The OpenScape 4000 SoftGate can act as a music on hold (MOH) or announcement source provider. It works in a similar way as external equipment connected to an analog line. The OpenScape 4000 SoftGate provides virtual SLMA board and virtual TMOM board with saved voice files which emulate real SLMA and TMOM board with connected external music equipment. As music source audio files are used (for requirements please refer to Section 7.2, “Service Information”).

Music or announcement can be switched to any destination within OpenScape 4000 SoftGate (HFA phone, SIP phone, SIP trunk) as well as to any device in another access point or host shelf (TDM phone, analog phone, …).
