What are the differences between Polycom’s VVX-0 and VVX-1 models?

You may have noticed Polycom has launched some new VVX models. These models have new names and now end in a ‘1’ instead of a ‘0’, for example, the VVX 301 is the new version of the VVX 300.

With little visual changes, we are putting this blog together to help to explain what’s changed and why.

The new models are the 301, 311, 401, 411, 501, 601 and the old models are the 300, 310, 400, 410, 500, 600.

The most notable change is that the new VVX 401 and 411 models now come with a USB port. Other than this the only real changes are an upgrade to the phones’ processor and memory performance.

With the refresh to the VVX portfolio, the updated models offer users investment protection as they have been developed with the active development lifecycle in mind.

There are no plans yet to discontinue the old VVX models, however this is inevitable and eventually, the new VVX models will replace their predecessors.

RTX 4002 ‘End of Life’ Notice

RTX have discontinued their 4002 repeater, we have now sold our final remaining unit of this product which has been replaced by the new 4022. The 4022 is very similar to the old 4002, with just a couple of adjustments.

What’s New?

  • 2-colour LED for radio link quality indication
  • New dedicated programming key for easy reset and configuration of repeater
  • One SKU for both Europe and the UK (4022 comes with both power supplies)

Differences between the Yealink T4 and new T4S Series

What’s new
Visually the new T4S series is identical to the equivalent model in the T4 series, however, Yealink have been working on a number of enhancements and reasons to move over to the T4S series:

  • Device performance enhancement: The T4S phones use the latest components to maximise the models’ performance and boost the user interface response rate.
  • Future-proof: As Yealink continue to add new and more powerful features to their phones’ firmware they will in turn require a higher level of hardware support. The new T4S’ are future-proof as they are equipped with new hardware components to allow the phones to support future firmware upgrades.
  • Opus support: Opus is an increasingly popular HD codec, especially in the carrier / ITSP market for use with WebRTC. This will provide the T4S models with a competitive edge.
  • Enhanced speaker performance: The T4S utilises new speaker components to maximise acoustic performance over the devices’ speaker phone.
  • USB ports: The new T41S and T42S models feature a USB port. The USB port allows for increased functionality with support for either the BT40 bluetooth dongle, WF40 Wi-Fi dongle or a compatible USB headsets.
  • Unified firmware: The new hardware for the T4S series allows for a unified firmware across the model range making management and provisioning easier and more convenient.
  • HAC handsets: All T4S models will be supplied as standard with a Hearing Aid Compatible (HAC) handset.

Please note, the new T4S phones will support V81 and later firmware. The firmware which supports T4S phones is different from the one which supports the current T4 series.

Trade pricing and RRP of the new T4S models will be the same as the equivalent model in the existing T4 series of phones.

As you may be aware, Yealink have been busy working on a new range of IP desk phones. Expected to be available to purchase in September 2017, the new T4S series will be the next generation of the popular T4 series – Here’s a sneak peek of what to expect!

ITSPA updated recommendations for provisioning security



ITSPA has recently released a new guidance paper surrounding remote provisioning of phones and other SIP devices. This new document shares best common practices among ITSPA members to help ensure their provisioning infrastructure is secure.

ITSPA Chair Eli Katz stated

This is an excellent update to the existing guidance and should be considered a starting point rather than a complete solution. This is just a part of ITSPA’s ongoing work in tackling cyber-crime and fraud as well as driving up best practice within the membership. We must ensure the industry is one step ahead in the security battle.
