Grandstream Networks 200

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.
