Legacy-to-SIP migration
BRCK helps Avaya environments move from PRI, analog, or outdated carrier models into SIP trunking with a practical migration plan and fewer operational surprises.

BRCK for Avaya Migrations and SIP Trunking
BRCK helps organizations modernize Avaya environments with SIP trunking, carrier replacement, and migration support that bridges legacy voice systems to a more resilient future state.
Common Avaya transition paths
Keep Avaya in place but replace legacy circuits with SIP trunking.
Move from Avaya toward Teams, Webex, or another UC platform in phases.
Improve business continuity before a full voice-platform migration is complete.
Why BRCK for Avaya
Modernize the carrier side first, then modernize the rest on your terms.
Many organizations are not ready to rip out Avaya in one motion. BRCK helps create a cleaner interim state by replacing legacy trunking with SIP, supporting number continuity, and giving the business room to plan the next stage without treating voice as a crisis project.
What this solves
Reduce dependency on aging PRI and analog services.
Create a more flexible routing model around an existing Avaya estate.
Make future migration work easier by cleaning up numbers and carrier relationships now.
Migration architecture
How BRCK helps bridge Avaya to a more modern voice stack
Users can stay on Avaya while BRCK replaces legacy trunking with SIP connectivity, improves routing resilience, and prepares the organization for a cleaner next-step migration when the business is ready.
Avaya modernization flow
1
Existing Avaya users
Employees continue working on familiar phones, extensions, and call flows during the transition period.
2
Avaya platform
The current PBX or call processing layer stays in place while the carrier side is modernized.
3
BRCK SIP replacement
BRCK replaces legacy trunking with SIP, provides DIDs, and supports failover and number continuity planning.
4
Future-state voice
The business can later migrate to cloud UC, new PBX architecture, or hybrid voice models with less carrier friction.
Migration support
A practical path off legacy carrier infrastructure.
BRCK supports the parts of Avaya modernization that often create risk: carrier replacement, staged cutovers, number handling, and keeping the business reachable through the transition.
Carrier replacement
If your Avaya system still works but your current voice provider does not, BRCK can serve as the replacement trunk provider while you modernize on your own timeline.
Phased modernization
Support hybrid states where some sites, call flows, or business units remain on legacy infrastructure while others move toward newer UC or cloud environments.
Number continuity
Keep core business numbers intact during migration, including main lines, branch numbers, and routing logic that matters to day-to-day operations.
Business continuity planning
Use SIP-based routing and failover design to improve resilience compared with aging circuits and harder-to-replace legacy voice services.
Human support during cutovers
Large voice transitions are rarely clean by accident. BRCK provides hands-on coordination for the details that can derail a migration.
