Table 148 Voice Features
Call Fallback Call fallback allows you to set the ZyXEL Device to automatically use the PSTN
connection for outgoing calls if the SIP account is not working, or to use the SIP
account for outgoing calls if the PSTN port is unplugged or not working.
Call Park and
Pickup
Call park and pickup lets you put a call on hold (park) and then continue the call
(pickup). You can continue the call on the same phone, or another phone
connected to the ZyXEL Device. The caller must still pay while the call is
parked.
When you park the call, you enter a number of your choice (up to eight digits),
which you must enter again when you pick up the call. If you do not enter the
correct number, you cannot pickup the call. This means that only someone who
knows the number you have chosen can pick up the call.
You can have more than one call on hold at the same time, but you must give
each call a different number.
Country Code Phone standards and settings differ from one country to another, so the settings
on your ZyXEL Device must be configured to match those of the country you
are in. The country code feature allows you to do this by selecting the country
from a list rather than changing each setting manually. Configure the country
code feature when you move the ZyXEL Device from one country to another.
Auto Dial You can set the ZyXEL Device to automatically dial a specified number
immediately whenever you lift a phone off the hook. Use the Web Configurator
to set the specified number. Use the command line interpreter to have the
ZyXEL Device wait a specified length of time before dialing the number.
Music on hold This feature allows you to put a call on hold and have the other person hear a
piece of audio (music, speech, etc.) you previously recorded.
Internal call When you have phones attached to both of the ZyXEL Device’s phone ports,
you can dial “####” to place a call to the phone(s) connected to the other port.
Firmware update
enable / disable
If your service provider uses this feature, you hear a recorded message when
you pick up the phone when new firmware is available for your ZyXEL Device.
Enter *99# in your phone’s keypad to have the ZyXEL Device upgrade the
firmware, or enter #99# to not upgrade. If your service provider gave you
different numbers to use, enter them instead. If you enter the code to not
upgrade, you can make a call as normal. You will hear the recording again each
time you pick up the phone, until you upgrade.
