[OpenSIPS-Users] add sdp on 180 Ringing and play file as ringback tone

[Daniel Goepp]

Although I do not believe it is technically a violation of the RFC, it is
not recommended best practice, and would be a rare implementation.  The
most common way to support ringback (early media) is with a 183 w/SDP
session progress.

For a little more information:

Of course some googling will give you tons more opinions about ring back
and early media.
