To establish connectivity between IP-PBX (A) FCM5600 and IP-PBX (B) FCM5600, we need to create a direct link between the two systems. This will allow extensions on both sides to communicate with each other seamlessly. By using FRC (FIBERME Remote Connect), the extensions on both IP-PBXs will be able to make calls without requiring the systems to be on the same LAN, as the connection will be handled through the cloud.
IPPBX (A)
Model: FCM5600
Extensions Range from 1000 to 1009
IPPBX (B)
Model: FCM5600
Extensions Range from 2000 to 2009
NOTE!!!!! : Ensure that the extension numbers on both IPPBX are different. #

1- CONNECT FCM5600 TO FCM5600 USING PEER SIP TRUNK #
1.1- Create SIP Trunk on FCM5600(A) #
Log in to the FCM5600 (A) web interface.
From the web GUI, navigate to
PBX Settings → Extensions/Trunks → Trunks, then click Add to create a new trunk.
Configure the trunk as a Peer SIP Trunk to establish direct communication between both FCM5600 systems.

Peer SIP Trunk Configuration (FCM5600(A) ↔ FCM5600(B)) #
To establish a peer SIP trunk between two FCM5600 systems, configure the trunk using the following parameters:
- Name:
5600 (any name)— you can assign any identifier to distinguish the trunk. - Type:
Set to Server Mode. - Authentication:
Enable authentication. - Out Proxy Server:
Enter your FIBERME cloud domain (e.g.,yourcompanyname.fiberme.cloud). - Out Proxy Port:
5162 - Username:
5600(must match the trunk name exactly). - Password:
5600(same value as the trunk name for this configuration).
Ensure all parameters are correctly applied before saving the configuration to establish a stable peer connection between both FCM5600 systems.

– Transport Protocol: TLS
– From Domain:
Enter your FIBERME cloud domain (e.g., yourcompanyname.fiberme.cloud).

A new trunk has been configured.
1.2- Create SIP Trunk on FCM5600(B) #
Login to FCM5600 web GUI.
On FCM5600 web GUI, to create a peer SIP trunk, navigate to “PBX Settings-> Extensions/Trunks -> Trunks” and then click “Add” to configure a new trunk.
