From e5f1f0496a0abdf472e81f1f818a2a942635b64a Mon Sep 17 00:00:00 2001 From: Mark Michelson Date: Mon, 21 May 2012 19:22:25 +0000 Subject: Add "send to voicemail" Digium phone functionality to Asterisk. This change accommodates two methods by which calls can be directed to a user's voicemail. * Incoming calls can be redirected to any user's voicemail. * Established calls can be blind transferred to any user's voicemail. Digium phones indicate the desire to direct a call to voicemail by using a Diversion header with a reason parameter of "send_to_vm". This patch adds the "send_to_vm" reason as a valid redirecting reason. In addition, chan_sip.c has been modified to update redirecting information on the transferred channel by reading a Diversion header on a REFER request.
