PSTN number migrations
Starts: 2008/12/16 00:00 Ends: 2009/01/28 08:00
We will be changing the routing of some of our Geographic Number blocks so that inbound calls from the BT, Mobile and other PSTN networks is no longer handled by a 3rd party supplier, but is handled by our own telephone switching platform over the next couple of months. Our platform has been in use for over 18 months and already handles over half our traffic. Following other migrations we have done, we do not anticipate any problems with this migration, but there may be a small period of down time in the early hours of the mornings on migration dates, whilst the number routing changes are reflected in the BT Wholesale network. This work is to be completed in three stages:
