I only have a view of some of the pieces, so this might be unworkable. I don't know much about Red 5 yet.
On the Asterisk side, it can already send audio to the sound card. Through ALSA or OSS configuration, you 'dial' the console like this 'Dial Console/dsp|20' to send audio from an Asterisk channel to the sound card -- like a phone call or a recording. We use it all the time to let people dial up the paging system and make announcements. I've never looked to see if we can use the microphone input as a source for audio into Asterisk. I imagine making a new plug-in for Asterisk or modification to chan_oss.c that would allow you to 'dial' Red5 and start participating in a stream. If you're able to dial it, then you could include it in a conference call or meet-me session. Therefore, you could have an audio SIP conference call with a dozen participants streaming to and from Red5 with one connection. Forgive me if I'm stating or re-stating something you already know.
