P-2002, VoIP ATA

P-2002L, VoIP ATA with PSTN Lifeline

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.

VoIP Analog Telephone Adapter  

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.

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. 

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. 

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.

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.
