** Description      This callout function is executed by PAN when a server is
**                  started by calling BTA_PanEnable().  This function can be
**                  used by the phone to initialize data paths or for other
**                  initialization purposes.  The function must return the
**                  data flow mask as described below.
**
**
** Returns          Data flow mask.
