[Freeswitch-users] Setup Verto in Local to Replace SIP

Hi, I am not sure if this approach is still being used these days, but I'd like to know if there is any guide out there to set up Verto in Local (No SSL certificates required). My use case is that we don't want to involve with the Internet yet we still want the call to be established via Verto rather than SIP since SIP is not supported by the latest version of Android out of the box. Any help would be appreciated. Best regards, Chhatra Chhorm
