5.4.7 User Sounds
The 2N LTE intercoms provide standard signalling of operational statuses by tone sequences;
refer to the Signalling of Operational Statuses subsection. If you find the standard sound
signalling inconvenient, modify the sounds for the following statuses:
Ringing before answering call
Ringback tone
Call busy tone
Call hang-up
Invalid input
Invalid user position
Switch activation
You can either completely mute the above-mentioned sounds , replace them with one of the ten
predefined sounds, or simply record a sound file of your own into the intercom. The sound file
must have the WAV format and use PCM encoding with 8/16 kHz sampling frequency and 8/16-
bit sample resolution, and the file size may not exceed 256 kB.
Frequency Bits for sample Sound length Quality
16 kHz 16 bit up to 8 s 1 best
16 kHz 8 bit up to 16 s 2
8 kHz 16 bit up to 16 s 3 (not recommended
combination)
8 kHz 8 bit up to 32 s 4 low
You can also play the recorded files via Automation using the Action.PlayUserSound and,
optionally, with the aid of the intercom speaker and/or directly into the phone call.
