1. Google Alchemy.
2. C/C++ SIP SDK or Your own libraries of SIP written in C
3. Convert them using Alchemy to SWF
4. Flex/Flash use your SIP functions (which allow you solid 100% audio codec's + real presence)
Concept: You can use Alchemy + Open C/C++ SDK == Flex web application release for VoIP platform (RTMP quality in SIP i am not happy yet)
- please increase this Alchemy community for Flex, we can rock the world
It has been quite sometime since Flash Media Gateway was released on labs; FMG is, well, made for this purpose.
That makes the solution look like: "Flex+FMS+FMG+SIP"
