Avaya has upgraded its IP telephony gear to offer better support of Session Initiation Protocol, which for enterprises translates into more phone features and greater efficiencies in business VoIP deployments.

The upgrades include new software versions for some of Avaya’s VoIP platforms, as well as a new phone and media gateway.

Central to the improvements is a new version of Avaya Communications Manager with SIP embedded within it, which eliminates the need for deploying a separate SIP server when deployed with the S8300 media gateway. Version 5.0 of the software also enables SIP trunking, which can redirect multimedia IP traffic when networks become congested, improving performance and connection quality.

The new media gateway, the G450, is designed to extend Communications Manager capabilities to branch offices. The gateway can be purchased as an appliance or as a blade in a server. With dual processors and dual power supplies, it is more flexible and resilient than the G700. Pricing for the G450 ranges from $5,300 to $12,300.

In addition, Avaya added SIP to its Avaya Video Telephony Solution to let users create video calls as simply as they do voice calls and conference in as many as six parties. A video option is available for customers calling businesses via 3G mobile devices, video kiosks or PCs. With Avaya Interactive Voice and Video Response, customers can view visual menus for choosing options, watch instructional video or see ads.

There are also more SIP features in Avaya’s Call Center 5.0, which works with Communications Manager and supports features such as populating agents’ monitors with data that is relevant to customers who have called. Avaya says it worked with service providers so computer-telephony integration features supported by SIP match the features available via ISDN.

With a new SIP-enabled contact-center phone, agents have access to presence information that can help them determine whether subject-area experts are available to help answer customers’ questions, for example. Also, SIP trunking supports the ability to pass customer calls from contact center to contact center, so agents who handle calls also have customer-specific data available via their desktops.
