Phone Use and Configuration
This chapter describes basic phone setup and usage, as well as select advanced
VoIP configuration options for your ZyXEL Device.
3.1 PSTN Phone Set Up (P-2701RL Only)
When one of your VoIP accounts is registered, the ZyXEL Device normally uses the
Internet (VoIP) rather than the regular PSTN phone line to place and receive
phone calls.
However, if you connect the Line port to a regular PSTN phone jack, then
incoming PSTN calls will be forwarded directly to the phone connected to your
ZyXEL Device's Phone port.

3.2 Placing Phone Calls

Use the following sections to make outgoing calls from a phone attached to the
ZyXEL Device to another phone.
Follow these directions to make calls over the Internet:
• If you want to dial a SIP number that only uses numbers (for example,
"12345"), dial the number on your phone's keypad. You can also set up a speed-
dial entry, if you want, in the VoIP > Phone Book > Speed Dial screen. See
Section 3.4 on page 24
• If you want to make a peer-to-peer call, set up a dial plan with URL entry first.
Use the VoIP > Phone Book > Dial Plan with URL screen. Then dial the pre-
configured SIP number to make the call to a peer VoIP device directly. See
Section 3.5 on page 26
• If you want to call a PSTN phone over the Internet, follow your VoIP provider's
instructions.
