It is very important to provide a Group function for voice service within a company.
Customers can simultaneously call the same phone number. When the Vigor3300 gets a phone
call, which is configured in the first port of a group from Internet, it will ring all available
ports belonging to this group to provide voice service at the same time. It is easier for the
customer to remember just one phone number corresponding to the company. By enabling this
function, the 4- or 8-port VoIP will use the first enabled port phone setting on the table as their
phone number.
Up to 8 groups can be configured and assigned a specific phone line. Each phone line must be
unique and cannot be overlapped as shown below.

FAX Bypass Codec Rate - Select one option (20 or 40) to be
applied if FAX mode is configured as Bypass mode. The
stability for the faxing result of documents with codec rate
20ms is higher than 40ms. Yet, the bandwidth request for 40ms
is less than 20ms.
DTMF Mode -
InBand: Choose this one then the Vigor will send the DTMF
tone as audio directly when you press the keypad on the phone.
OutBand (RFC2833): Choose this one then the Vigor will
capture the keypad number you pressed and transform it to
digital form then send to the other side; the receiver will
generate the tone according to the digital form it receive. This
function is very useful when the network traffic congestion
occurs and it still can remain the accuracy of DTMF tone.
SIP INFO: Choose this one then the Vigor will capture the
DTMF tone and transfer it into SIP form. Then it will be sent to
