4.5PSTN Phone Line Configuration (P- 2301RL-P1 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 make phone calls. Use this section to set certain phone numbers (emergency services, for example) to always use the regular (PSTN) line. You can also set the PSTN line prefix number you enter on your telephone keypad before dialing a phone number. This prefix number makes the ZyXEL Device use the PSTN line for the call.
