Version 5.8 357 September 2009
SIP User's Manual 6. Configuration Parameters Reference
Parameter Description
[EnableDetectRemoteMACChange]
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] = The device uses the received GARP packets to
change the MAC address of the transmitted RTP
packets (default).
[3] = Options 1 and 2 are used.
Note: For this parameter to take effect, a device reset is
required.
Web: Remote RTP Base UDP Port
EMS: Remote Base UDP Port
[RemoteBaseUDPPort]
Determines the lower boundary of UDP ports used for RTP,
RTCP and T.38 by a remote device. If this parameter is set
to a non-zero value, ThroughPacket™ (RTP multiplexing) is
enabled. The device uses this parameter (and
BaseUDPPort) to identify and distribute the payloads from
the received multiplexed IP packet to the relevant channels.
The valid range is the range of possible UDP ports: 6,000
to 64,000.
The default value is 0 (i.e., RTP multiplexing is disabled).
For detailed information on RTP multiplexing, refer to RTP
Multiplexing (ThroughPacket) on page 414.
Notes:
The value of this parameter on the local device must
equal the value of BaseUDPPort on the remote device.
To enable RTP multiplexing, the parameters
L1L1ComplexTxUDPPort and L1L1ComplexRxUDPPort
must be set to a non-zero value.
When VLANs are implemented, RTP multiplexing is not
supported.
RTP Multiplexing Local UDP Port
[L1L1ComplexTxUDPPort]
Determines the local UDP port used for outgoing
multiplexed RTP packets (applies to RTP multiplexing).
The valid range is the range of possible UDP ports: 6,000
to 64,000.
The default value is 0 (i.e., RTP multiplexing is disabled).
Note: For this parameter to take effect, a device reset is
required.
