ENTERPRISE SERVICES

With services like Centrex and Virtual Office, business customers can communicate more efficiently while retaining their existing technology and phone numbers. Using a high-speed Internet connection, users are able to customize features and control settings online and in real time, from anywhere in the world. Dramatically lower calling costs, simplified billing and a wide array of business-friendly features are the key to the success of VoIP enterprise telephony services.

Who is it for?

	Small businesses serving customers with long-distance communication needs
	Enterprises whose customer base and/or staff includes a substantial traveling sales force
	Large-sized corporations with geographically dispersed locations
	Any mid-or large-sized company without sufficient reception staff to take personal messages for employees
	Telecom companies interested in providing telephone connectivity to remote offices/communities
	Companies competing with local telecoms by offering enhanced 3rd generation services (Centrex, IP PBX, follow-me, mobility, etc.)

How does it work?

	The caller dials the desired local or long-distance number directly. The call is then sent over the company’s high-speed Internet connection via a VoIP gateway or the company’s existing PBX.
	When dialing a number within the same enterprise, abbreviated dialing is also available.
	Once the call is completed, it is charged to the company’s account balance.
	Users (administrators and/or individual employees) may log in to the account self-provisioning interface at any time to access call history (CDRs), payment information, language options, and many other features.

Solution components

The core elements of VoIP-based enterprise services include:

	A VoIP Gateway that supports RADIUS/AAA (CISCO, Quintum, etc.); this plays the role of an interface for the originated call from the PSTN (caller’s phone) to the IP network (Internet), and includes an IVR (Interactive Voice Response) server that provides voice prompts describing the account balance and minutes available for the call
	PortaBilling100 Software, a real-time billing and customer care platform that keeps track of calls and corresponding charges; redundant system architecture (dual database) is already incorporated in the basic version
	PortaSIP software, a call control software package based on the Session Initiation Protocol (SIP), providing a full array of call routing capabilities as well as a solution to the NAT traversal problem
	PortaUM (Unified Messaging System) for handling voice, fax, and regular e-mail messages as objects in a single mailbox, which users can access via a web interface or by telephone
	Compatible end-user hardware (IP telephones, integrated access devices, VoIP gateways with FX ports, etc.)
