5.4.6 User Sounds

The

intercoms provide standard signalling of operational statuses by

2N Helios IP

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
Call busy tone
Call hang-up
Invalid input
Invalid Phone Book position
Switch activation

You can either completely mute the above-mentioned sounds or replace them with a
sound file of your own simply recorded into the intercom. The sound file must have the
WAV format and use PCM encoding with 8 kHz sampling frequency and 8/16-bit sample
resolution, and the file size may not exceed 128 kB. The maximum file playing time is
limited to approximately 16 seconds for 8-bit and 8 seconds for 16-bit resolution.

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.
