## Session Summary

Explored and tested the VoIP provisioning workflow integrating PacketDial (NetSapiens PBX) with Yealink YMCS (phone management). The goal was to design a general-purpose provisioning script that creates SIP users in PacketDial and provisions them onto physical Yealink phones.

Successfully verified both PacketDial and YMCS skills are functional and authenticated correctly. Created a comprehensive provisioning plan with test cases to resolve critical unknowns. Executed Test Case 1 (PacketDial user creation and password management) successfully, creating test extension 100 in the vwp.91912.service domain. Test Case 2 (YMCS SIP account provisioning) hit a blocker on the `sipServer1` field format - the YMCS API returns HTTP 412 "Parameter error" regardless of variations attempted (hostname, hostname:port, with/without additional fields).

The session produced a detailed implementation plan, documented both systems' capabilities, identified the integration gap between the two platforms, and established that additional research or Yealink support contact is needed to resolve the YMCS schema issue before end-to-end provisioning can be completed.

## Key Decisions

- **General-purpose workflow over one-off testing** - Chose to design a reusable provisioning script (`provision-voip-user.sh`) rather than just manually testing one phone, enabling future automation and integration with onboarding workflows.

- **Test password approach** - Selected "set a known test password" for initial testing rather than attempting auto-generated passwords or vault-managed passwords, simplifying the proof-of-concept phase.

- **Incremental test cases** - Structured the plan with three distinct test cases (PacketDial password, YMCS schema, end-to-end verification) rather than attempting full integration immediately, allowing each blocker to be identified and resolved independently.

- **API field name exploration** - When `sip-password` field didn't visibly change account status, tried multiple variations (`password`, raw PUT endpoint) to determine the correct method, accepting that password verification may be hidden for security reasons.

- **Error-driven schema discovery** - When YMCS API documentation proved difficult to access, used the "try minimal schema and iterate on errors" approach to discover required fields, though this ultimately revealed a blocker requiring external documentation.

## Problems Encountered

**PacketDial SIP password verification unclear** - Set password via `update-user` with both `sip-password` and `password` fields (both returned 202 Accepted), but the `account-status` field remained "pwd reset" rather than changing to active/enabled. The password may be set correctly but not exposed via GET for security reasons, or the field name may be different.

**YMCS sipServer1 field format unknown** - All attempts to provision SIP account to YMCS failed with HTTP 412 error code 900444 on the `sipServer1` field. Tried multiple variations: bare hostname (`pbx.packetdial.com`), hostname with port (`pbx.packetdial.com:5060`), with additional common SIP fields (`sipServer1Port`, `transport`, `label`, `accountName`, `displayName`, `userName`, `authName`, `enable`). Error message consistently indicated "Parameter error, please refer to documentation related to interface parameters".

**YMCS API documentation access** - Official Yealink YMCS API documentation is in PDF format behind support portal. WebFetch attempts failed due to redirects and size limitations. The n8n community node repository (dszp/n8n-nodes-yealinkymcs) exists but TypeScript source files with field schemas were not accessible via direct GitHub raw URLs. Live OpenAPI endpoint at us.ymcs.yealink.com/manager/openApi failed to load properly.

## Configuration Changes

**Created:**
- `/Users/azcomputerguru/.claude/plans/sprightly-jumping-clarke.md` - Comprehensive provisioning workflow plan with architecture understanding, test cases, implementation strategy, and success criteria.

**Modified (PacketDial):**
- Created test user: extension 100 in domain `vwp.91912.service`
- User details: Test User, SIP username `100@vwp.91912.service`, voicemail PIN 92033433
- Attempted password set via multiple methods (verification pending)

**No changes to YMCS or physical devices** - Provisioning blocked at schema discovery phase.

## Pending / Incomplete Tasks

**Blocker: YMCS sipServer1 field format** - Need to determine the correct format and required fields for YMCS SIP account creation. Options:
1. Contact Yealink technical support with specific API v2 schema questions
2. Download and review the full YMCS API documentation PDF (access requires Yealink support portal login)
3. Find a working YMCS installation and inspect an existing SIP account configuration via API GET
4. Contact David Szpunar (dszp) - maintainer of the n8n-nodes-yealinkymcs package - for schema examples

**Verification needed: PacketDial password actually set** - Account status shows "pwd reset" but this may be cosmetic. Next step: attempt to register a softphone or the actual Yealink device using the credentials to verify password works, independent of YMCS API.

**Test Case 3 not started** - End-to-end phone registration verification cannot proceed until YMCS provisioning succeeds.

**Script implementation not started** - `provision-voip-user.sh` creation blocked until both test cases resolve successfully.

**Documentation pending:**
- SIP password management method for PacketDial (once verified)
- YMCS add-sipaccount schema (once discovered)
- End-to-end provisioning workflow examples
