Summary:                    No audio is passed from MOH when using originate to
a remote peer
Description: 
No audio is passed from MOH when using originate to a remote peer

If you issue a Playback(), before MusicOnHold, audio will flow.

---------

extend context services {
  1 => {
    Answer(500);
    MusicOnHold();
  }

  2 => {
    Answer(500);
    Playback(lunch);
    MusicOnHold();
  }
}

5506 is a polycom phone registered on pbx A
on pbx A:
  asterisk -rx "originate SIP/5506 extension 1 at services"

    -- Executing [1 at services:1] Answer("SIP/5506-00000014", "500") in new

Everything is fine and dandy.  Here's the problem:

26213 is a polycom phone on demo1 (which is also asterisk).. and this bug
exhibits itself whether using sip or iax.

on pbx A
asterisk -rx "originate SIP/demo1-sip/26213 extension 1 at services"

    -- Executing [1 at services:1] Answer("SIP/demo1-sip-00000015", "500") in
new stack
    -- Executing [1 at services:2] MusicOnHold("SIP/demo1-sip-00000015", "")
in new stack
    -- Started music on hold, class 'default', on channel
'SIP/demo1-sip-00000015'

no RTP!

Now we try a Playback() beforehand.

on pbx A
asterisk -rx "originate SIP/demo1-sip/26213 extension 2 at services"

    -- Executing [2 at services:1] Answer("SIP/demo1-sip-00000016", "500") in
new stack
    -- Executing [2 at services:2] Playback("SIP/demo1-sip-00000016",
"lunch") in new stack

I'm not sure what the resolution will be here -- for your work around, you
could also use Playback(silence/1) if you need to trigger something to get
the audio flowing first, but don't actually want to play something the
caller can hear.
