P-2602HWNLI Quick Start Guide

7

Note: You should have a voice account already set up. 

When one of your VoIP accounts is registered, the P-2602HWNLI normally uses the Internet (not the regular 
phone line) to make phone calls. Follow the directions in this section to make sure you can also use the 
regular phone line while one of your VoIP accounts is registered.

Note: When the P-2602HWNLI does not have power, only the phone connected to the 

PHONE 1 port can be used for making calls. Ensure you know which phone this is, so 
that in case of emergency you can make outgoing calls. 

In the main screen, click VoIP > PSTN Line (or ISDN Line if you want to configure for an ISDN phone).

1 Select the SIP server profile of your 

VoIP service provider, either SIP 
Profile 1 or SIP Profile 2, and click 
Apply. If your VoIP service provider is 
not in the list, select None and click 
Apply.

2 Fill in the fields with information from 

your voice service provider. Leave the 
default settings in fields for which no 
information was provided (except if 
otherwise specified).
If you have a SIP account like 

1234@VoIP-provider.com

,“1234” would 

be the SIP Number and “VoIP-
provider.com” would be the SIP Service 
Domain.  
This screen configures SIP account 1. 
Select the check box if you have a 
second SIP account that you want to 
use.

Note: If your selected a preconfigured SIP profile, just enter your SIP number, user name and 

password. Leave the remaining fields at default.
