PSTN Line Pre-fix 

Number

Enter 1 - 7 numbers you dial before you dial the phone number, if you want to 

make a regular analog phone call while one of your SIP accounts is registered. 

These numbers tell the ZyXEL Device that you want to make a regular phone call.

Line

Enter phone numbers (for regular calls, not VoIP calls) that you want to dial

The number (1 - 9) is not a speed-dial number. It is just a sequential value that is 

not associated with any phone number.
