Some recent changes to CVS may have changed this behavior behind your 
back :-) When Asterisk sets up a transcoding path now, it _always_ goes 
through slinear, unless the new optimization is turned off (via a 
setting in asterisk.conf). Yes, this means that xlaw-to-xlaw conversion 
is somewhat slower, but it also means that all applications that want to 
deal with slinear on a bridge can do so easily.

It may also mean that xlaw-to-xlaw will, in fact, cause PLC to work its 
magic, but I can't say for sure.
