As global connectivity increases, enterprise voice communications have grown ever more complex. The sheer number of technologies, channels, and enhanced features involved has turned enterprise business communications into its own specialized ecosystem, requiring not only technical expertise but also industry knowledge, brand awareness, and robust vendor management skills.

CBTS believes that simplification is overdue. The CBTS Universal SIP Toolkit is designed to consolidate enterprise SIP calling infrastructure and introduce speed and transparency for technology teams. With the Universal SIP toolkit, enterprises gain guaranteed access to the products, services, and connectivity they need to build a customized, fit-for-purpose, resilient voice system at the core of their modernized digital workplace.

Solving the pain points of modern enterprise SIP calling

Increasingly complex voice environments demand complete, long-term solutions. The Universal SIP Toolkit is built specifically to address the toughest challenges of large-scale, modern enterprise phone systems, namely:

Platform integration

Challenge: To achieve the necessary functionality, enterprises must adopt a suite of separate communication platforms. These are provided by different vendors and are not built to integrate, leading to overlaps, conflicts, and gaps.

Solution: The Universal SIP Toolkit is an interconnected, compatible ecosystem, backed by expert solution engineering from CBTS. CBTS leverages its experience to help you build a custom environment optimized to provide the features you need—whether your healthcare organization requires faxing, or your call center requires in-depth data analytics—and seamlessly unified across your enterprise.

Reliability

Challenge: SIP calling is reliant on network bandwidth for call quality and performance. Service can vary widely across regions, increasing the potential for failures as your organization grows. Interruptions and outages can create an inconsistent, frustrating experience for both employees and customers.

Solution: Expert SIP trunking leverages existing network infrastructure, including SD-WAN for distributed workforces, to optimize voice traffic for call quality and reliability. Moreover, CBTS supports you with robust continuity planning and disaster recovery strategies, including failover options for regional outages and backup resources in the event of a catastrophe. With interconnected, centralized telephony management, your business can maintain a consistent presence for both employees and customers.

Scalability

Challenge: Complex enterprise voice systems are challenging to expand due to regional variations in Internet and telephone providers. Even without geographical concerns, platforms may have varying license limits or seats or may create compatibility issues at certain scales. Add to that the simple logistics of adding more clients, desk sets, voice lines, phone numbers, and more, and scaling up can present significant hurdles—especially if your technology department is stretched thin or lacks expertise in SIP calling solutions.

Solution: The flexible technology core of the Universal SIP Toolkit, backed by CBTS engineering expertise, can accommodate enterprises of any size. Support from CBTS simplifies adding or changing users and services, and the Toolkit’s curated ecosystem ensures seamless integration. The adaptability of the Toolkit enables enterprises to match service levels to needs, making it easy to access assistance with designing, configuring, and deploying additions to the phone system. In addition, CBTS’s far-reaching vendor relationships pay dividends as you spin up satellite locations or empower remote workers.

Cost efficiency

Challenge: Assembling piecemeal communications solutions will likely lead to redundancies and overpayments. With limited ability to “mix and match” platform features and less transparency into their communications software ecosystem, most enterprises often find themselves duplicating functionality and paying full price for a solution that is far larger than they need. For example, the UCaaS solution your office already uses may include basic contact center functionality but lack one key feature that will force you to adopt an entirely separate CCaaS platform.

Solution: The Universal SIP Toolkit offers a holistic, streamlined alternative to ad hoc point solutions. Working alongside CBTS, your teams can build the ideal solution for your business needs from the wide range of functionality offered by CBTS partners. Complete visibility and extensive customization options ensure controlled costs and maximum value.
