The Packetization Interval is the time interval between two RTP
packets of the same stream. If the interval is increased, the
overhead is decreased but the voice quality may deteriorate as a
result. If the interval is decreased, the network load is increased
and the delay is reduced.
Silence Suppression disables RTP packet transmission in case
of no voice activity. This feature helps to avoid extra traffic if the
RTP stream contains no voice activity. It is activated after two
seconds of silence and restarted immediately if any audio
appears.
The G.726 Standard radio buttons are used to select between
packaging the G.726 codewords into octets. If you experience
problems with the G.726 voice quality when one of these
packaging is selected, try a different one.
• If Use ITU_T specification is selected, the ITU I.366.2
(“AAL2 type 2 service specific convergence sublayer for
narrow-band services”) type packaging of codewords is used,
where packing code words into octets is starting from the
most significant rather than the least significant digit in the
octet.
• If Use IETF RFC is selected, the IETF RFC (“RTP Profile for
Audio and Video Conferences with Minimal Control”) type
packaging of codewords is used, where packing code words
is starting from the least significant position in the octet.

RTP/RTCP Port Range:
• Min - minimal port has to be higher than 1024 and lower than the maximal port range. Only even numbers are allowed.
• Max - maximal port has to be lower than 65536 and higher than the minimal port range. Only odd numbers are allowed.
Since the specified maximum port has to be higher than the minimum port, the error message “Min port number should be less than max port
number” will appear if this condition is not met.
The port range must consist of digits only, otherwise the error “Incorrect Port Range: only Integer
values allowed” will appear. The difference between Max and Min RTP ports should be 100 ports or less (according to the system’s capabilities)
otherwise the corresponding warning appears. RTP/RTCP Port ranges cannot include the defined SIP UDP ports (see SIP Settings
) otherwise an
error message will appear.
Telephone Event Draft Support enables telephony events transmission according to the draft-ietf-avt-rfc2833bis-04. The checkbox needs to be
toggled if the SIP destination party phone or IVR has problems recognizing DTMFs generated by the Quadro.
Enable RTCP Support enables Real Time Control Protocol support and allows for the RTCP packets transmission. RTCP protocol is used for
monitoring the RTP streams and changing RTP characteristics depending on Network conditions.
The RTP Settings – Edit Entry page offers a drop down list and a
checkbox.
Packetization Interval contains possible values (in milliseconds)
to be configured for the selected codec.
The Enable Silence Suppression checkbox selection enables
voice activity detection for the selected codec.

To Edit Codec Parameters
1. Select the codec from the Codecs Table that is to be edited.
2. Press the Edit button on the RTP Settings page. The Edit Entry page will appear in the browser window.
3. Change values in Packetization Interval and/or enable/disable Silence Suppression.
4. To save the codec settings press Save, or to keep the initial data click Back.
NAT Traversal Settings
The NAT Traversal Settings page is divided into separate pages used to configure General NAT settings, SIP NAT parameters, RTP and STUN
parameters for NAT and a page where the NAT Exclusion table may be filled.
