I know. AT&T and T-Mobile use GSM (the GSM for wireless is the same as the GSM VoIP codec). I dunno if the CDMA operators translate to anything in the VoIP world or not.
I've tested with various codecs and I may use G.729 at some point, but for now I'm limiting myself to G.711 and G.722 once I get some business customers interested in it. ---------- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Bryan Scott" <[EMAIL PROTECTED]> To: "WISPA General List" <[email protected]> Sent: Monday, April 07, 2008 8:58 AM Subject: Re: [WISPA] Femtocells > The cell carriers aren't using G711.
