Prestige 2002L VoIP Analog Telephone Adapter
ZyXEL’s P-2002 is an Analog Telephone Adapter (ATA) that provides customers with an easy-to-use solution for Voice over IP service deployment. Connecting a traditional phone set to the POTS phone port of the P-2002 series instantly establishes an IP phone device, allowing users to place VoIP calls without the use of a PC. Based on industry standard SIP (Session Initiation protocol, RFC 3261) call control protocol and sophisticated voice compression technology, the P-2002 series offers smooth IP-based voice communication with superb sound quality. ZyXEL’s P-2002 series Analog Telephone Adapter is an ideal solution for IP Telephony service deployment as well as SOHO and Home VoIP applications.
Supports Open Standard
ZyXEL’s P-2002 series supports standard SIP (RFC 3261), which is suitable for IP telephony service deployment and addresses the needs of users who are connecting to emerging SIP-based communication networks.
Easy to Deploy
ZyXEL’s P-2002 series supports multiple methods of configuration including Web-based configuration, Telnet management, and TFTP Auto-Provisioning. It eliminates the time and effort associated with complicated installation procedures.
Multiple SIP and Voice Channels
Based on ZyXEL’s flexible VoIP technology platform, one or more SIP phone number may be configured with the P-2002 ATA. Each SIP phone number can be freely assigned to either phone port individually, or to both ports at the same time. By using the P-2002 ATA to deploy VoIP service, service providers need only provide a minimum of one SIP number to each subscriber. Billing and service deployment are simplified by allowing subscribers to use two phones with the same SIP number. If one telephone is in use, users may use a secondary telephone to place a call while using the same SIP number. Additionally, users may also receive incoming calls even when the SIP number is in use. The advantages of the P- 2002 ATA include increased traffic and service revenue.
Cost Effective
ZyXEL’s P-2002 series turns a traditional phone into an IP phone device at a very low cost. Not only does the Prestige 2002 series deliver VoIP service at a low per-port cost but the built-in two-port Ethernet switch also allows user to connect their PC to the reserve Ethernet port without adding an extra Ethernet switch or hub.
Lifeline Support (Option, P-2002L)
ZyXEL’s P-2002L allows users to maintain PSTN phone service and VoIP service at the same time. When ATA power down occurs or VoIP service is not available, outgoing phone calls will be relayed to PSTN automatically. When VoIP service is active, users can place calls to a PSTN phone by dialing pre-fix numbers. Emergency calls or important calls can be relayed to PSTN automatically.
