Mr. Roboto.
LPC10 is a very old codec, from early 1980s. LPC10 doesn't do a good job with pitch detection so it tends to have a 'robotic' sound. With advent of MELPe, anyone needing bitrates 2400 or less should not be using LPC10. -Jeff -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
