Summary:                    race condition in handling writes to proslic
LINEFEED register (64)
Description: 
Originally reported on asterisk-users by Barry Miller.  

The wctdm24xxp driver has a problem where a VMWI IOCTL call followed
immediately by a ONHOOKTRANSFER IOCTL call will cause the ONHOOK transfer
request to be dropped.  This occurs if the write to the proslic's LINEFEED
register for the VMWI ICTL call is not completed when the ONHOOK transfer
request IOCTL is processed.

---------------------------------------------------------------------- 
This problem manifests itself when sending MWI FSK spills after a FXS
channel goes on-hook or the channel's voicemail state changes.   In this
case, the spill never gets sent as the proslic is not properly placed into
ONHOOKTRANSFER mode.
