound routes would need to match 3335551000 and whatever digits other provider is sending for other DID's in my case it would be 133355510XX

If you need examples of Grandstream side, let me know and can pull a few screen shots later.

Thank you very much Ad5ou for your important contribution.
I would like if you can publish the screen since I have to connect 10 Zycoo pbxip to my FusionPBX servers in the cloud and it would help me because they are similar.
From now many thanks and greetings.
