How to Configure SIP Trunk between FCM5600 with FCM5600 by using FRC

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 #

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:

  • 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.
