What happens to N3 Hosted Voice Services when the N3 catalogue service is unavailable?
A. Under failure of the primary circuit, N3 has a variety of resilience options depending upon site requirements and circuit type. CFUR (Call Forwarding Un Registered) is the most straightforward service, where upon a circuit failure all incoming calls are automatically diverted to a pre-arranged answering point, such as a mobile telephone or a standard telephone number. This service is a non cost option and can be arranged at a system level or even down to an individual extension number level. In addition, for certain larger capacity links, N3 Voice can provide a non cost option of hot standby between the primary and secondary N3 links in addition to the CFUR service outlined above. Finally there is a cost option known as Survivable Remote Site Telephony (SRST). This will provide basic call processing for local site and local PSTN calls under a primary circuit failure. Your N3 Voice specialist will be pleased to advise on all the options outlined above.
