Layer 3 QoS
This field defines the layer 3 QoS parameter which can be the value
used for IP Precedence or Diff-Serv or MPLS. Default value is 48.
Layer 2 QoS
This contains the value used for layer 2 VLAN tag. Default setting is
blank.
No Key Entry
Timeout
Default is 4 seconds.
Use # as
Send Key
This parameter allows users to configure the “#” key to be used as the
“Send” (or “Dial”) key. If set to “Yes”, pressing this key will
immediately trigger the sending of dialed string collected so far. In this
case, this key is essentially equivalent to the “(Re)Dial” key. If set to
“No”, this “#” key will then be included as part of the dial string to be
sent out.
Local RTP port
This parameter defines the local RTP-RTCP port pair the GXP-2000
will listen and transmit. It is the base RTP port for channel 0. When
configured, channel 0 will use this port _value for RTP and the
port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP
and port_value+3 for its RTCP. The default value is 5004.
Use Random
Port
This parameter, when set to Yes, will force random generation of both
the local SIP and RTP ports. This is usually necessary when multiple
GXP-2000s are behind the same NAT.
Keep-alive
interval
This parameter specifies how often the GXP-2000 sends a blank UDP
packet to the SIP server in order to keep the “hole” on the NAT open.
Default is 20 seconds.
Use NAT IP
NAT IP address used in SIP/SDP message. Default is blank.
STUN Server
IP address or Domain name of the STUN server.
Firmware
Upgrade and
provisioning
This radio button will enable GXP-2000 to download firmware or
configuration file through either TFTP or HTTP.
