Presentation Testing
Verify the CLI received at the destination matches the CLI sent.
CLI Verification
Prove your caller ID arrives the way you sent it.
CLI verification and route testing that shows how caller identity is actually presented at the destination — so you can protect answer rates, brand trust and route quality.
Overview
Caller identity is a quality metric
When caller ID is lost, altered or refiled somewhere along a route, the damage is real: answer rates fall, callbacks fail, and legitimate traffic starts to look like spam. Yet most senders have no visibility into how their CLI actually lands.
Vireon's CLI verification capability tests presentation end-to-end: calls are placed across routes to real destinations and the received caller ID is compared with what was sent. The result is evidence — per route, per destination — of where CLI survives and where it doesn't.
Carriers and enterprises use this to audit suppliers, validate premium route claims, and keep outbound programmes performing.

Common Questions
Frequently asked questions
Who uses CLI verification?
Carriers auditing their supplier routes, wholesale buyers validating premium-route claims, and enterprises protecting outbound answer rates.
How are tests performed?
Test calls are placed over the routes in question to destination test points, and received presentation is compared against what was sent.
Can testing run continuously?
Yes — scheduled programmes monitor CLI behaviour over time so degradation is caught when it starts.
Does this relate to STIR/SHAKEN or branded calling?
Ecosystem authentication frameworks vary by country and evolve quickly. Talk to our team about what applies to your destinations and how verification fits alongside it.
