User Interfaces

Two ways to customize configurations of your SIP-T20P/SIP-T20 IP phone:

• The user Interface on the IP phone.
• The user Interface in a web browser on your PC.

The hardware components keypad and LCD screen constitute the phone user interface, which allows the user to execute all call operation tasks and basic configuration changes directly on the phone. In addition, each phone has a web user interface to access all configuration settings. In many cases, either the phone user interface and/or the web user interface interchangeably. However, in some cases, it is only possible to use one or the other interface to operate the phone and change settings.

Phone User Interface

You can customize your phone by pressing the MENU key to access the phone user interface. The Advanced option is only accessible to the administrator, and the default administrator password is "admin" (case-sensitive). For more information on customizing your phone with the available options from the phone user interface, refer to Customizing Your Phone on page 19.

Web User Interface

In addition to the phone user interface, you can also customize your phone via web user interface. In order to access the web user interface, you need to know the IP address of your new phone. To obtain the IP address, press the OK key on the phone when the phone is idle. Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of a web browser on your PC. The default administrator user name and password are both "admin" (case-sensitive).

The options you can use to customize the IP phone via phone user interface and/or via web user interface are listed in the following table:

Dial Plan

Dial plan is a string of characters that governs the way your SIP-T20P/SIP-T20 IP phone processes the inputs received from your phone keypad. The SIP-T20P/SIP-T20 IP phone supports the following dial plan features:

• Replace Rule
• Dial-now
• Area Code
• Block Out

The basic expression syntax you need to know:

.	The dot "." can be used as a placeholder or multiple placeholders for any character. Example: "12." would match "123", "1234", "12345", etc.
x	An "x" can be used as a placeholder for any character. Example: "12x" would match "121", "122", "123", etc.
[]	The square brackets "[]" can be used as a placeholder for a single character which matches any of a set of characters. Example: "91[5-7]1234" would match "9151234", "9161234", "9171234".
()	The parentheses "( ) "can be used to group together patterns, for instance, to logically combine two or more patterns. Example: "91([5-7])1(x)" would match "91511", "91618", "91715".
	The "" should be followed by the sequence number of a parenthesis. The "" plus the sequence number means the whole character or characters placed in the parenthesis. The number directs to the right parenthesis when there are more than one. Example:A replace rule configuration, Prefix: "001(xxx)45(xx)", Replace: "90011452". When you dial out "0012354599" on your phone, the IP phone will replace the number with "90012354599". "1" means 3 digits in the first parenthesis, that is, "235". "$2" means 2 digits in the second parenthesis, that is, "99".

Replace Rule

You can configure one or more replace rules (up to 100) to remove the specified string and replace it with another string. You can configure a pattern with wildcards (refer to the expression syntax in the table above), so that any string that matches the pattern will be replaced. This feature is convenient for you to dial out a long number. For example, a replace rule is configured as "Prefix: 1" and "Replace: 1234", when you try to dial out the number "1234", you just need to enter "1" on the phone and then press the Send soft key.

To add a replace rule via web user interface:

1. Click on Settings->Dial Plan->Replace Rule.
2. Enter the string (e.g., 1) in the Prefix field.
3. Enter the string (e.g., 1234) in the Replace field.
4. Enter the desired line ID in the Account field or leave it blank.

Hot Desking

Hot desking originates from the definition of being the temporary physical occupant of a work station or surface by a particular employee. A primary motivation for hot desking is cost reduction. This feature is regularly used in places where not all the employees are in the office at the same time, or not in the office for very long, which means that actual personal offices would be often vacant, consuming valuable space and resources.

You can use hot desking on the SIP-T20P/SIP-T20 IP phone to log out of existing accounts and then log into a new account, that is, many users can share the phone resource at different times. To use this feature, you need to configure a hot desking key in advance.

Note

If G722 codec is used for multicast paging, the LCD screen prompts "HD" to indicate that it is providing high definition voice.

Default codec for multicast paging is configurable via web user interface only.

To send RTP stream via a multicast paging key:

To send RTP stream via a paging key list:

1. Press the paging list key when the phone is idle.

1. Press OK to send RTP.
2. Press the Hold soft key to place the current multicast RTP session on hold.
3. Press ☐ to cancel the multicast RTP session.

Receiving RTP Stream

You can configure the phone to receive a Real Time Transport Protocol (RTP) stream from the pre-configured multicast address(es) without involving SIP signaling. You can specify up to 10 multicast addresses that the phone listens to on the network.

How the phone handles incoming multicast paging calls depends on Paging Barge and Paging Priority Active parameters configured via web user interface.

Paging Barge

The paging barge parameter defines the priority of the voice call in progress. If the priority of an incoming multicast paging call is lower than that of the active call, it will be ignored automatically. If Disabled is selected from the pull-down list of Paging Barge, the voice call in progress will take precedence over all incoming multicast paging calls. Valid values in the Paging Barge field:

• 1 to 10: Define the priority of an active call, 1 is the highest priority, 10 is the lowest.
- Disabled: The voice call in progress will take precedence over all incoming paging calls.

Paging Priority Active

The paging priority active parameter decides how the phone handles the incoming multicast paging calls when there is already a multicast paging call on the phone. If enabled, the phone will ignore incoming multicast paging calls with lower priorities, otherwise, the phone will answer incoming multicast paging calls automatically and place the previous multicast paging call on hold. If disabled, the phone will automatically ignore all incoming multicast paging calls.

To configure multicast listening addresses via web user interface:

1. Click on Directory->Multicast IP.

2. Select the desired value from the pull-down list of Paging Barge.

3. Select the desired value from the pull-down list of Paging Priority Active.

Enter the multicast IP address(es) and port number(e.g., 224.5.6.20:10008) which the phone listens to for incoming RTP multicast in the Listening Address field.

