  Release Notes
System Software Version 3.21.23 is an important upgrade to version 3.20. It provides some essential software corrections as well as the all new DSX Phone Manager. The enhancements and corrections in version 3.21.23 are indicated by: [3.21.23]

Introducing the New DSX Phone Manager

Phone Manager

The new DSX Phone Manager allows an extension user to customize their telephone's features right from the convenience of their web browser. There is no special software to install on the user's PC. The DSX Phone Manager works with the DSX internal web server to let users tailor the most frequently-used features, including:

  • Call Forwarding
  • Settings for the telephone speaker, dialing, headset, and Off-Hook Signaling
  • Personal and Company Speed Dial
  • IntraMail mailbox settings (including Group Mailboxes)
  • Message Notification
  • Email Notification and Find Me Follow Me (with IntraMail Pro)

Easy to Access

To access the DSX Phone Manager, the extension user just needs to know the IP address of the DSX, have a PIN programmed, and an Access Level of 3 or higher. Just type the IP address in the browser address window, enter their extension number and PIN, and they're ready to go.


The DSX Phone Manager is intuitive and friendly. Since the browser interface is modeled after the Menu key options and the IntraMail user displays, the user is up to speed right away with no special training required.


The extension user can access the DSX Phone Manager at any time - while busy on the phone or while idle. The DSX Phone Manager won't interrupt their call or disable their phone during programming.

Special Features for Administrators

Admin Header

System Administrators (Access Levels 4 or 5) have a unique navigation bar in the DSX Phone Manager header that lets them program any other phone in the system. An administrator can program any option available to a user as well as some unique administrator-only options. These Admin Bar options include:

  • Extension PIN and Access Level
  • Mailbox Type, Admin Mailbox, and Message Limit
  • Company Speed Dial (view-only for users)

Installation Notes

To set an extension's Access Level (3 or higher required), go to:
    Stations: Config: Setup: Access: Program Level (2102-04)

To set an extension's PIN, go to:
    Stations: Config: Setup: Access: PIN Code (2102-05)

To find the system's IP address:
    Press CHECK + DND.

Enhancements and Software Corrections

Announcement Mailbox Options Not Being Saved [3.21.03]

The Announcement Mailbox Options IntraMail: Routing Mailboxes: Announcement Options: Number of Repeats and Hang up after Announcement are correctly saved in software version 3.21.03. In prior version 3 releases, the options could be changed in the System Administrator and phone programming but would not be saved in the system.

Ref: F100812001

Call Coverage Key Continues To Ring For Call Transferred To Busy UCD Group [3.21.23]

An outside line transferred to a busy UCD Hunting Department Group shows red on all line keys as it is waiting. If an extension has a Call Coverage key for the UCD Hunting Department Group master number, the user can press the key to pickup up the waiting call.

In prior version 3 releases, the waiting call would flash the line keys and could be picked up. If the call was picked up while the Call Coverage key was ringing, the key would continue to ring.

Ref: F101103003

Caller ID Handling of 16-Character Names [3.21.03]

The handling of 16-character Caller ID names is corrected in software version 3.21.03. In prior software versions, the receipt of a 16-character name could cause a variety of anomalies (including system reset).

Cordless DECT and Cordless Lite II Auto Detect [3.21.23]

Software version 3.21.23 will automatically detect the correct circuit type for the Cordless DECT and Cordless Lite II telephones (type 08). This allows the Phone Manger and the System Administrator to gray-out the feature keys that are not installed on the telephone. Grayed-out keys can still be customized, however, even though they are not physically installed. A new version of the System Administrator (not yet available) is required to correctly display all 8 keys on the Cordless DECT.

DID Intercept Not Sending Calls To Mailbox [3.21.03]

DID Intercept now correctly handles routing calls to an extension's mailbox. If an extension's DID Intercept is set for Busy/DND & RNA to 700, the user can:

  • Press DND.
  • Let DND time out to DND All Calls, and
  • Have DID Intercept automatically route all their DID calls do to their mailbox.

In software versions prior to 3.21.03, the DID calls would incorrectly route to the Automated Attendant instead.

DID Translation With Destination 999 Routes To Schedule [3.21.23]

If the DID Translation Table destination set in Lines: DID: Setup: Translations (3302) is 999, the incoming call will overflow to the associated Schedule (if any). In prior version 3 releases, the translation had to be an undefined extension (e.g., 427) to overflow to the Schedule.

Directory Dialing Scrolls to Next Extension's Bin [3.21.03]

A software error is corrected in version 3.21.03 which allowed Personal Speed Dial Directory Dialing in prior versions to scroll to the next extension's first bin. An extension user could, for example, push DIR + PER and press Volume Up to scroll through their Personal Speed Dial. They would see, however, the first bin for the next consecutive extension correctly alphabetized within their own list. This no longer occurs.

A potential Personal Speed Dial Directory Dialing scroll problem is also addressed in this release. In prior releases, it was possible for the names to be out of order when two extensions were scrolling simultaneously.

