Edge groups overview


An Edge Group is an association of Edges that enable a collection of network devices to communicate on a low latency LAN or a WAN, when required. (See Local site routing for Edge groups in this article.)

Edge Groups provide the following benefits:

  • All the phones associated with each Edge communicate with all of the other phones in the Edge group. 
  • Members of an Edge group share endpoints. For example, all of the phones in the same Edge group can access a SIP trunk plugged into one Edge in the group.

Shared Resources in an Edge Group

  • Phone trunks:  When you add an Edge to an Edge Group, that Edge inherits phone trunks added to the Edge group.
  • Communication providers:  When one Edge in the Edge group has a connection to a communication
    provider, all of the other Edges in the Edge group can share the resource.
  • External Gateways:  When one Edge in the Edge group has a connection to an External
    gateway, all of the Edges in the group can share access to the gateway.
  • Other communication providers:  Other communication providers can include WebRTC,
    SIP carriers, and Voice over IP gateways. As long as any of these resources
    have a connection to one Edge in the Edge group, all of the other Edges in the group
    share them.

Edge group setup is is detailed in Create an Edge group with a phone trunk.

Note: Edge groups do not share resources with other Edge groups.

Local site routing for Edge groups

Local site routing improves call routing and Edge utilization for multi-site implementations. When possible, the system routes calls through local, same site Edges to save bandwidth and reduce latency.

PureCloud is designed to use Edges within the same site if possible. PureCloud will only use Edges in other sites if the Edges on the local site are offline, are already at capacity,  or if the required resource, such as an agent, a station, or trunk is only available on an Edge located on a different site.
