Parameter Description
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.
Web: RTP Base UDP Port
EMS: Base UDP Port
[BaseUDPport]
Defines the lower boundary of the UDP port used for RTP,
RTCP (RTP port + 1) and T.38 (RTP port + 2). For example,
if the Base UDP Port is set to 6000, then one channel may
use the ports RTP 6000, RTCP 6001, and T.38 6002, while
another channel may use RTP 6010, RTCP 6011, and T.38
6012, and so on.
The range of possible UDP ports is 6,000 to 64,000. The
default base UDP port is 6000.
Once this parameter is configured, the UDP port range
(lower to upper boundary) is calculated as follows:

MP-112/MP-114: BaseUDPport to (BaseU
3*10)

MP-118: BaseUDPport to (BaseU 7*10)

MP-124: BaseUDPport to (BaseU 23*10)
Notes:

For this parameter to take effect, a device reset is
required.

The UDP ports are allocated randomly to channels.

If RTP Base UDP Port is not a factor of 10, the following
message is generated: 'invalid local RTP port'.
EMS: No Op Enable
[NoOpEnable]
Enables the transmission of RTP or T.38 No-Op packets.

[0] = Disable (default)

[1] = Enable
This mechanism ensures that the NAT binding remains
open during RTP or T.38 silence periods.
EMS: No Op Interval Defines the time interval in which RTP or T.38 No-Op
packets are sent in the case of silence (no RTP/T.38 traffic)
