Asterisk sslv3警报握手失败

Question

我使用的是Ubuntu v14.04.3 LTS和Asterisk 13.3.2。当我尝试从sipml5客户端打电话给我的分机以播放演示恭喜音频时，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 

另外我使用的是Chrome v54。

我认为这个错误是与openssl，但没有得到一个正确的和完整的答案还没有解决这个问题。有谁知道如何解决这个问题？

Answer 1

通过升级openssl解决了这个问题。下面 使用命令在Ubuntu升级的OpenSSL低于14

# 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 

使用命令来检查OpenSSL的版本

# 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，再重新键

# 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"