Ref: F100701001

Full Duplex Speakerphone Enabled When On a Call with an IP Keyset [3.21.03]

When an IP keyset lifts the handset and calls a TDM keyset, the TDM keyset's Full Duplex Speakerphone (if available) follows the settings of Stations: Config: Options: Speaker: Disable Full Duplex Speakerphone (2112-07). In software versions prior to 3.21.03, the Full Duplex Speakerphone would always be disabled for this type of call.

Headset User Locks Up Page Port [3.21.03]

A headset user Page lockup condition is corrected in software version 3.21.03. The lockup would occur as follows:

    1. An extension user on a headset, in the headset mode, makes a Page.
    2. During the page, another extension places a voice over to the headset extension and hangs up before the paging is complete.
    3. The Page zone is now locked to the headset extension. All calls to and from the headset extension broadcast over the Page and paging is unavailable to all other users.

A system reset was required to correct the problem.

In system software version 3.21.03, Voice Over is prevented in this context.

Ref: F100802005

IntraMail Conflict Between Pause and Disconnect Corrected [3.21.04]

Software version 3.21.04 corrects an IntraMail race condition between Pause Due to Silence and Disconnect which would cause a system reset.

Page Alert Beeps Can Be Optionally Disabled [3.21.23]

Telephone programming option 1513-03: Paging Alert enables and disables the alert beeps that precede a paging announcement. If enabled, the Page alert beeps occur normally just before the announcement begins. If disabled, the alert beeps will not occur. This option is enabled by default.

Park and Page During Page Broadcast Resets System [3.21.03]

In software versions prior to 3.21.03, a system reset could occur if IntraMail Park and Page attempted to broadcast a Paging Message when the zone requested was already in use. In software version 3.21.03, Park and Page will queue for the busy zone and broadcast the Paging Message when the zone becomes free.

Ref: F100816002

Parking an Intercom Call Prevented [3.21.03]

With software version 3.21.03, extension users are automatically prevented from placing their active Intercom call in a Park Orbit. Although Intercom Park was not supported in prior software versions, a user on an Intercom could still press a Park key. This could result in the extension having a continually flashing INTERCOM key, one-way speech path, and other anomalies.

A system reset was required to correct the problem.

Phone Manager: Admin Bar Improvements [3.21.23]

The operation of the Phone Manager Admin Bar is improved:

  1. If the administrator enters an illegal extension number, the system ignores the entry and leaves the Phone Manager on the current page. In prior versions, this operation would force a logout.
  2. The administrator can navigate to another extension by typing the extension number and pressing Enter or the tab key. In prior versions, only the Enter key would accept the entry.
  3. Typing a new extension in the Admin Bar and clicking anywhere else on the page will restore the current entry.
  4. The Next and Prev buttons skip extensions that are not in the system's numbering plan. In prior versions, this operation would force a logout.
  5. Clicking Prev while on the lowest-numbered extension and clicking Next while on the highest-numbered extension are ignored. In prior versions, this operation would force a logout.

Phone Manager: Key Assignments Now Available [3.21.23]

Phone Manager users can click Features: Key Assignments to set up their Feature Keys. To customize a key:

  1. Log into the Phone Manager and click Features: Key Assignments.
  2. Click the key you want to change. The key automatically loads into the Key Assignment box.
  3. Select the key in the Key Type drop down list and add any additional data required in the Entry box.
  4. Click Enter to load the key onto the page and change additional keys as required.
    • The keys that you change will stay red.
  5. When you're done, click Save to send your changes to the system.

Phone Manager: Call Forward to Illegal Destinations Blocked [3.21.23]

The Phone Manager in software version 3.21.23 discards Call Forwarding entries to Routing Mailboxes and line extension numbers. It also discards entries that would set up a Call Forwarding loop. In prior Phone Manager versions, entering a Call Routing Mailbox as the forwarding destination could result in a system reset.

Ref: F101118003

Phone Manager: Multiple Email Addresses Allowed [3.21.04]

To allow for the entry of multiple email addresses, the Email Notification: Email Address entry can contain any combination of characters, 48 characters maximum, excluding: % | = " $ \

Phone Manager: Numbers can Begin with * # F P [3.21.04]

Speed Dial, Message Notification, and Find Me Follow Me telephone numbers can begin with *, #, F (for Flash) or P (for pause). In version 3.21.03, the numbers could contain these entries but they could not be the first digit.

Phone Manager: Programmable Port Assignment [3.21.23]

Telephone Programming Option 1104-07: Phone Manager Port sets the port on which the Phone Manager will communicate. The default is standard HTTP port 80 but you can set the port anywhere within the full port range of 1-65535. Note that browsers and company LANs may restrict which ports are available for HTTP traffic, so be sure to check with the site IT Manager before changing the port.

To use an alternate port, append the port number to the phone system IP address. For example: will connect to the Phone Manager at on port 8080.

PIN Code Length Enforced [3.21.03]

The PIN code set in Stations: Config: Setup: Access: PIN Code (2102-05) must be 4 digits long. In software versions prior to 3.21.03, the system would accept a partial PIN code of less than 4 digits from the System Administrator. However, a PIN code less that 4 digits would not function. This is now corrected to ensure that only 4 digit PIN codes will be accepted.

