Hi Steve, Yes it looks easy to add just the iLBC codec, I added iLBC codec in iaxclient library, I just hard coded the things to use iLBC or GSM when init,without any structure of codecs selection and sending codecs to other end when starting new session but the sound quality is not good as well as having some echo problems too. Right now I use 20ms rate. What do you think what should be the problem ? 20ms is supported on * ?
