Summary:                    No ringback when 2 or more destinations in dial
string
Description: 
If I have 2 or more destinations configured as part of the dial string, I
hear no ringback tone from the media in 183 Session Progress.

If I take the same two parameters and dial them individually then I hear
the ring tones passed back.

I have tried with all combinations of prematuremedia=yes/no and
progressinband=yes/no/never on the provider trunks, in addition to having
the Ringing() application preceed the dial (when I preceed the Ringing()
app, then I get 1 ring before the 183 Session Progress stops the ringing -
early media I presume)

It appears that there may be an issue with bridging 2 or more
destinations.

This issue appears to be identical to issue 0010032 which was suspended
due to lack of feedback.

That behaviour sounds reasonable.  Maybe it should be overriding the
Progress call and sending 180 Ringing again.  The problem, as I see it, is
that giving ringback after 183 for multiple destinations could require it
to mix ringbacks from all sources, which might well sound horrible!
