TAPI COMPATIBILITY AND CALL TEST RECORD
Yenra | Revised October 3, 2026
Guide: https://yenra.com/tapi/

Purpose: verify an exact supported Windows telephony combination and
separate line enumeration, call control, events, and two-way audio.
Use approved internal extensions and willing test participants.
Never use emergency or chargeable service numbers for this trial.
Keep passwords, tokens, full personal identifiers, and sensitive traces
out of shared notes. Protect diagnostic files under your support process.

INVENTORY
Application / version / architecture / required features:
Windows edition / build / architecture / local, remote, or virtual:
TSP vendor / exact version / approved installation source:
Phone-system release and update / control service:
Device / line / approved identity and association:
Vendor compatibility sources / versions / checked dates:
Support confirmation / unresolved constraints:
Saved configuration / supported rollback / maintenance window:
Approver / participants / planned impact:

TEST PLAN
Test date / time zone / clock synchronization checked:
Expected logical control path:
Actual audio endpoints and path:
Ordinary phone call without the app: expected / actual
Application enumerates correct line: expected / actual
Outgoing internal dial request: expected / actual / timestamp
Endpoint rings and answers: expected / actual / timestamp
Two-way speech: participant A result / participant B result
Disconnect: endpoint result / app idle indication / timestamp
Incoming indication and supported answer: expected / actual
Each separately supported feature (hold/transfer/etc.): result
Recording requires separate technical and legal arrangements.

FAILURE TRACE (COPY AS NEEDED)
Timestamp with zone / system / requested action / observation:
Returned error / protected evidence reference:
Boundary to investigate / owner / next vendor-approved step:
Do not infer a defective driver from one stale display observation.

CLOSEOUT
Result for each required feature:
Unresolved failure / operational consequence / support case:
Configuration restored or approved change retained:
Normal trace level restored / protected retention location:
Retest required / rollback outcome / owner:
