Add 10 Direct Inward Dialing, or DID, numbers to a FortiVoice call-trunk environment while including E911 service for a 5-year term. DID numbers give an organization individual inbound telephone numbers that can be assigned for calling workflows where separate public numbers are required. The pack quantity is fixed at 10 numbers, making it suitable when a single added number is insufficient but a larger trunk allocation is unnecessary. Fortinet FC1-10-VCSTR-1403-02-60 combines the number allocation and E911 service in one call-trunk service pack. Its five-year term is a material selection point for organizations planning multi-year voice service continuity. The service is focused on inbound numbering capacity and emergency-service support rather than on physical telephony hardware, so it does not add handsets, gateways, or a voice appliance. Use this pack when extending a FortiVoice deployment with additional DID coverage for departments, reception queues, remote staff, or public-facing contact points. Confirm that the number quantity, five-year service term, and E911 requirement match the intended voice configuration. The defining characteristics of this option are its 10-number allocation, included E911 service, and fixed five-year duration.
