[Freeswitch-users] Don't work playback after bypass media mode.

[Anthony Minessale]

it's against the SIP spec to re-negotiate media before you have answered.
the transaction to negotiate the SDP from the original call has not
completed so it's illegal to send a re-invite.

instead you should use bypass_media_after_bridge=true so the bypass only
happens when the bridge works.
