SIP Phone Configuration Guide

1 Overview
The purpose of this configuration guide is to provide a basic overview of the SIP phones, allowing IT &
Telco technical experienced installers to proceed with provisioning of the phone and register to an IP
PBX. The intended audience for this document is Customer Service and Technical Installation
Personnel involved in the installation and maintenance of SIP phones. For bulk provisioning, please
refer to the Administration Guide for Hotel SIP Phone Admin Tool.
All SIP phones require proper configuration before use. Each SIP phone is equipped with a web
portal user interface for easy configuration and administration.
Inter-Op Partners
These SIP phones have successfully passed certification with PBX manufactures such as Alcatel,
Avaya, Broadcloud, Broadworks, Mitel, NEC, PhonesSuite and Siemens. For specific details of the
system, please contact your PBX service provider.
2 Before Configuration
All SIP phones must be setup & wired correctly before configuration. Please read the model specific
quick setup guide for setup & wiring instructions shipped with the phones.

SIP Phone Configuration Guide

3 Configure via Web Portal
Configure all SIP phones via web portal menus.
3.1 Configuration Process
3.1.1 Step 1: Obtain IP Address
To obtain auto IP address
By default, the phones automatically obtain IP address through DHCP server. You may use a DHCP
lease viewer to find out the IP address assigned by matching the MAC address on the back of the
phone with the search results displayed.
To discover IP address using the phone IP address read back
HD100
•Use the keypad to press and hold [VOL+] for more than 5 seconds, and then press [VOL-] [VOL+]
[VOL-] [VOL+] [VOL-] [BS1] [BS2] [BS3] in sequence.
HD101
•Press on its handset's keypad [TALK] [*] [*] [*] [*] [1] [2] in sequence.
HD350W & HD351W
•Press on its keypad [*] [4] [7] [1] [2] [3] [3] [#] in sequence.

3.1.2 Step 2: Access Web Portal
The SIP phone embedded web serverresponds to HTTPS request. Embedded HTML pages allow user
to configure the SIP phone via a web browser such as Microsoft’s IE (version 6.0 or later) or Mozilla
Firefox (version 4.0.1 or later).
Note: If you attempt to access the phones web interface and only end up with an empty / blank page,
you most probably tried to use HTTP instead of HTTPS. Please try again with https://
To access the web portal menu via Ethernet:
1. Connect the computer to the same network as the phone.
•The web enabled computer has tobe connected to the same sub-networkas theSIP phone.
This can easily be done by connecting the computer to the same hub/ switch that the SIP
phone is connected to.
2. Make sure the SIP phone is properly installed.
3. Open a web browser on your computer.
4. Enter https:// followed by the IP address of the SIP phone in the address bar of the browser.
•When the SIP phone is properly connected to a DHCP server, you can use the distributed
IP address of the SIP phone. The address is in the format: XXX.XXX.XXX.XXX, where XXX
represents a number from 0-255. You need this number to access the web portal menu.
•Please note most web browsers will report the website / the phone web user interface as
unsecure / not private or not trustworthy. This is due the nature of the phone built-in device
certificate which comes from a (for your browser) unknown / untrusted source (the Snom
Technology Root Authority). Beside that the CN, common name of the device certificate
cannot be identical to the IP address used to access the web interface. Due to the
production procedure the device certificate CN will correspond the specific LAN MAC
address of the phone. So, from the browsers perspective it will remain looking suspicious /
invalid, even you manage to import the Snom Technology Root Authority as a trusted
source into your browser / PC. This is common per design for embedded devices, like SIP
phones and you need to use an exception, confirming to your browser that you like to
connect despite the warning. If this exception is not offered in your browser, your browser
is most likely managed this way by your corporate IT / security team, and you need to
request this option from them.
5. When the login page appears, enter the administrator’s username and password to access the
web portal menu.
•The default username is admin and the default password is admin.
On the Web Portal, there is a navigation bar at the top and the respective submenus on the left.
Navigation bar topics:
•STATUS
•SYSTEM
•NETWORK
•SERVICING

The handset status page shows the name and the registration status of all the registered cordless
handsets. The page lists the maximum of four handsets, even if fewer handsets are registered. If you
have not given the handsets unique names, their default names of HANDSET will appear.
3.1.4 Step 4: Configure Web Portal Pages
3.1.5 Step 5: Reboot Phone System
A phone system reboot, after changing configuration of the following settings, is required in order to
apply the new settings:
•Network Configuration
•Network Security
•Static IP Mapping
•DECT
•Inter-Op Configuration
After saving the settings, click Reboot to perform phone system reboot.
3.2 Configure System Pages
3.2.1 SIP Account Management
On the SIP Account Management page, you can configure each account you have ordered from your
service provider or configured in your SIP-PBX. The SIP Account settings are also available as
parameters in the configuration file. See Section 6.6.1 SIP Account Settings ("sip_account" Module).

Section 3.2.1.2 Dial Plan.
Call Restriction Dial plan
To restrict users from dialing out numbers through dial plan matching
on a per-account basis.
Inter Digit Timeout (sec)
Set how long the HD10X waits after any "P" (pause) in the dial string
or in the dial plan.
Line Type
Select the line type to Private or Shared.
A private line will be accessible only at the HD10X you are
configuring. Shared lines can be assigned to more than one HD10X.
For more information about using shared lines, see HD10X User
Guide.
DTMF method
Select the default DTMF transmission method. You may need to
adjust this if call quality problems are triggering unwanted DTMF
tones or you have problems sending DTMF tones in general.
Unregister after reboot
Enable the phone to unregister the account(s) after rebooting - before
the account(s) register again as the phone starts up. If other phones
that share the same account(s) unregister unexpectedly in tandem
with the rebooting HD10X, disable this setting.
3.2.1.2 Dial Plan
The dial plan consists of a series of dialing rules, or strings, that determine whether what the user has
dialed is valid and when the HD10X should dial the number.
Dialing rules must consist of the elements defined in the table below.
Element
Description

SIP Phone Configuration Guide
- 13 -
x
Any dial pad key from 0 to 9, including # and *.
[0-9]
Any two numbers separated by a hyphen, where the second number is greater than the
first. All numbers within the range or valid, excluding # and *.
x+
An unlimited series of digits.
,
This represents the playing of a secondary dial tone after the user enters the digit(s)
specified or dials an external call prefix before the comma. For instance, "9,xxxxxxx"
means the secondary dial tone is played after the user dials 9 until any new digit is
entered. "9,3xxxxxx" means only when the digit 3 is hit would the secondary dial tone
stop playing.
PX
This represents a pause of a defined time; X is the pause duration in seconds. For
instance, "P3" would represent pause duration of 3 seconds. When "P" only is used, the
pause time is the same as the Inter Digit Timeout (see Section 3.2.1 SIP Account
Management).
(0:9)
This is a substitution rule where the first number is replaced by the second. For example,
"(4:723)xxxx" would replace "46789" with "723-6789". If the substituted number (the first
number) is empty, the second number is added to the number dialed. For example, in
"(:1)xxxxxxxxxx", the digit 1 is appended to any 10-digit number dialed.
|
This separator is used to indicate the start of a new pattern. Can be used to add multiple
dialing rules to one pattern edit box.
A sample dial plan appears below.
