This mode is only supposed to be used by cases when:
- in-dialog offerer doesn't have own MoH capabilities; and
- still want the recipient to hear the MoH music; hence
- an offerer checks whether a recipient is capable of MoH,
and launches a player based on given capabilities;
- the rest functions the same as with usual MoH hold;
Other information:
- `mode=reflect` is only to be used within dialog,
so, it's not meant for a session origination,
and hence stands alone from other MoH option flags
that actually give a metadata (e.g. blob data)
- `mode=reflect` hence contradicts with `mode=sendrecv`
which in its turn serves another purpose
Usage:
- `moh => { mode => 'reflect' }`
