Mumble's server component, Murmur, allows anyone to run a server of their own for public or private use, free of charge. Murmur supports extensive user permission configuration using access control groups (ACLs) and can be configured programmatically via RPC. A single Murmur daemon can also run multiple Murmur servers on different TCP/UDP ports.
Default Mumble port 64738 open by default (Amazon EC2 users will need to open additional manually).
Note due to incompatabilities with PHP7 the web UI compents have been removed from v15.x release. Remote Mumble server management can be done using either the offical Mumble app, or one of the many third party apps.
