XSTIM Settings

Before you start creating extensions for XSTIM phones, you should review the system wide options configured under XSTIM Settings.

To configure common options used for any XSTIM phone (E-MetroTel, Nortel, Avaya, Panasonic), perform the following steps:

  1. Open the UCX Web-based Configuration Utility
  2. From the PBX tab, select PBX Configuration
  3. From the left side column, select XSTIM Settings
  4. Review the configured defaults
  5. If you made any changes in the settings, press the Submit Changes button to save the configuration

You should at least review and update the options described on this page as needed:

Jitter Buffer Settings

If you have XSTIM devices that are not located on your local subnet, you should set the Jitter Buffer option to Enabled

Quality of Service Settings

If you want to configure Type of Service or Class of Service parameters, enter the values in the appropriate TOS or COS fields.

Audio Codecs

Select the desired codecs, all others will be disabled. You can click and drag to reorder the codec selection.

To obtain the full functionality of codecs g729 or g723, you must install an optional licensed package with codec modules. If these codecs are used without the modules, functionality will be limited to media pass-through between endpoints.

Display Options

If you want your company name shown on the display of XSTIM phones, enter the name in the Title Default field. The maximum number of characters displayed on the Title Default field is 12.

If you want additional textual information shown on the display of idle XSTIM phones, you can enter it in the Main Text X field(s). The maximum number of characters that will be displayed is dependent on the type of set. 

If Main Text 0 is left blank, the words "Powered by UCX" are displayed
If Main Text 1 is left blank, "extension@hostname" is displayed.
If Main Text 2 is left blank, the IP address of the phone will be displayed.

If you wish any or all of the fields in the Display Options section to be completely blank, simply enter the word blank (no quotes, non-case sensitive) in the input field for Main Text 0, Main Text 1, and/or Main Text 2.

Advanced General Settings

Field Description
Port If you want to change the default port number (7000) that is used by the UCX system for communication with XSTIM phones, enter the desired port number in this field
Public IP

If XSTIM phones will be connected to your UCX system from an external network and your system is behind NAT, you must enter your public IP address in the Public IP field

Auto Dial Timer Digits are dialed if the user does not press a key within this amount of time. The value is entered in milliseconds, with a default of 4000 (4 seconds). A value of 0 disables the feature.
Additional Call Display Timer

The amount of time to display information on an incoming call alerting on an XSTIM phone while the phone is still active on another call.
The value is entered in milliseconds with a default value of 5000 (5 seconds). The minimum is 1000 (1 second) and the maximum is 60000 (60 seconds). Any value less than 1000 will default to 1000 and any value greater than 60000 will default to 60000.

This setting is available for software releases 4.5 and up.

Held Line Reminder The Held Line Reminder or On-Hold Reminder is Enabled by default. You can change the reminder interval or turn it off. This feature applies to external calls only.
First Key Position Default position of the first programmable key (i.e. the key with the first line appearance) on an XSTIM IP phones. The values are Right bottom (default)., Left bottom. Right top, Left top.
(Note: If you are using Panasonic digital sets, you must leave this setting as the default value, although the first key will actually appear on the Left Bottom of Panasonic phones.)
Audible Call Waiting For Call Waiting indication, there are 3 options under Audible Call Waiting: (None, Ring, Buzz) The default is attenuated Ring which is two levels lower than normal ringing volume.
Ring Cadences

Different Ring Cadences can be configured for External Calls, Internal Calls and Ringing BLF buttons. Below are the cadence values.

Cadence Setting
Continuous Uninterrupted (2 seconds)
Short-Long Interrupted (0.5 s ON, 0.3 s OFF, 1.2 s ON)
Medium-Medium Interrupted (0.7 s ON, 0.5 s OFF, 0.7 s ON)
Phone State After Auto-answer The state of phones after auto-answering an incoming paging or intercom call.

Soft Key Transfer Type

* (See note below)

Sets the default value for the type of transfer invoked using the Transfer softkey on XSTIM sets.

