Asterisk sslv3 警报握手失败

Question

我正在使用 Ubuntu v14.04.3 LTS 和 Asterisk 13.3.2。当我尝试从 sipml5 客户端呼叫我的分机以播放演示祝贺音频时，我的呼叫立即断开。当我检查星号日志时，出现以下错误：

[2016-08-24 06:07:49] ERROR[31730][C-0000000c]: res_rtp_asterisk.c:2042 __rtp_recvfrom: DTLS failure occurred on RTP instance '0x7f547c013c68' due to reason 'sslv3 alert handshake failure', terminating

[2016-08-24 06:07:49] ERROR[31730][C-0000000c]: utils.c:1402 ast_carefulwrite: write() returned error: Broken pipe

我也在使用 Chrome v54.

我认为这个错误与openssl有关，但还没有得到正确和完整的答案来解决这个问题。有人知道如何解决这个问题吗？

Answer 1

通过升级 openssl 解决了这个问题。使用以下命令在 Ubuntu 14

中升级 openssl

# echo 'deb http://us.archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse' > /etc/apt/sources.list.d/xenial.list
# aptitude update
# aptitude install -y openssl libssl-dev
# rm /etc/apt/sources.list.d/xenial.list
# aptitude update

使用以下命令检查openssl版本

# ldd /usr/sbin/asterisk  | grep libssl
libssl.so.1.0.0 => /lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f33ce117000)

# strings /lib/x86_64-linux-gnu/libssl.so.1.0.0 | grep 1.0.2
OPENSSL_1.0.2
OPENSSL_1.0.2g
SSLv3 part of OpenSSL 1.0.2g-fips  1 Mar 2016
TLSv1 part of OpenSSL 1.0.2g-fips  1 Mar 2016
DTLSv1 part of OpenSSL 1.0.2g-fips  1 Mar 2016
OpenSSL 1.0.2g-fips  1 Mar 2016

# openssl version
OpenSSL 1.0.2g-fips  1 Mar 2016

在此之后删除所有现有的星号键并再次重新创建键

# rm /etc/asterisk/keys/*
# cd /usr/src/astersik*/contrb/scripts
# sudo ./ast_tls_cert -C pbx.mycompany.com -O "My Super Company" -d /etc/asterisk/keys
# asterisk -rx "reload"
