Hi, we are working on a new codec for asterisk. It's early stages and the main goal is just to be able to "hear it" using normal client end points. So what I want is to be able to take a couple of normal G711 extensions, but have asterisk internally force a transcode to my new codec. In this way we can easily run up a bunch of listening tests with a wide variety of users very easily Ok, so how do I force this transcode in the middle, ideally without using two asterisk boxes? I clearly need two extensions to have (say) allow=g711, which means I need to persuade asterisk to route the call via a middle extension which is set to only allow the new codec. What are my options to achieve this? (meetme just occurred to me? could that work?) Any suggestions? Thanks Ed W
