Configuration via Web Browser
The GRP261X embedded Web server responds to HTTP/HTTPS GET/POST requests. Embedded HTML
pages allow a user to configure the IP phone through a Web browser such as Google Chrome, Mozilla
Firefox and Microsoft’s IE. To access the Web GUI:
1. Connect the computer to the same network as the phone.
2. Make sure the phone is turned on and shows its IP address. You may check the IP address by
pressing and holding UP arrow button for 3 seconds when phone is at idle state.
3. Open a Web browser on your computer.
4. Enter the phone’s IP address in the address bar of the browser.
5. Enter the administrator’s login and password to access the Web Configuration Menu.
Notes:
The computer must be connected to the same sub-network as the phone. This can be easily done by
connecting the computer to the same hub or switch as the phone connected to. In absence of a
hub/switch (or free ports on the hub/switch), please connect the computer directly to the PC port on the
back of the phone;
If the phone is properly connected to a working Internet connection, the IP address of the phone will
display in MENUStatusNetwork Status. This address has the format: xxx.xxx.xxx.xxx, where xxx
stands for a number from 0-255. Users will need this number to access the Web GUI. For example, if
the phone has IP address 192.168.40.154, please enter “http://192.168.40.154” in the address bar of
the browser;
There are two default passwords for the login page:
Only Status and Basic
Settings
Random password available
on the sticker at the back of
the unit.
When changing any settings, always SUBMIT them by pressing the “Save” or “Save and Apply” button
on the bottom of the page. If the change is saved only but not applied, after making all the changes,
click on the “APPLY” button on top of the page to submit. After submitting the changes in all the Web
GUI pages, reboot the phone to have the changes take effect if necessary (All the options under
“Accounts” page and “Phonebook” page do not require reboot. Most of the options under “Settings”
page do not require reboot).

until the "Apply" button on the top of web GUI page is clicked. Or, users could directly press "Save and
Apply" button. We recommend rebooting or powering cycle the phone after applying all the changes.

If the user wishes to locate the server by DNS SRV, the user may select
“SRV” or “NATPTR/SRV”.
If “Use Configured IP” is selected, please fill in the three fields below:
Primary IP
Backup IP 1
Backup IP 2
If SIP server is configured as domain name, phone will not send DNS query,
but use “Primary IP” or “Backup IP x” to send SIP message if at least one of
them are not empty.
Phone will try to use “Primary IP” first. After 3 tries without any response, it
will switch to “Backup IP x”, and then it will switch back to “Primary IP” after
3 re-tries.
If SIP server is already an IP address, phone will use it directly even “User
Configured IP” is selected.
The option will decide which IP is going to be used in sending SIP packets
after IPs for SIP server host are resolved with DNS SRV.
Default
If the option is set with “default”, it will again try to send register messages to
one IP at a time, and the process repeats.
Saved one until DNS TTL
If the option is set with “Saved one until DNS TTL”, it will send register
messages to the previously registered IP first. If no response, it will try to
send one at a time for each IP. This behavior lasts if DNS TTL (time-to-live)
is up.
Saved one until no responses
If the option is set with “Saved one until no responses”, it will send register
messages to the previously registered IP first, but this behavior will persist
until the registered server does not respond.

X – digits from 0-9, and letters from a-z, A-Z.

GRP261x Administration Guide
Version 1.0.5.45
a) xx+ - at least 2-digit numbers
b) xx — only 2-digit numbers
c) ^ — exclude
d) [3-5] — any digit of 3, 4, or 5
e) [147] — any digit of 1, 4, or 7
f) <2=011> - replace digit 2 with 011 when dialing
g) | — the OR operand
h) , - second dial tone. For example: {0,x+} will play second dial tone
after dialing 0 and all digits will be sent including 0
i) {X123} — match Z123, e123, 5123, …
j) Flag T when adding a “T” at the end of the dial plan, the phone will
wait for 3 seconds before dialing out. This gives users more flexibility
on their dial plan setup. E.g. with dial plan 1XXT, phone will wait for
3 seconds to let user dial more than just 3 digits if needed. Originally
the phone will dial out immediately after dialing the third digit.
k) Back slash “\” — can be used to escape specific letters. E.g. if
{ \p\a\r\k\+60 } dial plan is configured, park+60 should be able to
pass dial plan check. This also can be used to escape Mark and
User-unreserved characters.
Mark = “-“ / “_” / “.” / “!” / “~” / “*” / “’” / “(“ / “)”
User-unreserved = “&” / “=” / “+” / “$” / “,” / “;” / “?” / “/”
Example 1: {[369]11 | 1617xxxxxxx}
Allow 311, 611, and 911 or any 10 digit numbers with leading digits 1617;
Example 2: {^1900x+ | <=1617>xxxxxxx}
Block any number of leading digits 1900 or add prefix 1617 for any dialed 7
digit numbers;
Example 3: {1xxx[2-9]xxxxxx | <2=011>x+}
Allows any number with leading digit 1 followed by a 3-digit number, followed
by any number between 2 and 9, followed by any 7-digit number OR Allows
any length of numbers with leading digit 2, replacing the 2 with 011 when
dialed.
Example 4: If we set the dial plan with {\*123}, it should allow input *123
to pass dial plan check.
Example 5: If we set the dial plan with {\$123}, it should allow input $123
to pass dial plan check.
Example 6: If we set the dial plan with {12\_3}, it should allow input 12_3
to pass dial plan check.
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 }

GRP261x Administration Guide

Explanation of example rule (reading from left to right):
^1900x. — prevents dialing any number started with 1900;
<=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 — allows dialing special and emergency numbers 311, 411,
611 and 911.
Note: In some cases, where the user wishes to dial strings such as *123 to
activate voice mail or other applications provided by their service provider,
the * should be predefined inside the dial plan feature.
An example dial plan will be: {*x+} which allows the user to dial * followed by
any length of numbers.
