Aircall vs FreeSWITCH
Fit:
Migration notes
FreeSWITCH offers routing, IVR, recording and queue/call-center primitives for a custom voice system. Aircall supplies a shared workspace, CRM integrations and analytics; those workflows need other applications or development. Retain/export required recordings and reporting separately; no verified Aircall migration importer. Carrier/number transfer needs provider coordination.

What you may give up
- Commercial mod_com_amd answering-machine detection requires per-channel licences; module is outside the public source tree.
- Commercial mod_com_g729 G.729A encoding/decoding requires per-channel licences; passthrough is distinct from transcoding.
- Official prebuilt packages/downloads require a free SignalWire account; public source remains available on GitHub.
- Phone numbers, SIP/PSTN trunks, hosting and call usage can incur separate charges.
- Building an agent desktop, CRM workflows, dashboards and production operations requires additional software and engineering.
Tier C: Core public source is OSI MPL-1.1 per current HEAD LICENSE, with additional component notices. Tier C reflects same-vendor paid ordinary voice functionality in separately distributed proprietary AMD and G.729 modules, not carrier/service charges. Advantage/Pro builds and support are commercial offerings. First-party SignalWire Platform adds private modules and managed APIs; hostedOffer does not imply application or source parity. Marketing license card differs from repository LICENSE; source evidence controls this record. License source
What running it takes
-
- FreeSWITCH binary and selected module/sound packages
Hover or focus an icon for its name. Dashed means not established; struck through means no; grouped icons are alternatives.
Telephony server framework, not turnkey contact-center desktop. Native packages or source build. Embedded SQLite default; PostgreSQL or MariaDB core database alternatives require matching module and DSN. SIP registration/queue modules can use their own SQLite/ODBC configuration. Infrastructure and staff time are not priced here; this page does not compare total cost.
