Amazon Chime SDK SIP media applications availability change
After careful consideration, we decided to close Amazon Chime SDK SIP media applications to new customers starting October 29, 2026. To use the SIP media applications, sign up before that date. If you are an existing customer, you can continue using the service as usual.
We recommend that you migrate your PSTN Audio applications to Amazon Connect Customer. Build any new telephony workloads there too. Amazon Connect Customer offers the same core features as PSTN Audio. It also adds more advanced features for interactive voice response (IVR) design, managed compliance, and agentic AI customer engagement. Amazon Connect Customer is a purpose-built agentic AI solution. With it, you can design personalized customer experiences at enterprise scale. It provides visual no-code flow design and built-in carrier-grade telephony. You also get real-time analytics and AI features such as agentic voice and agent assist. You pay per use, with no minimum commitments.
Migration plan
You can migrate most telephony workloads from Amazon Chime SDK PSTN Audio to Amazon Connect Customer. It takes some careful planning. Amazon Connect Customer does not replace every PSTN Audio capability. But its flow-based design can handle all core use cases. This guide maps out a migration path. It covers architecture mapping, action-to-block translation, and an approach for each use case.
