Trying to understand why our AppFoundry integration throws a 403 Forbidden when initiating SIP trunk registration after an OAuth token refresh.
Background
We are deploying a multi-org integration using Platform API v2.0. The initial token acquisition works fine, allowing successful SIP registration.
Issue
Upon token rotation, the PUT /api/v2/architect/sip/trunks endpoint returns a 403. The scope includes telephony:sip:write.
Troubleshooting
- Verified token validity via external debugger.
- Confirmed permissions match previous successful calls.
- No rate limiting observed in headers.
