GXV-3000 User Manual Grandstream Networks, Inc.
- 32 -
Local RTP
port
This parameter defines the local RTP-RTCP port pair the GXV-3000 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 GXV-3000s are behind the
same NAT.
Keep-alive
interval
This parameter specifies how often the GXV-3000 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 GXV-3000 to download firmware or configuration file
through either HTTP or local TFTP server. This is mutual exclusive choice.
Via TFTP
Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or
not blank, the GXV-3000 will attempt to retrieve new configuration file or new code
image from the specified TFTP server at boot time. It will make up to 3 attempts
b
efore timeout and then it will start the boot process using the existing code image in
the Flash memory. If a TFTP server is configured and a new code image is retrieved,
the new downloaded image will be verified and then saved into the Flash memory.
Note: It is strongly recommended that user upgrade firmware locally in LAN
environment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade
process (especially the power supply) as this will damage the device.
Via HTTP
Server
The URL for the HTTP server used for firmware upgrade and configuration via
HTTP. For example,
http://provisioning.mycompany.com:6688/Grandstream/1.0.0.14
Here “:6688” is the specific TCP port that the HTTP server is listening at, it can be
omitted if using default port 80.
Note: If Auto Upgrade is set to No, GXV-3000 will only do HTTP download once
at boot up.
Automatic
Upgrade
Default is Yes. Choose Yes to enable automatic HTTP upgrade and provisioning.
In “Check for upgrade every” field, enter the number of minutes to enable the phone
to check the HTTP server for firmware upgrade or configuration changes in the
defined period of time.
When set to No, the phone will only do HTTP upgrade and configuration check once
at boot up. Used by ITSP. End user should NOT touch these parameters.
DTMF
Payload Type
This parameter sets the payload type for DTMF using RFC2833.
