Summary:                    [regression] No Ringing / No Playback when call is
getting forwared by a phone
Description: 
If an extension tries to setup a static call forwarding (on the phone) to
another internal extension. The call is getting redirected - but the caller
does not hear a ringing or can not hear a playback.

Example 1:
Ext "100" has setup a 302 redirect to extension "5". Somebody is calling
SIP/100 - the call is getting forwared to extension "5" to play the
Playback. The caller does not hear anything.

Example 2:
Ext "100" has setup a 302 redirect to extension "101". Somebody is calling
SIP/100 - the call is getting forwarded to extension "101". The phone on
extension 101 is ringing but the caller of 100 does not hear a ringing
tone.
There is no problem with answering the call - both can talk without
Problems.

I've confirmed the problem on a 1.4.29 build and also confirmed that it is
working in 1.4.30.

I went ahead and reviewed some differences between the releases and found
that the cumulative fixes on channels/chan_local.c also fixed this
problem.

http://svnview.digium.com/svn/asterisk/branches/1.4/channels/chan_local.c?r1=249536&r2=237318

I think the key really was in r 244785 the code to set the state for
ringing was incorporated but it also regressed, the regression was cleaned
up in r249536

I've applied this change in my lab and confirmed that it restores ringback
to the case where a phone forwards a call.
