Summary:                    [patch] ast_readstring (multiple DTMF input) doesn't
transmit silence to the caller even if transmit_silence=yes
Description: 
ast_readstring (multiple DTMF input) doesn't transmit silence
to the caller even if transmit_silence=yes.

Asterisk should transmit silence when transmit_silence=yes,
otherwise phone might hang up during DTMF input by RTP timeout.

Attached patch will fix the problem.

      Transmit silence when reading DTMF in ast_readstring.
      
      Otherwise, you could get issues with DTMF timeouts causing hangups.
