From discovery to managed continuity.
Six services, one lifecycle. Every engagement starts at Discovery, because you cannot responsibly replace what you have not identified, and ends with an environment that stays documented, monitored and visible.
Find every line and what it touches.
Bills, carrier records, notices, site walk-downs and endpoint tracing, assembled into one inventory of lines, endpoints and dependencies. Unknown line purpose is expected; that's what Discovery is for.
Determine what must remain true.
Per line: what it supports, what's changing at the carrier, how urgent it is, which code and acceptance requirements apply, and which stakeholders must be involved before anything moves.
A controlled cutover, not a swap.
The appropriate path chosen per line (remove, migrate native, Cline, or endpoint upgrade), coordinated across vendors, monitoring providers and the carrier, with end-to-end testing before legacy service is released.
Managed connectivity for critical legacy endpoints.
When preserving a POTS-like interface is the appropriate migration path, Cline provides managed connectivity for the endpoint: installed, tested, documented and monitored as a service. It is one answer within the lifecycle, never the starting assumption.
Migrated is not the same as finished.
The migrated environment stays documented and visible: what is working, what is in trouble, what was tested and when, including carrier activity that could affect it again.
The whole estate, one program.
For multi-site organizations: one inventory, one exposure model, phased rollout waves and site-level reporting, including the lines you have not migrated yet.
Multi-site portfolios →How an engagement starts.
One or a few properties, an active notice, approaching inspection, outage or urgent migration.
For Discovery and planned migrations.
For multi-site prospects, routed to enterprise discovery.
No generic product demo. We'll talk about your lines, properties and deadline.

An address is enough. You don't need to know every phone number yet.
