model, some of these Vocoders may not be provided in standard release.
Users can configure Vocoders in a preference list that will be included with the
same preference order in SDP message. The first Vocoder in this list can be
entered by choosing the appropriate option in "Choice 1". Similarly, the last
Vocoder in this list can be entered by choosing the appropriate option in
"Choice 6".
This defines the encoding rate for G723 vocoder. By default, 6.3kbps rate is
chosen.
This sets the iLBC frame size in 20ms or 30ms
between 96 and 127.
"Yes", when a silence is detected, small quantity of VAD packets (instead of
audio packets) will be sent during the period of no talking. If set to "No", this
feature is disabled.
This parameter controls whether the phone will attempt to send an early
INVITE each time a key is pressed when a user dials a number. If set to "Yes",
an INVITE is sent using the dial-number collected thus far; Otherwise, no
INVITE is sent until the "(Re-)Dial" button is pressed or after about 5 seconds
have elapsed if the user forgets to press the "(Re-)Dial" button.
The "Yes" option should be used ONLY if there is a SIP proxy configured and
the proxy server supports 484 Incomplete Address response. Otherwise, the call
will most likely be rejected by the proxy (with a 404 Not Found error).
Please note that this feature is NOT designed to work with and should NOT be
enabled for direct IP-to-IP calling.
