Linked Edge Controllers

Example of IC-EDGE Systems interconnected by Edge Link

Linked Edge Controllers makes it possible to call between different IC-EDGE Systems. The routing between IC-EDGE Systems are easily configured in the Edge Controller Directory.

Prerequisites

Software Requirements

The Edge Controller must be a station in the Turbine family with software version 5.0.3.0 or higher.

License Requirements

No license is required to use Edge Link.

Network Port Requirements

The following ports must be open in the IP network:

• UDP port 5060 for SIP
• UDP port range 61000-61250 for audio

If system includes TCIV and video calls then the ephemeral UDP port range 32768-60999 must be open too.

Supported features

• Point to point calls with Caller ID
• Door opening
• Call transfer
• Call forwarding
• Ringlist
• Station profiles

Configuration

Edge Link Routes must be configured to enable calls between different Edge sites. A route consists of:

1. Directory Number range (To - From) in the remote site
2. Logical name for the route
3. IP address and SIP port of the remote Edge Controller (Edge Controller SIP port is normally 5060)
4. Profile to assign calls coming from/to the route. Profiles can be used to restrict access to/from a route

Transit calls are not possible. There must be a direct route from the calling Edge site to the remote Edge site

To add a route on an Edge Controller, select Edge Controller > System Configuration > Directory

Edge Link route configuration

• Number Start: First number in the remote IC-EDGE System.
• Number Stop: Last number in the remote IC-EDGE System. The number range must have the same amount of digits. For example 200 - 299, not 50 - 150.
• Name: Logical name for the route. Any text can be used.
• Profile: Profile to assign calls coming from/to the route. Profiles can be used to restrict access to/from a route.
• Host: IP-Address of remote Edge Controller
• Port: The SIP port used. Normally 5060.

Configuration example

IC-EDGE system 1

Name	Saturn
Edge controller IP Address	192.168.1.10
Numberplan	40-80

IC-EDGE system 2

Name	Venus
Edge controller IP Address	192.168.5.10
Numberplan	120-160

IMPORTANT INFO REGARDING MULTIPLE IC-EDGE SYSTEMS ON ONE LAN IP SUBNET
Because of the Edge auto-detect and configuration, it is NOT recommended to run multiple IC-EDGE Systems on the same LAN IP-Subnet. 
If you still, despite our recommendations want to run multiple IC-EDGE Systems on the same LAN subnet, we strongly recommend that you 

 -Connect and set up IC-EDGE System 1
 -Disconnect IC-EDGE System 1 
 -Connect and set up IC-EDGE System 2
 -When done with all separate configuration, connect both IC-EDGE Systems.

If you are going to do configuration changes, please remember to disconnect the other IC-EDGE System from the network.

Limitations

• Edge Controller can have maximum of 50 configured Edge Links.
• Transit calls: A client may only call to sites to which there is a direct route. In the example in the top of this article, the satellite Edge sites may only call to central site, while central site can call all sites.
• Call Transfer/Forwarding can only be done to stations to which there is a direct route.
• Group calls: It is not possible to do group calls from one Edge system to another.
