Hello,

At r15025 the ringback tone handling has changed.

The old method:
When ringback was set, early media was ignored, meaning that if you got
183 with SDP, ringback was generated locally.

The new way:
When ringback is set, the ringback tone is generated only when there is
no early media (thus 180 w/o SDP or 183 w/o SDP). When early media is
presented, it will be used as ringing indication.

To get the same behaviour as before r15025, you have to set the following:
ignore_early_media=true
ringback

Some wiki pages were changed to report the new behavior.

Many thanks for guys for fix/feature, especially for anthm and bkw.

Kind regards,
   Tamas

ps.: issue was related with FSCORE-454.
