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.

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.
The
General Settings
page consists of a manipulation radio
buttons group to select the mode of the NAT Traversal usage for
the SIP traffic (any incoming and outgoing SIP messages from
and to the Quadro will be routed through the NAT PC).
•
Automatic
– with this selection, system will analyze the
Quadro’s WAN IP address and if it is in the IP range
specified for local networks (according to RFC), the SIP
traffic will be routed through NAT. Otherwise, if Quadro’s
WAN IP address is outside the specified IP range, no SIP
traffic will be routed through NAT server.
•
Force
– with this selection, all the SIP traffic will be routed
through the NAT server.
•
Disable
– with this selection, no SIP traffic will be routed
through the NAT server.

The
SIP Parameters
page is used to configure NAT specific
settings for SIP and offers two independent groups of settings:
UDP Parameters
:
Manipulation radio buttons allow you to select the type of
connection over NAT:
Selecting
Use STUN
will switch to automatic discovery of
Mapped settings for the SIP UDP traffic over NAT. STUN
settings are configured on the STUN parameters page (see
below).
Selecting
Use Manual NAT Traversal
allows you to manually
define the mapped settings for the SIP UDP traffic over NAT:
Mapped Hos
t requires the IP address of the mapped host for
SIP UDP traffic over NAT.
Mapped Port
requires the port number on the mapped host
for the SIP UDP traffic over NAT.
TCP Parameters:
Mapped Hos
t requires the IP address of the mapped host for
SIP TCP traffic over NAT.
Mapped Port
requires the port number on the mapped host
