Media Negotiation
The Media Negotiation node object in the anynode frontend consists of the configuration sections: Object, Settings, RTP/RTCP including negotiation & T38 UDP transport layer, ICE protocol, and Replication. There can also be a profile selected which is set by default to 'Standard (secure)'.
In the Settings dialog, the Security level and the Media setup with its audio capabilities and events can be specified. The default settings, e.g., the G.711a, G.711u, and Opus codecs in the Media Setup, usually work well.
