Amazon Nova Sonic SIP integrations
Integrating Amazon Nova Sonic with Session Initiation Protocol (SIP) infrastructure requires an software server that serves as an middleman layer. This server manages each SIP signaling and Actual-time Transport Protocol (RTP) media streams, whereas sustaining the connection to the Nova Sonic bidirectional streaming API. The server bridges your present telephony infrastructure with Nova Sonic to deal with name session administration and audio routing between each techniques.
There are two pattern implementations: a Java-based SIP gateway utilizing the mjSIP stack and AWS SDK for Java, and a JavaScript SIP server utilizing Node.js with SIP.js and the AWS SDK for JavaScript. Each samples display the identical core structure with language-specific implementations.
The core parts embody a SIP stack for name management signaling, an RTP handler for audio stream processing, and an Amazon Nova Sonic shopper that maintains persistent connections to Amazon Bedrock. When an inbound name arrives, the SIP Server solutions by way of SIP, establishes RTP media periods, and creates a corresponding Sonic streaming session. Audio flows bidirectionally:
- RTP packets from the caller are decoded, transformed to the suitable audio format, and streamed to Nova Sonic
- The Nova Sonic audio responses are encoded and transmitted again by way of RTP
For deployment, you’ll be able to run the SIP Servers on Amazon Elastic Compute Cloud (Amazon EC2) situations with correct safety group configuration for SIP signaling (port 5060) and RTP media streams (usually ports 10000-20000), or deploy containerized utilizing Amazon Elastic Container Service (Amazon ECS) with host networking mode to entry the required UDP port ranges. Each approaches:
- Require IAM permissions for Amazon Bedrock entry and correct credential administration.
- Assist seamless integration with PBX techniques, VoIP suppliers (like Vonage), or conventional telephony networks if you configure your present telephony infrastructure to route calls to the gateway’s public endpoint
Integrations with telephony suppliers
Cloud telephony suppliers like Vonage, Twilio, Genesys, and Amazon Join provide managed voice companies that deal with the complexity of conventional telephony infrastructure by way of easy APIs. In contrast to direct SIP integration, these suppliers summary the underlying protocols and provide options like international cellphone quantity provisioning, automated failover, name analytics, and compliance capabilities.
Vonage
Vonage is a cloud communications platform that gives voice, messaging, and video APIs for companies. An Amazon Nova Sonic integration with Vonage was introduced in July 2025, offering a direct path to attach cellphone calls to conversational AI by way of the Vonage Voice API. With this integration companies can deploy real-time voice brokers throughout telephony channels with out managing complicated telephony infrastructure, as Vonage handles name routing, audio streaming, and protocol translation. The combination works by configuring Vonage webhooks that set off when calls are obtained or initiated. Your software server receives these webhook occasions, establishes a Nova Sonic streaming session, and creates a bidirectional audio bridge between the Vonage name and Nova Sonic. Vonage manages the telephony complexities together with codec conversion and community transport, whereas your server handles the AI dialog circulate and connects to what you are promoting techniques and knowledge sources.
