IIRC, that describes the time in milliseconds estimated to transcode
between the codecs.
Do you use any of those codecs? If not, you might want to noload them in
modules.conf
What sort of CPU is that running on? Is it a normal flavour of linux?

Hi Guys,
What exatly do the numbers underneath the codecs mean when one does a "core show translation"?
I have a system which from time to time shows different numbers under g729 and the codec stops responding. Once I restart asterisk everything goes back to normal.
Follwoing is output of "core show translation" pre and after asterisk restart.
