Asterisk VoIP Communications Engine on Azure

Deploy the current Asterisk LTS release on Microsoft Azure in minutes, configured the way telephony developers actually start projects. PJSIP endpoints are templated, the ARI REST interface and AMI are enabled and secured, a clean dialplan skeleton is already in place, and toll fraud protections are enabled before the first packet arrives. Built for developers, integrators and VoIP engineers creating IVRs, custom call flows, CTI integrations and communications applications who want the Asterisk engine without a GUI and without spending a day compiling and hardening the platform.

What You Get Out of the Box

• Current Asterisk LTS release installed from official sources.
• chan_pjsip configured as the standard channel driver, with commented endpoint, authentication and AOR templates that make adding SIP trunks or endpoints straightforward.
• A structured dialplan skeleton with separate contexts for internal, inbound and outbound traffic, using deny-by-default routing to reduce the risk of accidental toll fraud.

Common Use Cases

• Custom IVRs and Call Flows – Build menus, queues, time conditions and application logic using the Asterisk dialplan or ARI.
• Communications Applications – Develop Stasis applications using ARI with Python, Node.js, Go or any language supporting REST and WebSockets.
• CTI and CRM Integration – Originate, monitor and control calls from business applications using AMI and ARI.
• SIP Trunk Termination and Testing – Validate carrier SIP trunks and perform interoperability testing in a controlled environment.
• Learning and Certification – Study and experiment with a clean Asterisk installation without GUI abstractions.

Sizing Guidance

SIP signalling requires relatively few resources, while media processing, transcoding, recording and conferencing are CPU-intensive workloads.

• Development, testing and small deployments: Standard_B2s (2 vCPU, 4 GB RAM)
• Production deployments with recording or light transcoding: Standard_D2s_v5 (2 vCPU, 8 GB RAM)
• Higher concurrent call volumes, transcoding or media-intensive workloads: Standard_D4s_v5 (4 vCPU, 16 GB RAM), scaling to Standard_D8s_v5 for large conferencing deployments.
