5.3 Configuration through a Central Server 
Grandstream HandyTone ATAs can be automatically configured via a central 
provisioning system called Grandstream Automated Provisioning System (GAPS). 
With GAPS, a service provider or an enterprise with large deployment of 
HandyTone ATAs can easily manage the configuration and service provisioning of 
individual devices remotely and automatically via a central server. GAPS uses 
enhanced (NAT friendly) tftp and other communication protocols to communicate 
with each individual HandyTone ATA even if the HandyTone ATA is behind a 
NAT. 
GAPS must be used to support automated configuration of an HandyTone ATA. To 
enable this feature on the HandyTone ATA, the user just needs to enter the IP 
address of GAPS server in the tftp server field of the configuration screen. Then 
power cycle the HandyTone ATA. 
For details on how GAPS works, please refer to the documentation of GAPS 
product. 
6. Software Upgrade 
6.1 Upgrade with TFTP 
To upgrade software, HandyTone ATAs can be configured with a TFTP server 
where the new code image is located. The TFTP upgrade can work in either static IP 
or DHCP mode using private or public IP address. It is recommended that the TFTP 
server must have either public IP address or be on the same LAN with the 
HandyTone ATA. 
There are 2 ways to set up the TFTP server to upgrade the firmware, namely through 
voice menu prompt or via the HandyTone ATA’s Web configuration interface. To 
configure the TFTP server via voice prompt, follow section 4.1 with option 06, once 
set up the tftp ip address, power cycle the ATA, the firmware will be fetched once 
the ATA boot up.
