(Click the scrollbar to view the remaining options.)
The options are:
DB read from backup memory, if reset – If set to 'Enable' this will reload customer data
•
from the flash memory when the card is reset or the router is switched off and on. If this is
set to 'Disable', only the default settings will be loaded.
Multi Frame Count – This option sets how many frames of encoded speech a re loaded into
•
an IP packet. When using the G723.1 Audio Codec (see below) the most efficient option is 3
frames; when using the G729A Audio Codec, this should be set to 9.
Echo Cancellation – This cancels locally generated echoes caused by analogue interfaces.
•
The preferred setting is 'Enable'.
Ring Back Tone Support – This option allows the VIP to generate Ring Back Tone (RBT) to
•
incoming callers over the VoIP connection. To reduce the amount of bandwidth used for VoIP,
this option is set to 'Disable'. If the caller wants to receive RBT, it must be generated locally.
Silence Suppression – This option is also used to conserve the bandwidth used for VoIP
•
calls. This prevents the sending of silence to the remote party. This will normally be set to
'Enable'.
Audio Codec – There are two options available on the VIP: G723.1 (6.3kbps) and G729A
•
(8kbps). However, the VIP will auto-negotiate which Codec is compatible with the call being
made and what the remote party can use.
VoIP Gateway ID – This option sends the digits inserted into this field as a calling line
•
identification (CLI) to the called party.
DTMF Generation Type(#) – Inband/Signalling/DCS-VIP.
•
Gatekeeper Type(#) – Samsung Gatekeeper/Other Gatekeeper.
•
Billing Type(#) – Samsung Billing Type/Standard Billing Type.
•
Note: Options marked (#) cannot be changed while the VoIP card is in use.
