HandyTone-488 User Manual

Grandstream Networks, Inc.

Keep-alive

This parameter specifies how often the HandyTone ATA sends a blank

interval

UDP packet to the SIP server in order to keep the “hole” on the NAT

 

open.

 

Use NAT IP:

NAT IP address used in SIP/SDP message. Default is blank.

Proxy-Require

SIP Extension to notify SIP server that the unit is behind the

 

NAT/Firewall.

 

TFTP Upgrade

This is the IP address of the configured TFTP server. If it is non-zero or

Server

not blank, the HandyTone ATA 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.

 

HTTP Upgrade

The URL for the HTTP server used for firmware upgrade and

Server

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: Auto Upgrade has to be set to Yes to enable HTTP upgrade.

Auto Upgrade

Choose Yes to enable HTTP upgrade and provisioning.

 

In “Check for new firmware every” field, enter the number of days to

Offhook

This parameter allows users to configure a User ID or extension number

Auto-Dial

to be automatically dialed upon offhook. Please note that only the user

 

part of a SIP address needs to be entered here. The HandyTone ATA

 

will automatically append the “@” and the host portion of the

 

corresponding SIP address.

 

Send Flash Event

This parameter allows users to control whether to send an SIP NOTIFY

 

message indicating the Flash event, or just to switch to the voice

 

channel when users press the Flash key.
