The works will only affect you if you have configured a Firewall for your HV-Select hosted voice services. If you have then you will need to add a new Firewall Rule. Please ensure that your IT company or support staff add the new Rule BEFORE 17:00 on Monday 18th June and to be safe you are able to add the new Rule straightaway.
What is happening?
Daisy/BT are adding a Primary Platform IP Address (SBC destination Subnet) 22.214.171.124/26. This is the address that the IP phones look at when connecting to the HV-Select platform.
Why is this being done?
To increase the HV-Select platform capacity and accommodate future growth.
What do you need to do?
Ensure that Routers and Firewalls relating to your HV-Select installations are updated to allow the new range to pass through any restrictions. For example: if you have a Firewall in place a Rule will need to be added to allow the above Subnet range to pass through. IF YOU DO NOT HAVE A FIREWALL, THEN NO RULES NEED BE APPLIED. PLEASE NOTE THAT NO EXISTING RULES SHOULD BE REMOVED, ONLY THE NEW ONE ADDED
What is the impact of no action?
If you do not add the above Rule, then you will suffer loss of telephone service and all HV-Select devices will lose the ability to communicate with the HV-Select platform.
