carrier grade media handling heritage built by the team that built freeswitch the relationship between freeswitch and signalwire the original creators of freeswitch founded signalwire to bring the same engineering rigor to the cloud two decades of telecom infrastructure experience live in every release today freeswitch is actively maintained by signalwire the same people who wrote it still shipping it about the team freeswitch today freeswitch on github freeswitch today from freeswitch to the control plane 2005 the origin anthony minessale and a small team set out to prove telecom could be software not the proprietary hardware vendors were charging fortunes for and locking customers out of freeswitch announced in january 2006 and now runs inside some of the largest telephony platforms in the world 2017 the platform in 2017 the same team founded signalwire and built a platform around the engine private modules a globally distributed network and a programmable control plane that freeswitch alone doesn t provide now today the open source engine stays free and community maintained the commercial platform funds that work and extends the engine with the scale redundancy and infrastructure teams would otherwise build from scratch two paths which fits your situation run freeswitch yourself when you require granular media control and custom c modules and are committed to an existing freeswitch solution and have dedicated resources to commit to maintaining on prem infrastructure get the source scale with signalwire you require granular media control and don t want to maintain the infrastructure and need to get to production fast and are upgrading or building a new product start building get a token id signalwire com source code github com docs signalwire com docs community signalwire community editions three ways to run freeswitch from the free community engine to a fully managed cloud the same team stands behind all three free self hosted freeswitch open source the community engine pl 2 0 community support you run it github repo paid self hosted freeswitch advantage the enterprise branch commercial modules g 729a amd founder level support you run it talk to us paid cloud hosted signalwire platform the programmable cloud programmable layer around freeswitch media engines commercial grade and built to scale runs in optimized signalwire cloud start building faq frequently asked questions what people ask about freeswitch from licensing to how it powers signalwire is freeswitch really free yes freeswitch is open source under the mpl license you can download modify and run it in production at no cost a free signalwire account is required to access packages and downloads what is the relationship between freeswitch and signalwire signalwire was founded by the original creators of freeswitch and is the primary maintainer of the project today signalwire s cloud platform runs on the same core engine can i migrate from self hosted freeswitch to signalwire yes because signalwire is built on the same engine dialplans and concepts migrating workloads from self hosted freeswitch to signalwire s managed cloud is a natural path where do i get
