Routing Guardrail

If the user needs embedded softphone behavior in a web app, use Smart Embed (examples/smart-embed-postmessage-bridge.md).
If the user needs call records, analytics, or automation, use Phone REST API and webhooks (references/deprecations-and-migrations.md).
If the user needs click-to-dial/SMS launch from external UI, use URI schemes (
```
zoomphonecall://
```
,
```
zoomphonesms://
```
).
If the user mixes Zoom Phone and Contact Center, chain with ../contact-center/SKILL.md.

Common Lifecycle Pattern

Provision account prerequisites (Zoom Phone license, admin setup, SMS readiness).
Create OAuth app and scopes in Marketplace.
Choose integration surface:

Smart Embed (iframe + postMessage)
REST + webhooks
URI launch (
```
callto
```
,
```
tel
```
,
```
zoomphonecall
```
,
```
zoomphonesms
```
)

Capture real-time events (Smart Embed events and/or webhooks).
Persist call identifiers and correlate records (
```
call_id
```
,
```
call_history_uuid
```
,
```
call_element_id
```
).
Apply migration-safe data mapping (v1 -> v2 -> v3) and handle renamed fields.
Harden security (origin validation, webhook signature validation, least-privilege scopes).

High-Level Scenarios

CRM softphone pane using Smart Embed + contact search/match callbacks.
Click-to-call from account/contact table via
```
zp-make-call
```
.
Call disposition workflow using
```
zp-save-log-event
```
and custom notes page.
SMS engagement workflow with
```
zoomphonesms://
```
and
```
zp-sms-log-event
```
.
Real-time operational board driven by
```
phone.*
```
webhook events.
Call analytics migration from legacy call logs to call history/call elements.
Admin automation for user/auto-receptionist/call-queue call-handling settings.

See scenarios/high-level-scenarios.md for details.