Attended: This is the default setting for new systems. This mode enables the XSTIM based softkey user interface for collecting and editing dialed digits. The Transferor has the option of talking with the Transfer-to party prior to transferring the call and can complete or cancel the transfer using softkeys.

Asterisk Blind: In this mode, digit collection is performed using inband signaling and there are no options to cancel the transfer. The Transferor does not have the option of talking with the Transfer-to party prior to transferring the call.
Asterisk AttendedIn this mode, digit collection is performed using inband signaling. Once the transfer-to number has been dialed, context-sensitive softkeys will be presented to the transferor for completing the transfer, canceling the transfer, or conferencing both parties into a three-way call.

Note: this setting will be used for ALL XSTIM extensions that have not explicitly been assigned a Softkey Transfer Type setting in the Extensions (XSTIM) configuration page. Take care when changing this setting on an existing system.

See feature description for more details: Call Transfer and Recall.

Attended Transfer Number

(see note below)

The caller ID number used for attended transfers.
First Line for Calls Without Name

Contents of the first display line of an XSTIM phone when the phone receives an incoming call from an endpoint with an unknown caller ID name. By default, the CallerID number is shown on both the first and second line.

This setting applies only to phones with 3 line displays (e.g. 1140E).

Dial Pad Feedback The default dial pad feedback for UCX devices (XSTIM IP phones).
Live Dial Pad Allows dialing without selecting a line key or lifting the handset.
Hotdesking If you want the Hotdesking feature to be available on XSTIM phones, set the Hotdesking option to Enabled. See Hotdesking feature description for details.
Hotdesking Message When a phone is hotdesked to another extension, show a notification message on the phone's display.
Feature Key Mode The Feature Key Mode field is Enabled by default. When enabled, it makes XSTIM Phones operate like Nortel BCM phones, where features and key labels similar to BCM phones are used. See Feature Key Mode for details.
Note: When Feature Key Mode is enabled, XSTIM phone users will not be able to press their Line extension key twice as a shortcut for the Last Number Redial function.
Offhook Answers Ringing BLF When this option is enabled, an incoming call alerting on a ringing BLF key is answered when the user goes offhook. When this option is disabled, the user must press the ringing BLF key to answer the incoming call.
Ringing BLF Active+Ringing State This option controls the state reported on a ringing BLF key when the target phone is on an active call and another incoming call is alerting on the target phone. Any sets with a ringing BLF associated with a target extension that is already busy when another call arrives for that extension will not provide a ringing alert while the setting is configured as Active (which is the default).  When set to Ringing the sets with a Ringing BLF will provide audible ringing regardless of the original state of the target extension.
Set Based Configuration See Set Based Configuration feature description for details.

Other XSTIM Settings

** (See note below)

This field should only be used with direction from E-MetroTel support.


Note: The Attended Transfer feature using the Transfer softkey can be disabled independent of the Asterisk In-Call Attended Transfer setting. To disable the ability to use the Transfer softkey for Attended Transfer enter the string no_attended_transfer in the left side of the Other XSTIM Settings field and set the right-hand value field equal to 1.
** Note: The label displayed for softkey MSB can be changed to DND by entering the string dnd_label in the left side of the Other XSTIM Settings field and set the right-hand value field equal to 1.

Dialing Options

You should enter dial plan patterns that match your dial plan in the Dialplan Patterns area.

Dialed digits that match patterns defined here will allow XSTIM phones to complete the call without having to press the Send or # key. 
These patterns can also include the timeout option (T), that allows dialing to start after the configured dial timer expiry (default is 4 seconds).

Pattern Description
x Matches any digit 0 - 9
[1,2,3-5] Matches any digit listed including ranges
. Matches all digits
T Matches Dial Timer expiry


Note: As shown in the example above, if a user dials the digits 911, the UCX will immediately complete the call via the appropriately configured Outbound Route without waiting for an end of of dial timer or key press. E-MetroTel recommends that all emergency numbers, even included the dial sequence 9911 be configured as a Dialplan Pattern to minimize the time for an emergency call to be establishe when using XSTIM phones.

You can override some of the default settings configured on this page with device specific settings configured on the XSTIM Properties page of each phone.
