VoIP technology offers 911 service which differs from the traditional 911 services on landlines. VOIP company maintains your physical address in their system. 911 emergency calls are routed to a national call centre where callers are asked to confirm the physical address on file before being transferred to the closest emergency access point. This process will take more time than calling from a traditional landline where the location is already known.
