Use PC Cross Mute for adjacent Dispatch positions that should mute each other's local audio. Enable the feature on the intended positions and assign them the same Cross Mute ID.
For the same-Gateway arrangement described in this FAQ, configure the nearby PCs as one cross-mute group. The ID identifies the intended group of positions; it is not a radio subscriber ID or talkgroup number.
- Have an administrator enter Edit mode in Dispatch.
- Open Options → Audio Presets → Configure and select the workstation's preset.
- On the General tab, enable PC Cross Mute and choose the Cross Mute ID.
- Use the same ID on the adjacent positions that belong in that group. Give positions in a different physical room a separate ID when they should not share the same muting behavior.
- Save the configuration and test transmissions from each position, along with normal incoming radio traffic.
Identify the audio path before changing more settings. Sound from a nearby speaker entering an open microphone is an acoustic issue. The same radio transmission arriving through more than one radio/Gateway is a separate duplicate-audio situation. The installation guide describes distinct RF cross-muting and duplicate-source options for those paths, including PTT-ID requirements.
Also check speaker/microphone placement, headset use, and audio levels. Cross-muting is an audio configuration feature, not a channel-access permission or a substitute for checking the selected output devices.
For mixed client versions or a different Gateway arrangement, have CTI confirm the applicable cross-mute behavior for the installation before copying a configuration from another site.
