On June 30th 2015 an extra second will be added to the clock.

The Leap Second

We want to let you know about an important upcoming event, the “Leap Second” – and the steps DuoCall are taking to proactively protect your phone system and applications from being negatively impacted. The risk of impairment is low but it's always our practice to assure risk mitigation is thoroughly addressed and we want to take this opportunity to advise you of recommended proactive measures.

Are you ready for the leap second?

What is it?  

The Leap Second is an event that happens every few years when the standard time around the world is adjusted by one second to account for a slight mismatch between clocks and the Earth’s rotation. The IERS (International Earth Rotation and Reference Systems Service) has announced that on 30th June 2015 there will be a global adjustment resulting in a “Leap Second” being added.

Why is it important?

When the extra second is added there is a small risk that Unify applications running on Linux based systems may experience either a temporary or sustained impact to its operation. This is due to the Linux operating system having issues in handling the time synchronization messages which will occur when the extra second is added, and this can negatively impact the operation of applications running on these operating systems. Unify has developed and tested a series of preventive measures to prevent this problem from occurring in the operating system. We recommend that these measures be applied to the potentially vulnerable systems listed below prior to 30th June 2015.

Vulnerable Products

  • OpenScape Business V1 S (server based variant)/ Booster Server V1
  • OpenScape Business X1, X3, X5, X8 [embedded variants]
  • OpenScape Office V3R3.x, LX / HX (server based variants)
  • OpenScape Office MX V3R3.x

What does this mean for me?

As a DuoCall customer who utilises our maintenance and support services we will contact you to arrange an engineering visit. Due to the nature of your installation and how we deploy licenses through your server we will have to perform an upgrade to minimise the risk. Performing an upgrade will mean that the server is offline for the period of the upgrade.

Is there any action I need to take?

No, unless a member of the DuoCall Support team contacts you

Will there be any cost to my business?

No. DuoCall are providing this service to you as part of your maintenance and support contract as long as the upgrade is performed within your contract business times. If you require the upgrade to take place outside of our normal business hours a charge will be raised, this can be discussed during the call you will receive from the support team.
