Fixing Line Label Display in Polycom VVX devices on Version 5.7.x


Polycom have recently (few months ago) introduced the firmware upgrade version 5.7 for their VVX range devices. This firmware includes few of most wanted features for Skype for Business. Some of them are;

  • Common Area Phone support
  • SILK Codec support

Also, they have introduced a change to the DID number display on the device. This was an enhancement feature put in to VVX devices, when used with Skype for Business. In Polycom’s words;

“On VVX 300, 400, 500, and 600 series business media phones with the Skype for Business Base Profile, the Direct Inward Dialing (DID) number assigned to the user on the Skype for Business server displays on the on the Lock, Home, and Incoming Call screens. This feature is enabled by default on supported phones with the Skype Base Profile or shipped with Skype for Business enabled. The following figure shows the DID number on the Locked screen of a VVX 500 series business media phone.”

It looks like;

But, that’s on the Lock Scree. When it installed on a VVX 3xx device, it was looking like this on an unlocked device;file-5

When a standard user SIP URI is like sip:+618xxxxxxxx;ext=xxxxx where only 4 digit extension configure, it would have been fine.

But when the extension get lengthier than that, the DID number starting to get disappear to make room for additional digits in the extension. This looks really bad and confusing for the users who are using the device.

After escalating this further, Polycom have came up with a solution for this in their new firmware version 5.7.1. They have introduced a configurable option to change the number display, the way that the administrator wants.

The down side for this, is that a Provisioning server is required to fix this. If a provisioning Server already exist, then setting the below code in a configuration file will fix the display of the number to just to display the DID number. And not the full URI with the extension.

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!-- Generated features.cfg Configuration File -->
<polycomConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="polycomConfig.xsd">
 <up up.DIDFormat="NumberOnly"></up>
 <reg reg.1.useTelUriAsLineLabel="false" />
</polycomConfig>

Once this is configured and pushed in to devices, the number display will change to set as below;file-6

The display is way better with proper E.164 formatted DID number.

It’s a fairly straight forward fix for the environments that already have Provisioning server deployed. For others, not so much 🙂

PSTN calling for Microsoft Phone System and Teams in Australia


The PSTN calling plans for Microsoft Phone System (AKA Skype for Business Online) and for Microsoft Teams is finally here for Australia. Here in Australia, we call it as “Telstra Calling for Office 365”. 

It is bit different to how the service offering was done compared to other regions such as Americas and Europe. For Australia, if any organization wants to use Microsoft Phone System with Cloud PSTN, then they will need to directly engage with Telstra or, talk to one of the Telstra partners that are authorized to provide the service.

Other regions, organizations has the option to directly purchase numbers from O365 it self and assign to users. In this scenario, Microsoft act as the Telecommunications provider that provides the service. But, in Australia, Telstra is the Telecommunications provider that provides the service and not Microsoft it self.

However it is, the service is now available to use and lot of small to medium organizations was waiting for this to be available to complete their cloud migration goals. Since the announcement of service availability, few organizations are already lined up to register and many more to follow. It’s going to be busy and exiting months ahead.

For more information about the service, visit the Telstra web site.

Microsoft Teams


“Teams” is the new team based collaboration tool that was introduced by Microsoft few years ago. The key purpose of Teams is to compete with Slack and Zoom, which are commonly used team based collaboration tools in the market.

Teams is part of Microsoft O365 cloud based offering which needs to be enabled within the O365 admin portal. Once enabled, users can sign in to the application using Teams desktop client or using the Web client. Currently, Microsoft Teams and Skype for Business share most of features with each other. But, Teams still lacking some of key features that Skype for Business provides as a telephony platform.

Microsoft Teams is getting developed rapidly and more features getting added frequently. Below are the current available features and potential roadmap of additional features for Teams;

Based on current feature availability, Microsoft Teams is more than capable of supporting as the sole standard communications and collaboration tool. But, for complex environments that demand critical telephony features sch as Analogue integration, Contact centers, etc.., Teams might not be a good fit (yet). For such environments, Skype for Business will still be the ideal platform for communications workloads. Teams can still exist in such environments as only as the team based collaboration tool with limited features enabled.

Microsoft will continue to maintain both Skype for Business and Teams as collaboration platforms. It’s up to the end users to select which tool will suits their needs the most.
