Application Notes for Configuring SIP Connectivity Between Avaya Voice Portal and Avaya Communication Manager Using Avaya SIP Enablement Services - Issue 1.0

This paper describe how to configure SIP connectivity between Avaya Voice Portal (VP) and Avaya Communication Manager using Avaya SIP Enablement Services (SES). The configuration consists of an Avaya SES home server functioning as a SIP proxy/registrar server with SIP trunking to Avaya Communication Manager. Avaya VP is a web-based and speech enabled interactive voice response system that is configured as an adjunct system on the Avaya SES home server. Secure SIP connectivity is achieved by utilizing Transport Layer Security (TLS) as the proxy transport for SIP signaling between Avaya Communication Manager, Avaya SES, and Avaya VP. In addition, this paper describe how to configure media encryption using Secure Real-Time Protocol (SRTP) to enable secure communications for self-service customers.
