Legacy simulation
Interconnect lab
Browser-only adapters used by the original Meridian simulator. Never paste real supplier credentials here. Real DID/PSTN access is configured server-side in Provider pilot.
What still needs a vendor
CarrierAdapter
unprovisionedPSTN origination / termination
Attach a wholesale SIP trunk the way you attach a clearing provider — endpoint + digest. Until then the sandbox pipe answers.
SmsAggregator
readySMS / DLR
Meridian is the outbound pipe. The control plane (queue, LCR, DLR) stays yours.
NumberProvider
software-onlyDID inventory
Search, reserve, bundle, porting are live. Real E.164 stock needs a numbering relationship — paste their API key here.
StirShakenProvider
software-onlyPASSporT / Identity
Attestation logic runs. A trusted signature needs an STI-CA / SPC token, not a phone company.
EmergencyProvider
software-onlyPSAP routing
Civic address + DID binding is live. 911 → PSAP needs an emergency interconnect key.
Attach a pipe
This legacy probe runs in the browser and is suitable only for the internal echo endpoint. Use Provider pilot for server-side secrets, signed webhooks, number orders and calls.
Meridian
Meridian sandbox pipe
/api/v1/pipes/echo
Owned by you. Terminates into the in-preview virtual carrier. Replace with a licensed aggregator when you have their key.
