Nowcomm has notified our Customer Services Centre, who are ready to identify and resolve any issues that may arise in any of our customer’s networks due to the above Cisco Security Advisory Alert. It is our understanding from the manufacturer reports that unexpected behaviour or problems may occur approximately 18 months following activation /  ongoing operation.

Nowcomm would like to reassure our customers that any and all concerns will be dealt with promptly, with as little to no disruption to their operations as possible. Nowcomm engineering is working closely with Cisco to ensure that business remains “as usual” for all of our clients. Nowcomm is on the alert that should a higher than expected level of failures be identified across the UK market in general, then Cisco will ensure a higher than average availability of authorised replacement spares for those customers protected by a Nowcomm support or managed services contract.
