Whether or not slinear is spoken over the wire or not, it still
represents the most audio data of any of the codecs. Asterisk then does
a conversion to the codec you need for over the wire. ulaw and alaw
would be less audio information when you convert to another codec.

And for system load, without having to go from ulaw or alaw to sliniear
and then to codec of choice reduces computational load.
