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.

Is this the desired behaviour then? I guess it does make sense that mixing
the 2 early media streams together for ringback would sound horrid :/ 

If so, the only way to force a ring on these types of dial strings (2 or
more destinations) is with the "r" parameter to the Dial application?
