Freeze one company, user, client path and symptom
Record company and office, user, product or license, direct number, shared-line roles, selected line and caller ID, native desktop, Chrome web, PWA, extension, iOS or Android path, operating system or browser, package owner, app-reported build, network, local and UTC time, direction, destination and first visible symptom. Redact credentials, precise location and unrelated participant data.
Separate sign-in failure, missing Phone surface, rejected setup, wrong caller ID, provider attempt routed elsewhere, no alert, silent ringtone, answer failure, answered call without audio, wrong device, poor media and missing quality evidence. Do not merge personal, shared-line, desk-phone, browser, mobile HD Calling and native-dialer results.
Prove assignment, line and destination before reinstalling
Confirm the exact Dialpad product or license, direct number, operator or agent membership, available line, selected caller ID and destination format. For a shared line, verify the user is an assigned operator or agent and distinguish that membership from a personal direct line. Record any guidance message or error exactly.
A sign-in, Phone icon, profile number or another successful destination does not prove the failing line, caller ID or destination is accepted. Preserve the original build and result before update, cache, sign-out or reinstall actions so a later success has a meaningful comparison.
Trace inbound routing, notification and the answering endpoint
For one controlled non-emergency inbound call, inspect personal and shared-line handling, forwarding, voicemail, Do Not Disturb, browser or operating-system notification permission, app notification choices, ringtone output and connected devices. Record the provider attempt, Dialpad target, app or browser notification, visible alert, audible output, answer action and final answering endpoint.
Chrome notifications outside the web-app tab require permission. A badge, history row, voicemail or successful answer on another device does not prove the affected client received an alert or produced an audible ringtone.
Compare the exact client build and network path
Record native desktop, Chrome web, PWA, extension, mobile or approved VDI path and the actual running build. Keep a passive update, required update, available download, automatic update and centrally managed deployment separate. If VDI is involved, retain the documented non-VDI reproduction boundary.
Compare one controlled call on one alternate network only after preserving the original result. Another-network success narrows the boundary but does not identify the original Wi-Fi, VPN, firewall, proxy, router, ISP or traffic inspection setting as the cause.
Separate device selection, test results, packets and perceived media
Record operating-system input and output plus Dialpad microphone, speaker or headset, ringtone output, notification volume, Bluetooth path and processing settings. A local audio test, WebRTC diagnostic or System Test is useful bounded evidence, but none proves line selection, PSTN routing, the remote endpoint or two-way media for the affected call.
For the affected call preserve both packet directions, codec, quality metrics where authorized, decoding and what each party heard. QoS server-side and client-side values, MOS, jitter, loss, latency or a network score are investigation signals rather than proof of one perceived outcome or root cause.
Correct one owner and preserve support evidence safely
Assign the first divergence to one owner: company, office, identity, product, license, direct or shared line, caller ID, destination, call handling, client path, build, notification, network, local device, signaling, media, emergency location or support. Change one controlled variable and repeat the same non-emergency number, line, client path, network and direction plus one unaffected control.
Collect only authorized System Test details, error reports, console errors, WebRTC diagnostics or mobile debug logs. Preserve timestamp and time zone, sanitize sensitive data and use the approved support channel. Keep submission, case, finding and verified restoration separate. Static and Dynamic E911, permission, location source, validated address, 933 result and mobile native-dialer behavior also remain distinct. No account, client, call, emergency outcome, metric, log or support response was inspected or tested.
