Absolutely agree, ITU standard is 64Kbits/sec.
VoIP traffic with U-law per channel is 83Kbits/sec. VoIP traffic with U-law per call is 166Kbits/sec [measuring bandwidth per call] ----- Original Message ----- From: "Nicolas Bougues" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, March 10, 2004 9:55 AM Subject: Re: [Asterisk-Users] Asterisk Codecs [G.729] > On Wed, Mar 10, 2004 at 09:03:57AM -0800, <Unavailable ID> wrote: > > Rich, > > > > In real world, using real tool, getting real number.
