4.10.1. Mode
To enable this feature the „Mode‟ drop down box must be set to „local‟ or „remote‟.
Local mode only distributes the talk back audio within the local Mesh. Remote mode allows
the onward distribution of this audio on an external IP network using RTSP protocols.
The remote mode also allows external „eavesdropping‟ of the audio using the url:
rtsp://ip_address_of_unit/audio.sdp
Audio may also be sent to that unit using the same port as the RTP packet. The audio format
must be G726-32 with a payload size of 512 bytes.
