  DSX System Software 3.44 Overview
  Enhancements and Software Corrections
  • Call Forwarding Off Premise
    • Call Forwarding Off Premise (Outside Calls Only) is now handled correctly when a call is transferred from the Automated Attendant. In version 3.34, this type of forwarding would fail.
  • Ethernet Setup
    • System: Config: Communication: Ethernet (1104): Renew is now functional when DHCP: DHCP Enabled is set to Yes with Manual IP. Previously this option was not functional.
  • Headset Compatibility
    • The ability of WHA/headset users to "surf" hotline keys while on an active call has been restored. Software version 3.43.11 inadvertently introduced a potential disconnect while surfing.
  • IntraMail
    • When a mailbox user is logged into their mailbox, any messages marked for handling (e.g., delete) will be processed after the user logs out. In version 3.34, an attempt to log into a busy mailbox could cause the processing to occur while the initial user is still logged in.
    • Tone detection handling is improved to ensure that tones dialed to initiate Park and Page do not interfere with the message being broadcast.
    • The background process for handling Automated Attendant Transfer to Speed Dial is improved.
    • To prevent authentication errors, the "From" field in an email notification now includes the SMTP credentials.
    • IntraMail: Config: Setup: Options: Default Interface (4203-03) is added to set the IntraMail default prompt interface (numeric or mnemonic).For example:
      • If a station leaves a message in another station's mailbox, IntraMail uses the calling station's language and prompt interface. In prior versions, the system default language was always used.
      • If the calling station does not have a mailbox, IntraMail uses the system default language and prompt interface. (In prior software versions, this case always used the mnemonic prompt interface.)
  • Message Center
    • When a user on an outside call presses a Message Center key to transfer the call to voice mail, SPEAKER will extinguish. In prior software versions, SPEAKER would remain on.
  • ML440
    • Compensation has been added for an ML440 issue which would cause the handset not to respond to an End key press.
    • (3.43.04) Various corrections have been made to improve the overall reliability and stability of ML440 operation.
    • (3.43.09) The system will no longer send redundant Speaker/Handset control messages. For example, the system will not send a message to turn off the speaker or handset if it is already off. In prior software releases, this could cause misoperation of the ML440.
  • Paging
    • Wireless keysets such as the ML440 and Digital Cordless DECT are now excluded from the Paging process. In prior releases, Paging would be set up and added for these extensions even though there was no way for the keyset to broadcast the page. This would needlessly consume system resources.
  • Phone Manager
    • Using Phone Manager to program Find Me Follow Me or Message Notification will leave any Day of Week Scheduling untouched. In version 3.34, making a change to these features from Phone Manager would disable the scheduling.
    • The Off Premise Call Forwarding destination will now correctly display in the Phone Manager. In prior versions, destinations with an odd number of digits would display incorrectly.
  • Prime Line Preference
    • On an extension with Prime Line to trunk group, the user can lift the handset and immediately press a key for another feature. In prior software versions, there was a very short duration of time where this could misoperate.
  • Programmable Function Keys
    • Telephone program 2121 can now correctly access and set programmable keys 13-24 on 34-button keysets. In version 3.34, only keys 1-12 could be set from telephone programming.
  • Speed Dial, Personal
    • When using the User Programmable Features to set up Personal Speed Dial, the user can press a One-Touch key to select the bin to be programmed. In version 3.34, this would incorrectly select the previous bin.
  • System Processes
    • Due to some background timing changes, the system is now less likely to reset while under extreme processing load.
  • Temperature Display
    • The Temperature Display reliability is improved. Also, negative temperatures should now always correctly display.
  • VoIP
    • A correction is added that minimize the likelihood of a VoIP lockup that would require a system reset to clear.
    • A correction is added to ensure that the correct parties are connected after an ATA user hookflashes.
    • Several corrections to the way the system handles Paging and IP extensions have been added. These corrections should improve the reliability of IP extension registration and page handling.
    • In this software release SIP messages received from the network have priority over SIP messages generated by the DSX. In prior versions, the priority was reversed and SIP endpoints could deregister during periods of high messaging.
    • State processing is improved to ensure that active processes are logically aborted. This prevents, for example, a condition at an IP keyset where a user on an outside call could press INTERCOM, dial a Page zone, but get no speech path to the zone.
    • To further increase messaging efficiency and minimize the potential for registration timeouts, the method used to update the display time has changed.
    • Incoming SIP trunk calls in which the caller dialed *67 to block their caller ID are now correctly handled. In prior versions, the DSX could disconnect blocked caller ID calls depending on the handling by the SIP trunk provider. (DSX is now compatible with "anonymous.invalid" specified in RFC 3323.)
  • Wakeup Call
    • Wakeup Call to 2-digit extension numbers is now functional.
    • In prior software versions, adding a 16th Wakeup Call would cause the browser display to go blank until an older Wakeup Call cleared. This is now corrected. Note that the maximum number of Wakeup Calls that can be displayed is 25.
