New Revision: 110628

URL: http://svn.digium.com/view/asterisk?view=rev&rev=110628
Log:
Add an option (transmit_silence) which transmits silence during both Record() and DTMF generation. The reason this is an option is that in order to transmit silence we have to setup a translation path. This may not be needed/wanted in all cases.
(closes issue #10058)
