The software that supports this voice operation uses a sound card within the appliance to playback and record. Other functions that the 56K PCI Voice Modem SF-1156IV R9A can perform include dialing or answering calls with the use of the sound card's speakers, headphones or microphone. Additional software can be used with the voice modem in order to boost its functionality. Such is the case with programs that are able to record calls to wav format files. This appliance is full duplex enabled meaning that it talking and listening can be done simultaneously which enhances functionality. Without full duplex support the quality of voice is greatly compromised.
