Three points:

1. some nice features, see http://speex.org/ . Some are unique. Though
not all are applicable to transcoded usage with Astrisk.
2. Like other codecs from Xiph.org (vorbis, theora, flac, the ogg
container), it is probably the most patent-free of the
decently-compressed codecs.
3. It is really handy when you want to stress the CPU. gsm requires much
more calls to get to the same load level :-(

Thus you'll typically find it in soft phones. You should expect it to
give better quality than gsm.
