How to implement RFC3960?


Diego Riera

Hire a programmer.

This is about client behaviour (i.e. Asterisk’s handling of the incoming side). I don’t know how Asterisk responds to a conflict between 180 Ringing and the actual presence of early media.

If you were talking about early media on the server side, which this RFC is not about, then you would use Progress().

What is the real world problem that you are trying to solve?

I need implement RFC3960 because Microsoft Lync 2010 require this.

The FreeSwitch is OK RFC3960, but I would like to use Asterisk.
