[asterisk-users] Transcoding issues with siren14

No, but as I said in a later email, I found the problem: when computing the
cost of a path, any downconvert has the same cost.  So

     siren14 -> slin -> slin32

is the same cost as

     siren14 -> slin16 -> slin32

which is wrong.

I fixed this by adding the magnitude of the difference in the sampling
rate to the cost, but I'm not sure if that's the right solution.
