Small and Medium-sized Enterprises (SMEs) are increasingly operating at least one remote business site. Although many small businesses have extended their data network to the branch offices, voice services at these locations often remain basic. Not to mention, the cost of maintaining several networks (the IP, LAN, WAN and PSTN) is substantial considering the cost of upgrades, maintenance, support and human resources required to perform these mandatory tasks.

The Dial-Centrex hosted IP PBX solution can provide even the smallest of businesses with the productivity benefits and cost savings advantages attributed to reduced long distance expenses without incurring the cost of ownership/maintenance of a high end PBX.  There is no hardware or software to buy, install, maintain or upgrade so it has enormous cost advantages over other approaches. It provides the SME or SOHO (small office home office) with a VoIP business phone solution that includes all the features found in a “corporate” PBX phone system such as integrated voicemail, auto attendant/IVR, find me/follow me and failover support.

The Dial-Centrex virtual office PBX for small businesses is 100% SIP based. It delivers calls over IP through the customer’s converged networks (voice and data).Fully interoperable with the industries leading SIP devices, VoIP gateways and IP telephony equipment; this hosted application easily integrates with legacy TDM and IP networks.  Dial-Centrex is designed to work as an ASP model hosted IP PBX in a SOHO or a multi-branch enterprise through the WAN or Internet.

The Ideal Hosted Solution for Service Providers
The Dial-Centrex hosted VoIP PBX solution is located at the Internet Telephony Service Provider’s (ITSP’s), Internet Service Provider’s (ISP’s), Competitive Local Exchange Carrier’s (CLEC’s) or NEXTGEN operators premises.  Easy to manage and feature rich, the small business phone system enables service providers to move past commoditized bandwidth and minutes of use. Service providers can reap additional revenue and become the critical communications partner of their small and medium-sized enterprise clients.
