Why California Businesses Are Abandoning Legacy PBX
Traditional on-premises PBX systems are expensive to maintain, difficult to scale, and incapable of supporting today's hybrid workforce. The average legacy PBX requires $15,000–$50,000 in maintenance and upgrades every 3–5 years, and adds zero value to remote workers who have become a permanent fixture of the California business landscape.
Modern UCaaS platforms deliver all PBX functionality plus advanced collaboration tools — from a cloud platform with 99.999% uptime SLA, accessible from any device, anywhere in the world. NexCore Systems designs, deploys, and manages UCaaS solutions for organizations from 10 to 5,000+ users.
Our VoIP & UCaaS Services
Cloud PBX & Business Phone Systems
We implement and manage leading cloud PBX platforms including RingCentral MVP, Zoom Phone, 8x8 X Series, and Microsoft Teams Phone System. Every implementation includes number porting from your existing carrier, custom auto-attendant configuration, hunt groups, call queues, voicemail-to-email, and integration with your CRM platform.
Microsoft Teams Direct Routing
For organizations already using Microsoft 365, adding Teams Phone with Direct Routing converts your existing Teams environment into a full enterprise PBX. NexCore handles Direct Routing infrastructure, SBC configuration, and carrier connectivity to deliver PSTN calling through Teams at a lower cost than competing solutions.
Contact Center as a Service (CCaaS)
Transform your customer experience with cloud-based contact center solutions featuring intelligent routing, real-time supervisor dashboards, call recording, quality management, workforce management, and CRM screen pop integration. We implement Genesys Cloud, NICE CXone, and RingCentral Contact Center for organizations requiring sophisticated customer interaction management.
SIP Trunking
If you have an existing on-premises PBX that still has useful life remaining, SIP trunking replaces costly ISDN PRI circuits with cost-effective IP-based voice services. NexCore provisions SIP trunks from multiple carrier partners, implements redundant routing, and configures failover to cellular to ensure business continuity.
