Before You Begin; The Sip Settings Screen - ZyXEL Communications P-2612HW-F1 User Manual

See Section 10.13 on page 208

10.1.3 Before You Begin

• Before you can use these screens, you need to have a VoIP account already set
up. If you don't have one yet, you can sign up with a VoIP service provider over
the Internet.
• You should have the information your VoIP service provider gave you ready,
before you start to configure the ZyXEL Device.

10.2 The SIP Settings Screen

The ZyXEL Device uses a SIP account to make outgoing VoIP calls and check if an
incoming call's destination number matches your SIP account's SIP number. In
order to make or receive a VoIP call, you need to enable and configure a SIP
account, and map it to a phone port. The SIP account contains information that
allows your ZyXEL Device to connect to your VoIP service provider.
If you want to make only peer-to-peer VoIP calls, there is no VoIP service provider
involved, so the SIP account information does not have to match a real VoIP
service provider's SIP account. You can make up the SIP numbers. However, you
should still activate a SIP account and configure its number and map it to a phone
port, so that the person you call knows what SIP number you are using and the
ZyXEL Device knows to which phone port it should forward an incoming VoIP call.
You must use speed dial to make peer-to-peer VoIP calls.
