Local RTP
port This parameter defines the local RTP-RTCP port pair the BudgeTone 200
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
BudgeTone 200s are behind the same NAT.
Keep-alive
interval This parameter specifies how often the BudgeTone 200 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 BudgeTone 200 to download firmware or
configuration file through either TFTP or HTTP.
Via TFTP
Server This is the IP address of the configured TFTP server. If selected and it is
non-zero or not blank, the BudgeTone 200 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 before 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: Please do NOT interrupt the TFTP upgrade process (especially the
power supply) as this will damage the device. Depending on the network
environment this process can take up to 15 or 20 minutes.
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/1.0.5.16
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, BudgeTone 200 will only do HTTP
download once at boot up.
Allow DHCP
Option 66 to
override
server
DHCP Option 66 is used to identify a TFTP server when the 'sname' field in
the DHCP header has been used for DHCP options. If you choose yes,
BT200 will use the TFTP server resolved from DHCP, instead of the one you
specified in the "TFTP Server" option above.