The valid multicast IP addresses range from 224.0.0.0 to 239.255.255.255.

Both the multicast paging sender and receiver's phones play a warning tone when establishing a multicast paging call.

Multicast listening addresses is configurable via web user interface only.

Music on Hold

Music on hold (MoH) is the business practice of playing recorded music to fill the silence that would be heard by the party placed on hold. To use this feature, you should specify a SIP URI pointing to a Music on Hold Server account. When a call is placed on hold, the phone will send a SIP INVITE message to the Music on Hold Server account. The Music on Hold Server account automatically answers the SIP INVITE messages and immediately plays audio from some source located anywhere (LAN, Internet) to the held party. Contact your system administrator for the SIP URI.

To configure music on hold server via web user interface:

1. Click on Account.

2. Select the desired account from the pull-down list of Account.

3. Click on Advanced.

4. Enter the SIP URI (e.g., sip:[e-mail]) in the Music Server URI field.

1. Click Confirm to accept the change.

When you placed a call on hold, the held party can hear the music.

Note

For this feature to function, all involved parties cannot use encrypted RTP.

Music on hold server is configurable via the web user interface only.

Message Waiting Indicator (MWI)

The SIP-T20P/SIP-T20 IP phone supports MWI when receiving a new voice message. If someone leaves you a voice mail, you will receive a message waiting indicator. MWI will be indicated in three ways: a warning tone, an prompt message (including a voice mail icon) on the LCD screen, and the MESSAGE key LED illuminates solid green. This will be cleared when you retrieve all voice mails or delete them.

The MWI service is unsolicited for some servers, so the SIP-T20P/SIP-T20 IP phone only handles the MWI messages sent from the server. But for other servers, the MWI service is solicited, so the SIP-T20P/SIP-T20 IP phone must enable subscription for MWI.

Note

MWI service is not available on all servers. Contact your system administrator for more information.

The MWI Subscription parameters you need to know:

Option	Description
Subscribe for MWI	Enable or disable a subscription for MWI service.

Troubleshooting

This chapter provides general troubleshooting information to help to solve the problems you might encounter when using your SIP-T20P/SIP-T20 IP phone.

If you require additional information or assistance with your new phone, contact your system administrator.

Why is the LCD screen blank?

• Ensure that the phone is properly plugged into a functional AC outlet.
• Ensure that the phone is plugged into a socket controlled by a switch that is on.
• If the phone is plugged into a power strip, try plugging it directly into a wall outlet instead.
• If your SIP-T20P IP phone is powered from PoE, ensure that you use a PoE-compliant switch or hub.

Why does the phone display "Network Unavailable"?

• Ensure that the Ethernet cable is plugged into the Internet port on the phone and the Ethernet cable is not loose.
• Ensure that the switch or hub in your network is operational.

Why does the phone display "No Service"?

The LCD screen prompts "No Service" message when no SIP account registers successfully.

Why doesn't the phone display time and date correctly?

Check if you have configured the phone to obtain the time and date from the SNTP server automatically. If the phone fails to connect to the SNTP server, you need to configure the time and date manually.

How do I find the basic information of the phone?

Press the OK key when the phone is idle to check the basic information of the phone, such as the IP address and firmware version. For more the basic information, refer to Phone Status on page 13.

How to obtain the MAC address of a phone when the phone is not powered on?

Three ways to obtain the MAC address of a phone:

• You can ask your supplier for the shipping information sheet which includes MAC addresses according to the corresponding PO (Purchase Order).
• You can find the MAC address on the label of the carton box.
• You can also find the MAC address from the phone's bar code on the back of the phone.

Why can't I get a dial tone?

• Check for any loose connections and that the phone has been installed properly. For the installation instructions, refer to Phone Installation on page 11.
• Switch between the Handset, Headset (if present) or Hands-Free Speakerphone to check whether the dial tone is present for one of the audio modes.
  If the dial tone exists on another audio mode, connect a different handset or headset to isolate the problem.

Why doesn't the phone ring?

Check that the ringer volume on the phone. To adjust the ringer volume setting, press the Volume key when the phone is idle. For more information, refer to Volume on page 25.

Why can't I receive calls?

• Check that the SIP registration with your system administrator.
• Check that the DND (Do Not Disturb) mode is deactivated on the phone. Refer to Do Not Disturb (DND) on page 63.
• Check that call forward is disabled on the phone. Refer to Call Forward on page 66.
• Check whether the caller number is stored in the blacklist directory. Refer to Blacklist on page 34.

Why is my handset not working?

Check that the handset cord is fully connected to both the handset jack on the phone and handset. Refer to Phone Installation on page 11.

Why is my headset not working?

• Check that the headset cord is fully connected to the headset jack on the phone. Refer to Phone Installation on page 11.
• Check that the headset mode is activated. Refer to Headset Mode

Activation/Deactivation on page 37.

- Check that the headset volume is adjusted to an appropriate level. Refer to Volume on page 25.

What will happen if I connect both PoE cable and power adapter? Which has the priority?

The phones manufactured before February 2010 use the power adapter preferentially, otherwise the phones use PoE preferentially.

What is the difference between user name, register name and display name?

Both user name and register name are defined by the server. A user name is used to identify the account while a register name matched with a password is used for authentication if the server requires. Display name is the caller ID that will be displayed on the callee's LCD screen. Server configurations may override local configurations.

Why does the phone play a tone when there is a call on hold? How to disable it?

When there is a call on hold, the phone will play a hold tone every 30 seconds. Play hold tone is enabled by default. Play hold tone and the interval of playing a hold tone are configurable via web user interface only.
