AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
If you are an AWS Free Tier customer with a free plan, you are eligible to subscribe to this offer. You can use free credits to cover the cost of eligible AWS infrastructure. See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.
You pay by the hour for the EC2 instance you run this software on. Pricing is not organized into feature tiers. Instead, each dimension maps to a specific AWS instance type, so your rate depends on the compute size you choose. Small burstable options like t3.nano, t3.micro, and t2.medium suit light testing. General-purpose m4 and m5 families, compute-optimized c4, c5, c6a, c6i, c6id, and c6in families, memory-optimized r5, and bare-metal or high-performance hpc options serve larger workloads. Rates scale with instance capacity. You stop paying when you stop the instance.
Top-of-mind questions for buyers
What does the hourly rate cover, and what is billed separately by AWS?
The hourly rate covers the FreeSWITCH software image running on your chosen EC2 instance type. The underlying compute is bundled into the rate you pick. AWS bills separately for resources like storage volumes, data transfer, and any elastic IPs, which are not part of this software charge.
Am I charged when the instance is stopped rather than running?
Software charges meter running instance-hours only. When you stop the instance, the hourly software charge stops. AWS may still bill for attached storage that persists while the instance is stopped, but the FreeSWITCH software fee applies to running time. You stop paying the software rate when you stop the instance.
How do I choose which instance dimension to run, and can I change it later?
Each dimension maps to one EC2 instance type, so you pick based on the compute size your call volume needs. Light testing suits burstable t2 and t3 sizes; larger PBX or carrier-grade workloads suit bigger families. You can stop the instance and relaunch on a different type, which changes your hourly rate accordingly.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
