Which technology its better to make a voice chat: Cirrus, FMS or XMPP?

Question

I am searching for a good technology to develop a voice chat, until now, the best I found are:

• Cirrus (Adobe)
• Flash Media Server (Adobe)
• XMPP

But all have good and bad features. i.e.:

• Cirrus runs only in the adobe servers rmtfp://example.adobe.com, is that reliable?, what will happen if some day adobe fall down?

• FMS it good, but I must pay -_-

• XMPP it good too, but I cant found reliable information for developing something. And zero information about voice chat.

Do you know some good tech to develop this type of app?

Answer 1

I'd suggest generally a media server, because it's a thing that you control (so better than cirrus) and because it's designed for streaming media (so better than xmpp)
However i'm not sure about fms, take a look at red5 (which is opensource) and wowza
