The Telephony Control Server-based feature music-on-hold enables callers to hear music while their call is being held. The feature can be directly assigned to a subscriber or be integrated in a feature profile that is directly assigned to the subscriber. In case of a collective line the trigger number of the collective line is regarded as subscriber. If the music-on-hold feature has been configured, a subscriber always hears music while being held in waiting state. This applies to: making a consultation call, holding an active call, manually holding an active call and CSTA-initiated hold.
Lotus Sametime Unified Telephony SIP devices can also locally provide music-on-hold. However, the Telephony Control Server-based feature is then preferred to the local one.
The system administrator determines the music-on-hold used by specifying the drop name that is linked to the music file. This music can be the same each time a subscriber's call is held. The administrator can optionally specify music files for:
Each feature profile. That means, all users who have been assigned this feature have their callers listening to the same music (if applicable).
Each trigger number. That means, with calls of the associated collective line the same music is played (if applicable).
Each single line
The availability of this feature depends on the services assigned to the holding subscriber. When this feature is invoked, the following happens:
- The unit (endpoint, line, gateway) where the music is to be heard is connected to a Media server that provides the music. This Media server can be a separate one or the same Media server that also provides other system announcements.
- Since music-on-hold is considered a system announcement, a default announcement connection is set up between the receiving unit and the Media server.
- The system routes the announcement ID for the music source and the endpoint information to the Media server.
- The Media server plays the music until the caller is released from the waiting loop.
It is the customer's responsibility to create and provide the Wav files for the music-on-hold.
The Wav files are stored on the Media server.
The music-on-hold can also consist of several linked files and be played in a loop.
