MWI Off
A technique to turn off the MWI in this switch, using dx_dial( ) with the dial
string, is to:
1. Go off-hook using the dx_sethook( ) function.
2. Call the dx_dial( ) function. The dial string is
<ESCF><extension><ESCF> (optional pause character may be used).
3. Go on-hook using the dx_sethook( ) function again.
NOTE: <ESCF> means the Escape character followed by F.
