Dial Plan Rules:
1. Accept Digits: 1,2,3,4,5,6,7,8,9,0 , *, #, A,a,B,b,C,c,D,d
2. Grammar: x - any digit from 0-9;
a. xx+ - at least 2 digits number;
b. xx – exactly 2 digits number;
c.
^ - exclude;
d. . – wildcard, matches one or more characters
e. [3-5] - any digit of 3, 4, or 5;
f.
[147] - any digit 1, 4, or 7;
g. <2=011> - replace digit 2 with 011 when dialing
h. < =1> - add a leading 1 to all numbers dialed, vice versa will remove a
1 from the number dialed
i.
| - or
Example 1: {[369]11 | 1617xxxxxxx} –
•
Allow 311, 611, 911, and any 10 digit numbers of leading digits 1617
Example 2: {^1900x+ | <=1617>xxxxxxx} –
•
Block any number with leading digits 1900 and add prefix 1617 for any
dialed 7 digit numbers
•
Example 3: {1xxx[2-9]xxxxxx | <2=011>x+} –
Allow any length of number with leading digit 2 and 10 digit-numbers of
leading digit 1 and leading exchange number between 2 and 9; If leading
digit is 2, replace leading digit 2 with 011 before dialing.
3. Default: Outgoing - {x+}
Example of a simple dial plan used in a Home/Office in the US:
{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 }
Explanation of example rule (reading from left to right):
• ^1900x. - prevents dialing any number started with 1900
HT801 Administration Guide
P a g e | 33
• <=1617>[2-9]xxxxxx
- allows dialing to local area code (617) numbers by dialing
7 numbers and 1617 area code will be added automatically
• 1[2-9]xx[2-9]xxxxxx
- allows dialing to any US/Canada Number with 11 digits
length
• 011[2-9]x. - allows international calls starting with 011
• [3469]11 - allow dialing special and emergency numbers 311, 411, 611 and 911
Note: In some cases, user wishes to dial strings such as *123 to activate voice mail or
other application provided by service provider. In this case * should be predefined inside

If you plan to keep the handy tone within a private network behind a firewall, we recommend using STUN
Server. The following three settings are useful in the STUN Server scenario:
1. STUN Server (under advanced settings webpage) enter a STUN server IP (or FQDN) that you may
have, or look up a free public STUN server on the internet and enter it on this field. If using public IP,
keep this field blank.
2. Use random SIP/RTP ports (under advanced settings webpage), this setting depends on your network
settings. Generally, if you have multiple IP devices under the same network, it should be set to Yes. If
using a public IP address, set this parameter to No.
3. NAT traversal (under the FXS web page) Set this to Yes when gateway is behind firewall on a private
network.

HT801 Administration Guide
P a g e | 42
Upgrading via Local Directory:
1. Download the firmware file from Grandstream web site;
2. Unzip it and copy the file in to a folder in your PC;
3. From the HT801 web interface (Advanced Settings page) you can browse your hard drive and
select the folder you previously saved the file (HT801fw.bin);
4. Click “Upload Firmware” and wait few minutes until the new program is loaded.
Note: Always check the status page to see that the program version has changed.
Upgrading via Local TFTP/(TTP Servers
For users that would like to use remote upgrading without a local TFTP/HTTP server, Grandstream offers
a NAT-friendly HTTP server. This enables users to download the latest software upgrades for their devices
via this server. Please refer to the webpage:
http://www.grandstream.com/support/firmware
Alternatively, users can download a free TFTP or HTTP server and conduct a local firmware upgrade. A
free window version TFTP server is available for download from:
http://www.solarwinds.com/products/freetools/free_tftp_server.aspx
http://tftpd32.jounin.net/.
Instructions for local firmware upgrade via TFTP:
1. Unzip the firmware files and put all of them in the root directory of the TFTP server.
2. Connect the PC running the TFTP server and the phone to the same LAN segment.
3. Launch the TFTP server and go to the File menu->Configure->Security to change the TFTP server's
default setting from "Receive Only" to "Transmit Only" for the firmware upgrade.
4. Start the TFTP server and configure the TFTP server in the phone’s web configuration interface.
5. Configure the Firmware Server Path to the IP address of the PC.
6. Save and Apply the changes and reboot the HT801.
End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use
Microsoft IIS web server.
Firmware and Configuration File Prefix and Postfix
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and
Postfix. This makes it the possible to store all of the firmware with different version in one single directory.
Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching
Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory.
In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the
device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.
HT801 Administration Guide
P a g e | 43
Managing Firmware and Configuration File Download
When “Automatic Upgrade” is set “Yes, every” the auto check will be done in the minute specified in this
field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the
devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to
“weekly on day (0-6)” the auto check will be done on the day specified in this field. This allows the device
periodically check if there are any new changes need to be taken on a scheduled time. By defining
different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration
File download in minutes to reduce the Firmware or Provisioning Server load at any given time.
Configuration File Download
Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File
(binary or XML) through TFTP or HTTP/HTTPS. The Config Server Path is the TFTP or HTTP/HTTPS
server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.
The Config Server Path can be the same or different from the Firmware Server Path.
A configuration parameter is associated with each particular field in the web configuration page. A
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric
numbers. i.e., P2 is associated with the "New Password" in the Web GUI->Maintenance->Web/SSH Access
page->Admin Password. For a detailed parameter list, please refer to the corresponding firmware release
configuration template.
When the HT801 boots up or reboots, it will send a request to download a file named "cfgxxxxxxxxxxxx”
followed by a configuration XML file named "cfgxxxxxxxxxxxx.xml", where "xxxxxxxxxxxx" is the MAC
address of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If the download of
"cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a generic cfg.xml file. The
configuration file name should be in lower case letters.
For more details on XML provisioning, please refer to:
