Is it possible to programmatically configure SIP trunk registration details across multiple Genesys Cloud organizations using the Platform API within a Premium AppFoundry integration? We are attempting to automate the deployment of telephony resources for new client tenants. The workflow involves creating the SIP trunk via POST /api/v2/telephony/sip/trunks and immediately updating the registration settings via PATCH /api/v2/telephony/sip/trunks/{trunkId}. While the initial creation succeeds, the subsequent patch request consistently returns a 403 Forbidden error, specifically citing insufficient permissions for the telephony:trunk:modify scope, despite the OAuth token possessing the required admin privileges. We have verified that the integration user holds the Site Administrator role in all target organizations. This behavior suggests a potential scoping issue or a delay in permission propagation during multi-org setup. Has anyone successfully implemented automated SIP trunk configuration in this context, or are there specific API sequence requirements we are missing?
