[Freeswitch-users] new ilbc lib

[Brian West]

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 at 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.
