LABEL DESCRIPTION
PSTN Line Pre-fix
Number
Enter 1 - 7 telephone keys (0 - 9, #, *) you dial before you dial the phone number,
if you want to make a regular 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. It is not recommended to use the # key, however, because it is also
used in Immediate Dial. (See VoIP > Phone > Common.)
Relay to PSTN
Line
Enter phone numbers (for regular calls, not VoIP calls) that you want to dial
without the prefix number. For example, you should enter emergency numbers.
The number (1 - 9) is not a speed-dial number. It is just a sequential value that is
not associated with any phone number.
