install the package sox (should be part of most distros).

  sox infile1 [...] outfile1

e.g: sox in1.wav in2.wav in3.wav out.wav

Sox generally tries to do "the right thing" with mixing inputs to
outputs. This means that is all the inputs are exactly in the same format 
and the extensions are right, you should have no problems, but if you,
you may need some extra hints using extra command-line switches.

BTW: sox supports gsm as well. Should also support ogg/vorbis quite
well. It generally supports decoding mp3-s, but at least on my system
(Debian Sarge) this support is quite spotty.
