Summary:                    MOH at SIP device not heard when put on hold by an
FXS port if it's a Call Waiting call
Description: 
Internal SIP phone initiates a call with FXS port on TDM800P.

External call comes in on FXO port, and attempts to ring FXS ports.
Call waiting beep is heard at FXS port.

Then FXS port hook flashes, the FXO port is then connected to FXS as
expected.
But SIP device should hear MOH, but has dead air.

If the FXS port hook flashes to the SIP device, the FXO call then does
hear MOH.
Hook flash again back to FXO call, SIP hears nothing.

---------------------------------------------------------------------- 
Another related issue, is one way audio from first caller, as soon as the
call waiting beep starts.

Can be corrected by 'B' pressing DTMF key!!!!! But not by 'A' pressing a
key.

SIP 'A'  --call 1--->>---------[ASTERISK]---->>----'B' FXS port
SIP 'C'  --call 2--->>---------+

'A' calls 'B', 'B' answers, all ok so far
'C' calls 'B', 'B' hears beep
   A<-B audio is dead!
   A->B audio OK
   'B' presses a DTMF key
   A<->B audio now OK

'B' now hook flashes to answer 'C'
   'A' has MOH
   C<->B audio OK

'B' now hook flashes to 'A'
   'C' has MOH
   A<->B audio OK.
