Indeed, it was.

You can always see which codec is in use by doing a SIPpacket capture and
looking at the above negotiation exchange to see what got agreed on.

Try "core show translation" on your Asterisk command line and check that the
table has an entries in both directions for speex (left) to slin (top) and
slin (left) to speex (top).
The numbers tell you how many microseconds *your* server takes to transcode 1
second of audio between the two codecs.
You can also try "core show translation paths speex" to get a list of the
codecs which can and cannot be converted to, with a guide to the method used
for trancoding that combination where possible.
All matter in the Universe can be placed into one of two categories:
1. Things which need to be fixed.
2. Things which need to be fixed once you've had a few minutes to play with
Please reply to the list;
please *don't* CC me.
