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. /b On Feb 24, 2009, at 11:28 AM, Alex Gusak wrote:

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?
