Carrier sunsets are already underway
Traditional PRI and POTS services continue to be de-emphasized by major carriers, with aging infrastructure, shrinking support appetite, and higher costs becoming the norm.
PRI / POTS Replacement
A safer path off legacy phone lines before the carriers force the issue.
Organizations still relying on PRI or POTS know the problem is not theoretical anymore. Legacy voice services are getting harder to support, more expensive to maintain, and less aligned with the way modern communications environments work. BRCK helps teams migrate without creating unnecessary risk for users.
Why change now
Legacy lines are dying because the ecosystem around them is disappearing.
The issue is not just technology preference. Carriers are sunsetting old infrastructure, service models are deteriorating, and every year it gets harder to justify keeping business-critical voice services tied to circuits built for a different era.
SIP is more flexible
IP-based trunking scales more easily, supports modern UC platforms, and makes it far simpler to adapt as sites, users, and traffic patterns change.
The economics are improving
Many organizations moving from PRI or POTS to SIP reduce the overhead tied to fixed legacy circuits while gaining more flexibility in capacity planning.
User experience does not have to break
A well-managed migration keeps numbers, workflows, and end-user behavior as stable as possible while the underlying connectivity modernizes.
Cost and flexibility
PRI versus SIP is not just a line-item comparison.
SIP trunking often lowers the rigidity of legacy voice connectivity while creating more room for scaling, failover design, and integration with modern systems. The right migration plan looks at both cost and operational resilience.
PRI / POTS model
Fixed legacy circuits, slower change requests, aging infrastructure, and higher friction around adds, moves, and scale changes.
SIP trunking model
IP-based connectivity, flexible capacity, easier interoperability with modern platforms, and a cleaner path for migration and failover planning.
Migration process
Modernize the line type without destabilizing the business.
BRCK helps organizations assess existing circuits, plan cutovers, preserve user workflows, and reduce the operational risk that usually slows down migration projects.
Migration approach
1
Assess
Inventory circuits, numbers, devices, call paths, and any dependencies that could affect the migration plan.
2
Design
Map the target SIP environment, redundancy approach, user impact, and cutover sequencing.
3
Transition
Coordinate porting, testing, and activation so service moves with as little disruption as possible.
4
Stabilize
Validate traffic, support users, and retire legacy services once the new environment is operating cleanly.
Reduce migration risk
Talk to BRCK before your legacy voice environment turns into a forced emergency project.
We can help you compare options, stage the migration, and keep user experience stable while the underlying infrastructure changes.
