Asterisk 故障排查

Hangup Cause Mappings

系统问题排查

硬件的问题

中断

版本问题

考虑降级测试

驱动问题

如果是用的 OpenVox, 那么需要从新编译
编译驱动时和内核版本有关

系统问题

切换操作系统
AsteriskNow, Alpine, CentOS

配置问题
SIP/PJSIP 的问题

切换使用 chan_sip 和 chan_pjsip 进行尝试

PJSIP 的问题

可能是由于 pjproject 的 bug 问题, 使用 asterisk bundle 的 pj

诊断命令

CLI commands useful for debugging

# 系统状态 - 内存, 运行时间
core show sysinfo
# 查看线程
core show threads


# 查看通话统计
# uptime 会显示通话时间
core show calls uptime
# 查看通道信息
core show channels
# 终止一个 channel
channel request hangup SIP/4003-00000a2f

# 查看注册的 PBX 交换
core show switches

# 开启日志进行排查
core set verbose 4
core set debug 4

# 开启 SIP 日志
pjsip set logger on

From 头包含的地址无效导致解析问题

尝试修改 hostname

error parsing header 'Contact' error parsing header 'From'

From: "100" <sip:100@0f7a4948f2>;tag=b6a43727-f5d2-40af-8a93-80739de6d092

Contact: <sip:asterisk@0f7a4948f2ba:5060;transport=ws>

这里的 0f7a4948f2 是不符合 uri 规范的，会导致部分客户端异常

0f7a4948f2 是 hostname - 可以修改

PJSIP 会将请求过来的地址进行转换

same => n,DumpChan()
same => n,NoOp(CALLERID ${CALLERID(all)})
same => n,NoOp(From ${PJSIP_HEADER(read,From)})

原始的 From 里是 IP 地址

接口 originate 一定概率没有声音

No voice when using AMI originate between two external destinations

查看通话数量和当前开启通道

asterisk -rx 'core show channels'

终端问题排查

确保 context 正确
尝试关闭 ICE

常见 HTTP 异常状态码

No Response 408 Request Timeout 500 Internal Server Error 502 Bad Gateway 503 Service Unavailable 线路忙、拥塞 504 Server Timeout Any 600-class response

401 Unauthorized 407 Proxy Authentication Required

Assertion failed: sess && sess->endpt

该异常后程序会直接崩溃
pjproject sip_auth_client.c#L507
https://github.com/asterisk/pjproject/blob/master/pjsip/src/pjsip/sip_auth_client.c
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842878
asterisk 14.4.1 依赖的 pjproject 2.5.5 未修复
代码
- #1946 Assertion in deinitializing client auth session when dialog creation fails
- changeset#5401
  - 避免处理未初始化的客户端授权会话
- changeset#5373
  - 添加了断言
建议编译 asterisk 使用 bundle pjproject 的形式, 避免外部依赖, 并且 asterisk 也有不少针对 pjproject 的补丁

Assertion failed: sess && sess->endpt (../src/pjsip/sip_auth_client.c: pjsip_auth_clt_deinit: 507)

Bridge: Could not create class basic. No technology to support it.

可能是没有加载 bridge 模块

Couldn't execute statement: SQL logic error

看看是不是数据库没有权限
