Installing and Configuring the Quintum
Tenor AS Gateway
Introduction
The Quintum Tenor AS is a 2-4 port analog gateway used in NetVanta Unified Communications Server
installations to provide a gateway between internal (SIP) phone calls and the outside phone network
(PSTN). Voice communications from an internal phone have voice over IP (VoIP) signals converted into
traditional analog voice, which is transmitted over the PSTN.
A gateway works in conjunction with the UC server’s SIP Proxy and SIP. All telephony services are
provided through the mutual cooperation of SIP gateways, SIP telephones, SIP proxy and the Core
Application Service.
The following diagram illustrates the UC server’s SIP architecture and its relationship with other
components in a typical customer network.
