Why would someone still choose a PDF for 1.8 instead of upgrading? Here is the honest take:
That said, if you need AV1 video codecs or full QUIC support, you must upgrade. But for 90% of standard business VoIP needs (SIP trunks, queues, IVR, recording), FreeSWITCH 1.8 is still rock solid.
The 1.8 branch removed several deprecated modules that were present in 1.6. This required administrators migrating to the "2018 standard" to update their configuration files and replace outdated XML dialplan entries.
Modules are loaded at runtime to add functionality.
Several reputable VoIP training sites and community members have compiled PDF versions for FreeSWITCH 1.8:
