 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) (one per system)
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 “Connecting a
Music on Hold Source” on page 47.
For MoH WebUI configuration, see “Configuring Hold/Park Settings and
Music on Hold” in the Synapse Administrator’s Guide at
www.telephones.att.com/synapseguides.
 Door phone
See “Station Port (FXS) Door Phone Support” on page 25.
