VPN Business Trunking allows you to introduce low-opex IMS-based private branch exchange connections to enterprises without sacrificing any voice revenue.
The Virtual Private Network (VPN) Business Trunking connects private branch exchanges (PBXs) to the public IP Multimedia Core Network Subsystem (IMS) network, while providing the means to identify if traffic is data or voice.
In this way, our Business Trunking enables opex savings in the IP infrastructure by allowing voice and data on the same connection. At the same time, it supports existing voice channel oriented business models and enables full control of call capacity, according to familiar Service Level Agreements.
VPN Business Trunking performs a number of valuable tasks to secure business for you as well as for connected companies. It validates PBX originating calls to acquire a valid calling party identity for billing purposes. It performs call admission control on the number of parallel voice calls over an IP trunk to safeguard your income as well as call capacity for the subscribed enterprises.
VPN Business Trunking allows voice and data to be handled on the same connection, drastically reducing costs.
The Session Initiation Protocol-compliant connectivity opens up possibilities to deploy multimedia enriched communication PBX features outside company boundaries.
VPN Business Trunking allows you to prolong familiar business models on PBX connectivity, based on the capacity of a number of parallel voice channels, while taking advantage of the opex reductions provided by introducing IMS.
Unlike the situation with individual IMS users, VPN Business Trunking does not require provisioning of each user behind a PBX, eliminating any impact on network provisioning through changes within the company.
Fully redundant configurations and rerouting solutions to cover for PBX failures and failures in the link to connected PBXs secures continued operation and therefore user satisfaction and revenue.
