[asterisk-users] AMR codec for Asterisk 1.6.1.X

[Kyle Kienapfel]

 == Registered translator 'amrtolin' from format unknown to slin, cost 4000
 == Registered translator 'lintoamr' from format slin to unknown, cost 32002

Probably shouldn't be listing it as "unknown"

Have you tried using that AMR codec beyond commands in the asterisk cli?

Did the patch apply cleanly?
