Multi-Node Scenarios

The Communication Service supports single and multi-node MiVoice Office 250 configurations. Depending on the requirements of the customer there are two different ways to implement the solution in a multi-node scenario:

Multiple Communication Services with single-node licenses
Single Communication Service with a multi-node license

The benefits and restrictions of each method are outlined below.

The scenarios outlined below only affect Phone Manager usage, From release 5.0, if using any of the Call Reporting or Call Recording features, a license for each node is required.

Multiple Communication Services with a single Node License

Out of the box Communication Service can be configured to connect to a Mitel CT Gateway and provide users with device status information across more than one node. It will however only provide Phone Manager capability for a single node. If the Communication Service is configured to connect to a CT Gateway without a multi-node license then one of the nodes needs to be configured to be the node Mitel Communication Server is going to support Phone Manager clients on.

In this scenario each Node can have it's own Communications Service to support it's own Phone Manager clients.

Example

A company has two MiVoice Office 250 systems. Each system has it's own Communication Service providing Phone Manager connections for a single node. Both Communication Services are connected to a CT Gateway.

Benefits & Restrictions

Configuring the Communication Service in this way has the following benefits and restrictions:

Benefits

No Multi-site license needs to be purchased
Each site can configure of their own Communication Service
Minimal inter site traffic in a WAN environment

Restrictions

Users cannot Chat between Communication Servers
All configuration needs to be duplicated on each Communication Service, User & Business Units for example
Non of the Call Reporting or Call Recording features could be used
IP SMDR and Agent Hot Desking would only work for the default node

This configuration is usually recommended for scenarios where multiple nodes are installed at different physical locations.

Single Centralized Communication Service with License for each Node

To work in the this configuration the Communication Server must have a Multi-Node license applied, this will allow the Communication Service to support Phone Manager connections from all the nodes available.

Example

A company has two MiVoice Office 250 systems. A single Communication Service connects to both systems via a CT Gateway and provides connectivity for Phone Managers users on both systems.

Benefits & Restrictions

Configuring the Communication Service in this way has the following benefits and restrictions:

Benefits

Central point of administration
Chat between all users of the system
Call Reporting and Call Recording features can be used
IP SMDR and Agent Hot Desking would work on all nodes

Restrictions

Increased traffic in WAN environments
Less resilience to WAN connection loss

This configuration is usually recommended for scenarios where multiple nodes are installed at the same physical location.
