Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
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.
'RFC 2833 RX Payload Type'
telephony-events-payload-
type-rx
[RFC2833RxPayloadType]
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.
[EnableDetectRemoteMACChange] 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.
'Forward Invalid RTP Packets'
[RTPFWInvalidPacketHandling]
Defines the device's handling of invalid RTP and
RTCP packets.
■ [0] Forward Packets = Forwards the invalid
packets as is.
■ [1] Forward Packets and Issue Warnings =
(Default) Forwards the invalid packets and issues
warnings (sent to the Syslog) to notify of the
invalid packets.
■ [2] Drop Packets and Issue Warnings = Drops
the invalid packets and issues warnings to notify
of the invalid packets.
