Nexvoice supports standard telephony style functions and offers a suite of standard office-style features that are implemented within the Nexvoice network independent of whether the customer's ATA is plugged in or not. Designed to function as a standalone service to allow seamless integration with currently installed telephone systems, subscribers are allocated an NVSN (Nexvoice Service Number) that enables subscribers to receive and make on-network and off-network calls.

Nexvoice provides all aspects related to Call Handling, Call Management and remote Customer Control, Subscriber Management & Support as well as Automated Subscriber Provisioning.

Nexvoice services deliver standard telephone calling functions between the PSTN and IP-endpoints with toll-quality voice and a suite of call management features. Nexvoice is currently released with a standard Nexvoice 1.0 feature set, including Legal interception functionality and support of Emergency Services.
