From 98504fec8ee8fde7eb2a6378046f3d35bfba961a Mon Sep 17 00:00:00 2001 From: Kinsey Moore Date: Tue, 23 Jul 2013 13:52:06 +0000 Subject: Add DTLS-SRTP support to chan_pjsip This patch introduces DTLS-SRTP support to chan_pjsip and the options necessary to configure it including an option to allow choosing between 32 and 80 byte SRTP tag lengths. During the implementation and testing of this patch, three other bugs were found and their fixes are included with this patch. The two in chan_sip were a segfault relating to DTLS setup and mistaken call rejection. The third bug fix prevents chan_pjsip from attempting to perform bridge optimization between two endpoints if either of them is running any form of SRTP.
