Hi everyone, We are planning to deploy Vapi on-prem in our AWS account using the AWS Marketplace installer and would like some guidance from anyone who has successfully hosted it. Specifically, we’re looking for: Required AWS resources — EC2 instance types (CPU/GPU), storage, VPC setup, Nitro enclave requirements, and any other infrastructure considerations. Deployment experience — tips or gotchas when using the Marketplace AMI or containerized deployment. Licensing / Plan requirements — is an Enterprise plan required for on-prem deployment? Inbound SIP trunks — we need to set up inbound PSTN/SIP routing, so any guidance on ports, NAT, or any other requirements would be helpful. External API calls — can the deployment be fully isolated in our AWS account, or are there mandatory calls to Vapi’s cloud? We’re okay with external APIs only for STT/TTS / transcription. Any shared experience, architecture examples, or links to successful deployments would be greatly appreciated.
