Summary:                    Oneway audio from SIP phone to FXS port after FXS
port gets a CallWaiting pip
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, also no outbound audio to SIP
phone.

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.
