ring tone pattern for calls received from each external sensor, to distinguish between them.
Conditions
• Hardware Requirement: An external sensor and the DPH card
• Some devices may be unable to communicate correctly with the PBX. Confirm compatibility with the
manufacturer of a device before installing it.
