Table 76 Voice Features Call Return With call return, you can place a call to the last number that called you (either answered or missed). The last incoming call can be through either SIP or PSTN. 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. Phone config The phone config table allows you to customize the phone keypad combinations you use to access certain features on the ZyXEL Device, such as call waiting, call return, and call forward. The phone config table is configurable in command interpreter mode. Call waiting This feature allows you to hear an alert when you are already using the phone and another person calls you. You can then either reject the new incoming call, put your current call on hold and receive the new incoming call, or end the current call and receive the new incoming call. Call forwarding With this feature, you can set the forward calls to a specified number, either unconditionally (always), when your number is busy, or when you do not answer. You can also forward incoming calls from one specified number to another. Caller ID The ZyXEL Device supports caller ID, which allows you to see the originating number of an incoming call (on a phone with a suitable display). Dynamic Jitter Buffer The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic. This helps ensure good voice quality for your conversations. Multiple Voice Channels Your device can simultaneously handle multiple voice channels (telephone calls). Additionally you can answer an incoming phone call on a VoIP account, even while someone else is using the account for a phone call. Voice Activity Voice Activity Detection (VAD) reduces the bandwidth that a call uses Detection/Silence by not transmitting when you are not speaking. Suppression Comfort Noise Generation Your device generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection). 248 P-2601HN(L)-F1 Series User's Guide

Table 76
Voice Features
Call Return
With call return, you can place a call to the last number that called
you (either answered or missed). The last incoming call can be
through either SIP or PSTN.
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.
Phone config
The phone config table allows you to customize the phone keypad
combinations you use to access certain features on the ZyXEL Device,
such as call waiting, call return, and call forward. The phone config
table is configurable in command interpreter mode.
Call waiting
This feature allows you to hear an alert when you are already using
the phone and another person calls you. You can then either reject
the new incoming call, put your current call on hold and receive the
new incoming call, or end the current call and receive the new
incoming call.
Call forwarding
With this feature, you can set the forward calls to a specified number,
either unconditionally (always), when your number is busy, or when
you do not answer. You can also forward incoming calls from one
specified number to another.
Caller ID
The ZyXEL Device supports caller ID, which allows you to see the
originating number of an incoming call (on a phone with a suitable
display).
Dynamic Jitter
Buffer
The built-in adaptive buffer helps to smooth out the variations in
delay (jitter) for voice traffic. This helps ensure good voice quality for
your conversations.
Multiple Voice
Channels
Your device can simultaneously handle multiple voice channels
(telephone calls). Additionally you can answer an incoming phone call
on a VoIP account, even while someone else is using the account for a
phone call.
Voice Activity
Detection/Silence
Suppression
Voice Activity Detection (VAD) reduces the bandwidth that a call uses
by not transmitting when you are not speaking.
Comfort Noise
Generation
Your device generates background noise to fill moments of silence
when the other device in a call stops transmitting because the other
party is not speaking (as total silence could easily be mistaken for a
lost connection).
