PRI Replacement
Replacing PRI circuits? Preserve capacity, routing and resiliency while modernizing the architecture.
PRI environments often support PBXs, contact centers, fax, DID ranges and site-specific failover. Muse Mobility helps businesses determine whether the right replacement is SIP, UCaaS, Teams Voice, cloud calling or a hybrid design.
PRI Alternatives
Choose the replacement architecture deliberately.
Carrier SIP can preserve an existing PBX, while UCaaS or Teams Voice can modernize user calling. Some organizations need both, especially during phased migrations.
Replace PRI with IP-based PSTN connectivity while retaining the calling platform.
Move user voice features and PSTN access into a cloud platform.
Integrate PSTN calling with Microsoft Teams through an appropriate carrier model.
Separate legacy, contact-center and user-calling workloads during transition.
Cutover Planning
Capacity is only one migration variable.
A successful PRI replacement accounts for numbers, routing, hunt groups, toll-free, contact center, fax, emergency calling, network readiness and rollback.
Understand busy-hour usage and concurrent call requirements.
Reconcile DID ranges and service records.
Validate QoS, bandwidth, redundancy and edge configuration.
Verify inbound, outbound, E911, toll-free and failure scenarios.
Questions
What to know before you move.
What replaces a PRI?
Common alternatives include SIP trunking, UCaaS, Microsoft Teams Voice and other cloud calling services.
Can I keep my existing PBX when replacing PRI?
Often yes. SIP trunking may allow an organization to retain a compatible PBX while replacing TDM carrier connectivity.
