NEC DSX software version 3.11 preview
DSX System Software Version 3.11 is an important new release that features three major VoIP enhancements: Peer-to-Peer communication between IP extensions, NAT Traversal with Any Router, and Improved ATA and SIP SLT Support.
In addition to multiple bug fixes, DSX System Software Version 3.11 also provides the new IntraMail Message Review feature, enhanced Cascading Message Notification with IntraMail Pro, and improved maintenance functions when used with System Administrator 3.11 or higher.
DSX Software version 3.11 is currently in Beta.
Important New System Features
Peer-to-Peer (p2p)
IP keysets, ATAs, and SIP SLTs connected to another SIP device in the same office do not use VoIP Gateway circuits. They communicate p2p instead. This means you can have 32 SIP devices in an office talking to each other and never use up a VoIP License.
A VoIP License is still required, however, when a SIP device is:
- On an outside call.
- Participating in a Conference.
- Using Room Monitor.
- Using an IntraMail mailbox or leaving a message.
- Calling a SIP device in another office. - For example, if an on-premise IP keyset calls an IP keyset in a remote office, each IP phone requires a VoIP License.
By default, Peer-to-Peer is enabled for all IP extensions. The system will automatically switch VoIP gateways in and out as required by the call state.
NAT Traversal With Any Router for DSX IP Keysets
NAT Traversal is available with any router without programming. You no longer have to limit your remote offices to the two LinkSys routers we previously recommended.
To set up NAT Traversal:
- On the phone system router, forward UDP ports 5060 (SIP) and 1024-1088 (RTP) to the DSX system IP address.
- On the DSX IP Keysets, use IP Keyset firmware 1.0.7.2 or higher.
- Improved ATA (Analog Telephone Adapter) and SIP SLT Support
Major improvements have been made to the DSX integration with third-party ATAs and SLTs. In general, ATAs and SIP SLTs work the same as local analog single line sets.
Internal Modem Automatically Disabled when VoIP Daughter Board Installed
To protect the viability of VoIP resources when the VoIP Daughter Board is installed, the internal modem is automatically disabled. The reliability of DSX VoIP could be compromised if both were enabled simultaneously.
Hot Dial Pad Follows Prime Line
If an extension has Hot Dial Pad enabled 2111-11:Hot Dial Pad and a Prime Line Set in 2114-01: Prime Line, any digits the user dials on the dial pad will go out over the Prime Line. In prior versions, Hot Dial Pad would always follow Intercom Prime Line.
Hotline Keys for Voice Mail Ports
An extension user can assign IntraMail ports (501-508) to Hotline keys in Menu: Key Assignment: Feature Keys (Menu + 51). This can be a useful visual tool for monitoring voice mail port usage.
Additional Silence Elimination for Messages
IntraMail will automatically remove 4.5 seconds of silence from any message recording that is paused due to silence. In addition to cleaning up normal messages, it will also help to eliminate “hang up” messages because they will be too short to be saved.
Important New IntraMail Features
Message Review
After a caller leaves a message they can review their message before sending. After reviewing the message they can rerecord it, erase it, or send it to the recipient unchanged. Message Review is available to both co-workers and outside callers.
Cascading Message Notification Enhanced
For added flexibility, IntraMail Pro Cascading Message Notification now allows multiple cycles through the list of destinations. You can, for example, have notification cascade through each destination once and then repeat the cycle. Additionally, the number of busy and RNA attempts per destination can be from 1-99, and the total number of notification cycles can also be from 1-99. This allows for very complex notification cascades if the site requires.
The meaning of the following timer has changed to accommodate these enhancements.
4202-06: Maximum Attempts sets how many times Message Notification cascades through the list of destinations.
IntraMail Maintenance and Prompt Update Features
System Software 3.11 enables all the System Administrator Version 3 Maintenance and Prompt Update features. This includes:
- Copying, moving, and erasing mailboxes.
- Deleting voice prompt sets that are already installed (e.g., to make more message storage room).
Automated Attendant Call Progress Tone Detection
If an outside line without loop disconnect supervision is answered by the Automated Attendant, and caller hangs up, Call Progress Tone Detection will detect the busy, reorder, or dial tone on the line and hang up. This prevents the call from timing out to the Dial Action Table Timeout destination and, in some configurations, inadvertently setting up a loop.
Software Corrections
* Multicast Paging for All Page Zones
Multicast Paging is now implemented for zone page as well as all call. In prior releases, Multicast Paging was inadvertently restricted to All Call only. This caused zone paging to be unavailable to IP keysets.
* T1/PRI Firmware 4.4
T1/PRI Card Firmware 4.4 corrects the following issues
- Allows backplane synchronization with multiple cards.
- Enables Presentation Restriction in outbound Caller ID.
- Handles Disconnect with Cause if Release is received prior to Call Proceeding.
