Based on RAT's faq, (Robust Audio Tools (RAT) is the audio tool used by
sipc to perform audio communications),
http://www-mice.cs.ucl.ac.uk/multimedia/software/rat/faq.html#nocard

You need to make sure the sound card is configured full-duplex.
Note also that being able to play CDs or MP3 files on the machine is not
an indication that your sound card is configured correctly for rat.
Playing out audio is a half-duplex operation, rat requires that your card
runs in full duplex mode.
