Your PBX. Our Network. Modern Voice.
DIGI-SIP connects your existing business phone system to modern IP voice services—giving you the flexibility, scalability and reliability to modernize communications without starting over.
Modernize Your Business Voice Without Replacing Everything.
DIGI-SIP connects your existing phone system to the modern IP voice network, giving businesses a flexible, scalable alternative to traditional phone lines and legacy voice services.
Keep the PBX and phone infrastructure that still works while moving your voice services to SIP. With pooled sessions, flexible routing, failover options, number management and centralized service control, DIGI-SIP provides a foundation for modern business communications without forcing an unnecessary rip-and-replace.
Built for Complex Voice Environments
DIGI-SIP is particularly well suited for organizations with:
Multiple offices or locations
Existing PBX infrastructure
High volumes of inbound or outbound calling
Distributed call centers
Legacy PRI or TDM environments
UCaaS migration projects
Acquisition or expansion requirements
Business continuity requirements
Remote or hybrid workforces
One Voice Platform. Multiple Locations.
DIGI-SIP can provide a common voice foundation across your organization.
Instead of managing separate voice services at every location, organizations can use shared capacity and centralized routing to create a more consistent communications environment.
This approach can also help reduce unused capacity and simplify administration. The Lumen model used pooled sessions specifically to share capacity across locations and included failover capabilities.
Keep what works. Modernize what doesn't.
DIGI-SIP is designed for organizations that want to modernize their voice infrastructure while protecting existing investments in PBX equipment and business phone systems.
Flexible Capacity
Pool voice sessions across locations so capacity can be used where it's needed instead of dedicating resources to individual locations.
Built for Business Continuity
Configure multiple trunks and routing options to help maintain voice service when a primary connection or route is unavailable.
Works With Your Existing PBX
DIGI-SIP can connect compatible existing PBX environments to IP-based voice services, providing a practical path from legacy telephony to modern communications.
Simplified Management
Manage telephone numbers, routing and service configurations through centralized tools rather than managing disconnected voice services across locations.
Scale With Your Business
Add locations, numbers and voice capacity as your business changes without rebuilding your entire communications infrastructure.
Local, Long-Distance & Toll-Free Calling
Support the calling services your organization needs through a unified SIP-based solution.
