NEC has released a new software version for the UX5000 telephone system.  Among the new features is the long awaited ability to do VoIP networking and remote keysets with NAT Transversal.  Previously a VPN connection was required for a remote VoIP keyset to access the NEC UX5000 telephone system.

Highlights of the NEC UX5000 software version 3 include:

Software NAT Traversal / NAPT (Network Address Port Traversal)
This software, which requires a NAT license, provides the ability to establish communication
with the UX5000 and RTP communication among UX5000 multibutton IP terminals through
Network Address Translation (NAT) on an IP network. With NAT Traversal there is no need to
have a VPN connection for an outside UX IP terminal user to be able to access the UX5000.

Caller ID Pass-Through for Mobile Extension Calls
With previous operation, an incoming trunk call into the UX5000 routed back out to a Mobile
Extension user would show the Caller ID information from the UX5000 – not the outside trunk.
With this enhancement, a call routed over an ISDN, SIP or analog trunk to a Mobile Extension
will now display the Caller ID information from the original outside call.

Analog Trunk Support Added for Mobile Extension
Mobile Extension over analog trunks is supported in this release.

Upload/Download of Voice Prompts/Messages
For the UX-IntraMail, the ability to upload/download the voice prompts has been added. This
feature enables uploading/downloading of audio files in PCM format (WAV file) to the Compact
Flash card in the IntraMail via UserPro/AdminPro. The user can backup or playback recorded
greetings on a PC or install greetings/MOH. (Note: Regular IntraMail/VRS messages are
recorded in ADPCM format which cannot easily be opened on the PC.)

ISDN: Caller ID Name on Outgoing Calls
It is now possible for outgoing ISDN calls to show the Caller ID name. With previous software,
only the number could be sent.
