Phone Setting
The RG230 allows the timings for certain events on the VoIP phone ports to be
precisely configured. For example, you can specify how long a phone will ring and
how long a dial tone is heard on a phone.
The RG230 also enables the line delay to be specified for each phone so that the
caller’s voice echo is cancelled.

Answer Timeout – The time after which a no answer message is sent to the caller.
(Range: 0-65535 seconds; Default: 180 seconds)
Release Timeout – The time after which a call is terminated when a phone is hung
up. (Range: 0-65535 seconds; Default: 4 seconds)
Dial Tone Timeout – The length of time a dial tone is heard on a connected phone.
(Range: 0-65535 seconds; Default: 16 seconds)
Inter Digit Timeout – The maximum time delay allowed between each dialed digit.
When the time is exceeded, a call is made using the dialed digits.
(Range: 0-65535 seconds; Default: 2 seconds)
Attended Transfer Timeout – The time after which a held call that is being
transferred is terminated. (Range: 0-65535 seconds; Default: 32 seconds)
Note: You can hold a call by pressing the “Flash,” “Flash Hook,” or “Hold” button on
the phone
, then dial a transfer number.
Line Echo Cancellation – Sets the delay time for voice echo cancellation. A voice
echo can be created on some two-wire phone loops, which becomes increasingly
louder and annoying when there is a long delay. If voice echo is a problem during a
call, you can adjust this parameter to try and reduce or remove it. (Options: 0, 8, 16,
24, 32, 36 milliseconds; Default: 0 milliseconds)
