Systems and methods for volume control over intercom trunk lines. One example method includes receiving, from a first keypanel coupled to a first intercom, a call request identifying a remote keypanel coupled to a second intercom. The method includes transmitting a trunk request based on the call request and receiving a trunk setup message. The method includes activating a first crosspoint to provide a two-way audio connection between the first and second intercom devices. The method includes applying a trunk gain value to the first crosspoint based on the remote keypanel and transmitting, with an audio gain based on the trunk gain value, an audio stream received from the first keypanel. The method includes receiving, from the second intercom, a gain adjustment value associated with the first keypanel and the remote keypanel and applying an adjusted trunk gain value to the first crosspoint based on the gain adjustment value.

Volume control over shared trunk lines in intercom systems

An intercom device and a method of recording an audio stream at the intercom device. The intercom device includes a user interface, a memory, and an electronic processor. The electronic processor is communicatively coupled to the user interface and the memory and is configured to receive a user-selectable entry from an input mechanism of the user interface. The electronic processor sets an away mode of the intercom device in response to the user-selectable entry. An audio stream is received by the intercom device from another intercom device. Are cord signal indicative of a request to record the audio stream is also received from the another intercom device. The intercom device records the audio stream in the memory in response to receiving the record signal when operating in the away mode.
