User's Manual
Defines the Tx RFC 2833 DTMF relay dynamic payload type
for outbound calls.
The valid range is 96 to 127. The default is 96.
Note: When RFC 2833 payload type negotiation is used (i.e.,
the parameter FirstTxDTMFOption is set to 4), this payload
type is used for the received DTMF packets. If negotiation isn't
used, this payload type is used for receive and for transmit.
Defines the Rx RFC 2833 DTMF relay dynamic payload type
for inbound calls.
The valid range is 96 to 127. The default is 96.
Note: When RFC 2833 payload type negotiation is used (i.e.,
the parameter FirstTxDTMFOption is set to 4), this payload
type is used for the received DTMF packets. If negotiation isn't
used, this payload type is used for receive and for transmit.
Determines whether the device changes the RTP packets
according to the MAC address of received RTP packets and
according to Gratuitous Address Resolution Protocol (GARP)
messages.

[0] = Nothing is changed.

[1] = If the device receives RTP packets with a different
source MAC address (than the MAC address of the
transmitted RTP packets), then it sends RTP packets to
this MAC address and removes this IP entry from the
device's ARP cache table.

[2] = (Default) The device uses the received GARP packets
to change the MAC address of the transmitted RTP
packets.

[3] = Options 1 and 2 are used.
Note:

For the parameter to take effect, a device reset is required.

If the device is located in a network subnet which is
connected to other gateways using a router that uses
Virtual Router Redundancy Protocol (VRRP) for
redundancy, then set the parameter to 0 or 2.
Global parameter that defines the lower boundary of the UDP
port used for RTP, RTCP (RTP port + 1) and T.38 (RTP port +
2). For more information on configuring the UDP port range,
see ''Configuring RTP Base UDP Port'' on page 203.
The range of possible UDP ports is 6,000 to 64,000. The
default base UDP port is 6000.
Note: For the parameter to take effect, a device reset is
required.
Disables RTCP traffic when there is no RTP traffic. This
feature is useful, for example, to stop RTCP traffic that is
typically sent when calls are put on hold (by an INVITE with
'a=inactive' in the SDP).

[0] Active Always = (Default) RTCP is active even during
