Hello.

After upgrade to version 1.0.3 we have a problem with the codec iLBC
(I think that this is due to the transition to a new ilbc libs 1 week
ago).
Very poor quality for calls to the codec iLBC mode=20 (crack in the
dynamic). iLBC mode=30 works well.
Tested with phones and Zoiper SJPhone.

After a rollback to the old version of FreeSWITCH 1.0.2 this is not a
problem, iLBC works fine in both modes (mode = 20 and mode = 30).

What could be the problem?

The problem comes up that the default is 30... the chances are that
your phone doesn't set the mode= line so we default to 30 when this
takes place. Not setting the mode= line in the FMTP usually means
30ms... which is the default. So to force this always to 30 you can
allow iLBC@30i, because if you invite to me with 20 and I 200 ok you
30.. you are to use 30 no exceptions. Most phones do not obey this
rule.
