Patent abstract
When there is an arrival of a multicast call at a VoIP terminal on a call reception side, an SLIC sends out a ringing signal to a loudspeaker IF. The loudspeaker IF, after receiving the ringing signal, enters into a state in which voice is outputted from a loudspeaker even if a user does not respond. Compressed voice data is taken out of an IP packet received from a network and extended by a DSP to become voice data. Further, the voice data is converted by a CODEC into a voice signal, which is outputted from the loudspeaker.
