MiVoice Office 250 Engineering Guidelines

OAI APPLICATIONS

Open Architecture Interface (OAI) provides a great deal of flexibility by allowing an external
application to customize system behavior for customer-specific behavior. With this flexibility
comes the risk of an OAI application adversely impacting system performance.
Each OAI Application has a different effect on system performance based on the type of
application. Combined with the OAI application type, the other factors that contribute to system
performance are call traffic and the number of devices. For a system with very low call traffic
or fewer than 30 total devices, system performance is not greatly affected regardless of the
application type or number of applications. The following guidelines are for systems with more
than 30 total devices or medium to high call traffic.

HEAVY APPLICATIONS

Some applications (e.g., Attendant Console, Unified Communicator Advanced, and Customer
Service Manager) monitor the statuses of almost every device in the system or deal with moving
calls throughout the system. These types of applications are considered heavy applications
and can affect system performance with medium to high call traffic.

LIGHT APPLICATIONS

Some applications (e.g., UC Express) only monitor and control a single phone. These types of
applications are considered light and do not affect system performance by themselves.

CT GATEWAY

CT Gateway is an application that runs on an external PC and provides the system with the
following functionality:
• CT Gateway can connect to multiple systems in a multi-node deployment to make a
multi-node system appear as a single node to a connecting OAI application. This function-
ality eliminates the need for an OAI application to be node aware so that it does not have
to manage the connections to multiple nodes and manage multi-node scenarios.
• CT Gateway offloads OAI processing from the MiVoice Office 250, thus allowing for more
heavy applications to connect to a single system.

OAI APPLICATIONS GUIDELINES

The following table defines the recommended number of OAI applications based on the
application type and call traffic. If the system exceeds the recommended number of connecting
applications, then the system should be equipped with either a CT Gateway or a PS-1.
