Summary:                    Asterisk generates Ring instead of Coloring Ring
Back Tone (Early Media).
Description: 
Until 1.4.24 version it was possible to hear Coloring Ring back provided by
VOIP provider. After upgrading to latest version, coloring disappeared.

Also there is no coloring for all asterisk version, when we do sip
attended transfer.

to davidw:
This bug report is not related to 302/Refer transfers. There is a bug in
native Asterisk Call transfer feature when try to transfer call to outbound
sip trunk.

Also the current Refer implementation in Asterisk is not compliant with
SIP RFC-3515 and RFC-3261. There was a discussion in development mailing
list 3 years ago.

 Still Refer in the chan_sip is as it was 3 years ago.
