We are aware of a problem with an upstream provider that is preventing the termination of OFFNET (Mobile, Local, National and international) calls. We are currently working to resolve the fault and will provide updates shortly.
UPDATE01 – 11:36
Local and national calls should now be terminating correctly, however mobile calls are still resulting in a BUSY response from our carrier.
UPDATE02 – 12:00
Mobile and international calls are now terminating correctly.
We have logged a case with the carrier for details and will provide this once made available.
We apologise for any inconvenience caused
UPDATE03 – 12:24
We have been advised the root cause of the failure was “a major outage on the BT IP exchange interconnect which caused a high proportion of calls to fail.”
In light of this outage, Structured Communications will be implementing carrier diverse outbound routing. This will require large network changes and further details to follow in the coming weeks.
