Loud Ringers

Loud Ringer devices must be connected to an FXS port assigned as Voice (default
setting). Loud Ringers can be used for alerting users of an incoming call via a
loud speaker and are treated within Synapse as a regular analog phone instead
of OHP equipment. This type of overhead alerting can only be done by including
the voice FXS port in a Ring Group.
A source for Music On Hold (MoH)

You can use the ATA to route MoH audio input to outside held, parked, or queued
calls. When external callers are placed on hold, parked, or enter a call queue,
they hear the audio source provided by the MoH input. The system administrator
must configure the MoH in the WebUI. For more information, see
