Re: [asterisk-users] Different codecs for reading and writing

Hello Everyone! Thank you for all the information. I am wondering how the Asterisk community has been working on solutions to deal with the asymmetric quality of ADSL. Voip is becoming popular and a bottleneck does exists on the ADSL upload side. Elliot On Sun, Aug 2, 2009 at 3:17 PM, Kevin

Re: [asterisk-users] Different codecs for reading and writing

I'm not sure there IS an issue, per se. There are lower bitrate codecs that will work fine for voice communications in both directions. But if you're trying to force a low-end codec to the upstream, that just means the downstream on the remote end is going to be stuck with a low-end codec. And if

Hello! I am wondering how to configure Asterisk and devices so I can use different codecs for upstream and downstream packets. Thank you, Elliot ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15

Hello, Thank you...do you know if IAX can do this? The reason for doing is this is to get over the adsl upload/download discrepancy. While G711 gives terrific quality, it is not always that feasible for the upload direction, which has much more limited bandwidth. Accordingly, it would be
