Hello Freeswitch devs, we would like to contribute the bypass media feature for the skinny implementation in freeswitch. I've contacted Mathieu and Nathan (the mod_skinny devs/authors) previously, and they recommended to write to this mailing list for the core questions. My first step would be to get a general understanding how to accomplish that feature, and any advice would be very much appreciated. My background: I've been contributing a few patches skinny already, but don't have a real understanding of the core functionality of freeswitch. From the discussion with Mathieu and Nathan, we've agreed that implementing Codec negotiation would be the first step - which is not yet implemented in Skinny. Switch_core_media seems to offer that functionality in general, however Skinny does not operate with SDP descriptions. So my first questions would be: * Should mod_skinny generate SDP generations to interface with the freeswitch codec negotiation? Or are there any other alternatives to interface with the current implementation? * Do you have any recommendations where to look at, maybe a simple implementation? I've been looking into sofia, but I felt a little lost to be honest.... * are the any other requirements to consider? Thank you very much, Simon
