Avaya SIP solutions

Session Initiation Protocol (SIP) is an endpoint-oriented messaging standard defined by the Internet Engineering Task Force (IETF). SIP is a text-based protocol, similar to HTTP and SMTP, for initiating interactive communication sessions between users. Such sessions include voice, video, instant messaging, interactive games, and virtual reality.

As implemented by Avaya for Communication Manager release 3.0 and beyond, SIP "trunking" functionality is available on any of the Linux-based servers (S8300, S8400, S8500 or

S8700-series). SIP trunking allows Avaya Communication Manager to communicate with SIP endpoints and gateways across an IP network. SIP trunks allow an enterprise to connect its server(s) to an Avaya SIP-Enablement Server (SES), a SIP-enabled proxy server, and through this proxy to an external SIP service provider, if desired. The trunk support in Communication Manager complies with SIP standards, specifically IETF RFC 3261, and so interoperates with any SIP-enabled endpoint/station that also complies with the standard.

Avaya Communication Manager supports SIP endpoints, including the Avaya 4602 SIP Telephone and Avaya IP Softphone Release 5. In addition to its IP telephony capabilities, IP Softphone R5 also includes Instant Messaging (IM) client software, which is a SIP-enabled application that connects to the SES for IM control. By means of having SIP-enabled endpoints managed by Communication Manager, many features can be extended to these endpoints.

Avaya SIP application enablement

Avaya Communications Process Manager is middleware software that uses customizable web services to integrate Avaya communications solutions into customer business processes. Communications Process Manager achieves this integration by detecting events from a customer business application. Different events trigger Communications Process Manager to invoke different communication applications to escalate the situation to people and resources that can address it.

Communications Process Manager performs the following functions:

Integrates the following Avaya communication resources. This integration makes it possible for the resources to communicate with Communications Process Manager and ultimately with each other.

-Communication Manager — provides telephony capabilities.

-SIP Enablement Services (SES) — serves as the SIP proxy. All communication resources use SIP to communicate through Communications Process Manager.

-Meeting Exchange Express — provides audio conference capabilities.

-Voice Portal — provides interactive voice response (IVR) capabilities for phone interactions between Communications Process Manager and its users.

Orchestrates interactions between the communication resources.
