Today, most businesses will agree that private communications is beginning to shift towards a cloud-based Unified Communications (UC) model. Private communications systems such as premise-based PBXs made sense when work was conducted at fixed locations and the worker was at the desktop. Today, business is conducted both face-to-face and remotely using a wide variety of voice, web and video conferencing tools as well as mobile devices like smartphones and tablets. Mobility is not really a choice any more—it’s a fact of business life.
The advantages of Unified Communications are somewhat more difficult to quantify than SIP trunking services, but many analysts agree that UC solutions can dramatically increase employee productivity and customer satisfaction. For example, analysts conservatively estimate that a unified communications infrastructure can save knowledge workers—that is, the majority of enterprise employees who create, collect and disseminate information on a daily basis-more than one hour per day in “lost” productivity, and as much as 50% higher when workers are mobile. That hour of productivity is regained because UC system’s help knowledge workers access and share information more easily, wherever their mobile office may be.
Traditionally, the desktop was king (hence the PBX was the core element of the service delivery), but today mobility in its many forms (smartphones and tablets and handheld devices running on either public, cellular or WiFi networks) has taken center stage. In fact, a Cohen Research Group survey found that 44% of enterprises have at least a quarter of their workforce operating solely using a mobile phone, and that 25% of IT decision makers believe desk phones will be displaced by mobile phones within two years.
For enterprises, it makes financial sense to centralize their communication applications and distribute these over private, public and hybrid cloud communication infrastructures. An enterprise can significantly improve productivity and save up to 40% by moving communications to network-based cloud solutions, which allows workers (and customers) to access communication applications from any location on any device.
Multi-PBX Integration & Integrated Dial Plan
As enterprises expand, they often struggle to maintain the same corporate connectedness in their newly acquired regional or branch office communications. Multivendor PBXs, costly PRI connections, disaggregated dialing plans and limited carrier provisioning all contribute to an inefficient communications infrastructure. With Sonus VoIP network solutions, enterprises can take back control of their communications with a single, flexible communication infrastructure.
Seamless, Integrated SIP Communication
The Sonus Branch Office/Multi-PBX Integration solution provides a seamless, integrated VoIP environment that enables multiple devices and signaling protocols to co-exist and communicate together: e.g., SIP PBXs, H.323 PBXs and even TDM PBXs. Our solution offers centralized policy and routing management for simplified dial plans, centralized billing and streamlined subscriber provisioning. With robust support for H.323 and SIP, the Sonus architecture represents a flexible migration platform from which enterprises can phase in more efficient IP-based services and network elements over time while leveraging their existing hardware investments.
Sonus Multi-PBX Integrated Dial Plan
- Immediate interworking of H.323 and SIP networks
- Centralized dial plans: no need to change dial plans and routing on every PBX in the network
- Centralized policy: one place to set time of day, least cost routing and other policy-based options
- Centralized SIP trunking: reduce monthly charges and improve disaster recovery with centralized, data center-based SIP trunking
- Elimination of long-distance charges for on-net calls between branches and customers using tail end hop off (TEHO)
- Centralized billing: one system that can analyze all billing call detail records (CDR)