PRI Call Tries To Dial Out If Second Line/Loop Key Presses [3.21.23]

If an extension user:

  1. Presses a line or loop key for a PRI line,
  2. Partially dials the call,
  3. Then presses another PRI line or loop key,

the first call will be torn down and the user will get new dial tone on the second line. In software versions prior to 3.21.23, the initial line would attempt to dial out as soon as the user pressed the second key. This no longer occurs.

Ref: F101110006

Schedule Skip Cancelled if Next Schedule Entry is in the Following Week [3.21.03]

If a keyset user presses their Skip Ahead key and the next Schedule Entry is for a day in the following week, the system will use the next consecutive Schedule Entry instead. For example:

  • Schedule Entry 1 is set for every day of the week from 9:00 AM to 5:00 PM.
  • Schedule Entry 2 is set for all other times.
  • On Saturday at 11:30 AM, the extension presses their Skip Ahead key.
  • The schedule automatically advances to Schedule Entry 1.

In version 3 software prior to 3.21.03, this condition would cancel the schedule skip. This is now corrected.

Ref: F100823003

Spanish Displays Available on DSX Keysets [3.21.23]

DSX keyset display messages are available in English or Spanish. To change the display language, use the Phone Manager Features: Name and Login: Display Language option or telephone programming option 2101-03: Station Display Language. Spanish displays were not available in prior Version 3 releases.

Ref: F101019001

Speech Path Lost After Multicast Page [3.21.03]

A lost speech path problem with Multicast Page is corrected in software version 3.21.03. Here is an example of when this could happen in prior versions:

  1. Enable Multicast Paging for all IP keysets in Stations: Config: Setup: VoIP: LAN Multicast.
  2. A keyset user answers an outside call, places it on Hold, makes a Page, and hangs up.
  3. A user at a IP Keyset presses a line key to pick up the call from Hold.
  4. The IP keyset user has no speech path with the outside caller.

This is now corrected.

T1/PRI Clock Sync Corrected When Multiple Cards Installed [3.21.03]

A clock sync issue is corrected in software version 3.21.03 affected the second T1/PRI card in a two card installation. On power up, the first card that became operational would correctly become a clock slave to the service provider's clock source. When the second card became operational, it would come up in the master mode and not rely on the provider for clock source. With certain service providers this could result in timing slips which could in turn create talkpath loss and other issues.

Software version 3.21.03 corrects this problem by ensuring that both cards in a two card installation use the service providers master clock as the clock source. Both T1/PRI cards operate in slave mode.

This correction also requires T1/PRI Card firmware version 4.7 which is automatically provided as part of this update.

Ref: F100802006

T1/PRI Lines Don't Recover After System Reset [3.21.23]

T1 configuration is correctly restored after a system or card reset. In prior software versions, a T1/PRI Card set for T1 operation could operate with the default ESF/B8ZS settings after reset, regardless of the programmed configuration. If the connected service did not support ESF/B8Zs, the card would not recover.

Ref: F101118002

VoIP: No Audio Between Analog Door Box and IP Keyset [3.21.23]

The following DSX-40 Analog Door Box problem is corrected in software version 3.21.23:

  1. Analog Door Box 1 (327) and local IP keysets 401 and 402 are in Department Group 1.
  2. Door Box 1 is set to chime in Stations: Config: Setup: Type: Door Chime (2101-04).
  3. The caller at the door presses the Door Box call button, the IP keysets chime, and the caller at local IP 401 lifts the handset to answer the call.
  4. There is no audio between the IP keyset and the Door Box. There is also no audio on subsequent Intercom calls from the IP keyset to any TDM extension.

This issue is now corrected.

VoIP: IP Keysets Provide Additional Messages When They Can't Connect [3.21.23]

DSX IP Keysets provide one of three diagnostic messages when registration with the system fails:

  • Invalid Password
    • The system entry in Stations: Config: Setup: VoIP: Password (2106-02) and the keyset Admin entry in 2:SIP Settings -> 1:SIP User -> 2: Password don't match.
  • Unknown Extension
    • The extension number entered at the keyset in 2:SIP Settings -> 1:SIP User -> 1: User ID and 3: Extension Number doesn't exist in the system.
  • SIP Server Not Found
    • The DSX IP Keyset cannot register over the LAN or internet to the system (SIP Server).

VoIP: System with Public IP Can't Detect Remote RTP Port [3.21.03]

A VoIP enhancement is made in system software version 3.21.03 that allows a DSX system with a public IP address to correctly detect the RTP port used by the remote router. In prior version 3 releases, this could cause a correctly registered remote IP keyset to not have a speech path. This was a router-dependent issue that did not occur in all cases.

Walking Class of Service Timer Didn't Expire [3.21.23]

When a user implements Walking Class of Service at a co-worker's extension, the Walking Class of Service automatically expires 10 seconds after the extension goes idle. In prior Version 3 releases, the timer would never expire.
