Parameter Description
Web/EMS: RFC 2833 RX Payload
Type
[RFC2833RxPayloadType]
Defines the Rx RFC 2833 DTMF relay dynamic payload
type.
The valid range is 96 to 99, and 106 to 127. The default is
96. The 100, 102 to 105 range is allocated for proprietary
usage.
Notes:

Certain vendors (e.g., Cisco) use payload type 101 for
RFC 2833.

When RFC 2833 payload type negotiation is used (i.e.,
the parameter TxDTMFOption 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.
Notes:

For this 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 this parameter to 0 or 2.
