Voice service will be cut over to a newly acquired group of session border controllers at 11 PM and will remain in service on the new equipment until 11PM Monday February 6th. This maintenance is necessary to allow for testing of the new equipment under full load while minimizing service impact to customers.

Immediately after traffic is cut over a full test plan will be carried out to verify all services are operating as designed on the new equipment and in the case of any failures all traffic can be rapidly rolled back to the stable production environment.
