The Prestige 2602HW-L has all of the features of the Prestige 2602HW and adds the PSTN 
(Public Switched Telephone Network) lifeline feature. PSTN lifeline lets you have VoIP 
phone service and PSTN phone service at the same time. 

The following sections describe the features of the Prestige. 

The Prestige 2602HW-L has a LINE port for connecting a PSTN line. You can receive 
incoming PSTN phone calls even while someone else connected to the Prestige is making 
VoIP phone calls. You can dial a (prefix) number to make an outgoing PSTN call. You can 
still make PSTN phone calls if the Prestige 2602HW-L loses power.

A Ringer Equivalence Number is used to determine the number of devices that may be 
connected to the telephone line. The Prestige can support three devices per telephone port.

The Prestige has a built-in adaptive, buffer that helps to smooth out the variations in delay 
(jitter) for voice traffic. This helps ensure good voice quality for your conversations.

The Prestige complies with the following VoIP standards.

• SIP version 2 (RFC 3261)
• SDP (RFC 2327)
• RTP (RFC 1889)
• RTCP (RFC 1890)
