CoreDial:Offering VoIP, UC, SIP trunking and call center services.

CoreDial, LLC, headquartered in Plymouth Meeting, Pennsylvania, is a provider of both hosted PBX services and VoIP software, targeting small to mid-size businesses, and service providers in the Mid-Atlantic and other regions of the United States.

The company has grown through a focus on high quality, high value products and services, and has been named to the top 10 of the Philadelphia 100, a merit-based program sponsored in part by the Wharton Small Business Development Center, which ranks the fastest growing privately held companies in that area.

CoreDial provides communications solutions to three distinct markets: small business, enterprise, and, service providers. Their business offerings—targeted at organizations with between 5 and 499 end users—include virtual office, hosted PBX and VoIP, SIP trunking, and mobility solutions.

The company has also partnered with some notable hardware vendors—including Cisco Systems, Digium, EdgeMarc, and Polycom—to provide products that are complementary to their software solutions.

CoreDial’s software platform, called VoiceAxis, is targeted at both enterprise and service provider communities, with distinctive features that appeal to both markets.

These are grouped functionally, and divided into feature groups:

  • Auto Attendants (a customer portal, plus top level and sub-level auto attendants)
  • Call Management (auto attendant or live person answering, direct inward dialing, extension dialing, caller ID, voicemail, etc.)
  • Call Conferencing (3-way conference calls, conference bridge)
  • Music on Hold (royalty-free or customer-provided music on hold, commercials on hold, and commercials on hold by location or queue)
  • Reporting (call detail records, call volume graphs, call traffic by extension, and detailed accounting)
  • Origination and Termination Tracking (on-net calls, domestic origination/termination, international termination, SIP trunking, E911 support, and toll free numbers)

To support enterprises, the VoiceAxis 3.0 platform was designed as a software-as-a-service (SaaS) solution. This system is designed to connect multiple offices and workers seamlessly, globally, and cost-effectively. It includes the capability to custom-configure and integrate the software into many third-party technologies.

VoiceAxis runs on standard server platforms, with CoreDial providing software upgrades as long as the customer is using the system. Enterprise features include: a multi-tenant IP PBX cluster; support for multiple divisions or franchises; unlimited auto attendants; call center functions—including queuing and automatic call directors; unified communications; advanced call routing; call recording; find me/follow me; SIP trunking; and custom code and dial plan management.

The service provider feature set of the VoiceAxis solution enables both service providers and interconnects to sell, deliver, bill, and manage a number of IP services, including hosted PBX, VoIP, and SIP trunking. The VoiceAxis software controls a distributed, load-balanced Asterisk multi-cluster framework, where a cluster can provide for a specific class of service, or provide for a specific customer. The system enables service providers to set up and configure multiple resellers, each having access to a number of integrated systems, including proposal and service order management, service provisioning, customer self-service, and customer billing.

In addition, the software can be customized to meet specific business requirements, including integration with third-party technologies, letting carriers to deliver more innovative VoIP-based solutions. The system also includes an intuitive management interface, which includes multiple levels of access, and access to extensive network functions, including network and server resources, dial plans, calling features, routing paths, and billing. The cost of the platform includes all of the standard and premium calling features, thus simplifying the business operations and financial analysis.

VoiceAxis runs under RedHat Enterprise Linux, with either the Asterisk Business or Community Edition. The system also requires the most current versions of MySQL and PHP. The minimum configuration is four servers, with eight recommended for redundancy.
