电话呼出的SIP协议和FreeSWITCH日志
SIP呼叫其实很简单我们以电话呼出为例。这里呼出例子是根据上一篇文章来的就是1000分机通过电话外线呼叫10086号码。SIP协议是这样的 #mermaid-svg-Z7ay1j5Ge6leDfyo {font-family:"trebuchet ms",verdana,arial,sans-serif;font-size:16px;fill:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .error-icon{fill:#552222;}#mermaid-svg-Z7ay1j5Ge6leDfyo .error-text{fill:#552222;stroke:#552222;}#mermaid-svg-Z7ay1j5Ge6leDfyo .edge-thickness-normal{stroke-width:2px;}#mermaid-svg-Z7ay1j5Ge6leDfyo .edge-thickness-thick{stroke-width:3.5px;}#mermaid-svg-Z7ay1j5Ge6leDfyo .edge-pattern-solid{stroke-dasharray:0;}#mermaid-svg-Z7ay1j5Ge6leDfyo .edge-pattern-dashed{stroke-dasharray:3;}#mermaid-svg-Z7ay1j5Ge6leDfyo .edge-pattern-dotted{stroke-dasharray:2;}#mermaid-svg-Z7ay1j5Ge6leDfyo .marker{fill:#333333;stroke:#333333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .marker.cross{stroke:#333333;}#mermaid-svg-Z7ay1j5Ge6leDfyo svg{font-family:"trebuchet ms",verdana,arial,sans-serif;font-size:16px;}#mermaid-svg-Z7ay1j5Ge6leDfyo .actor{stroke:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);fill:#ECECFF;}#mermaid-svg-Z7ay1j5Ge6leDfyo text.actortspan{fill:black;stroke:none;}#mermaid-svg-Z7ay1j5Ge6leDfyo .actor-line{stroke:grey;}#mermaid-svg-Z7ay1j5Ge6leDfyo .messageLine0{stroke-width:1.5;stroke-dasharray:none;stroke:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .messageLine1{stroke-width:1.5;stroke-dasharray:2,2;stroke:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo #arrowhead path{fill:#333;stroke:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .sequenceNumber{fill:white;}#mermaid-svg-Z7ay1j5Ge6leDfyo #sequencenumber{fill:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo #crosshead path{fill:#333;stroke:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .messageText{fill:#333;stroke:#333;}#mermaid-svg-Z7ay1j5Ge6leDfyo .labelBox{stroke:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);fill:#ECECFF;}#mermaid-svg-Z7ay1j5Ge6leDfyo .labelText,#mermaid-svg-Z7ay1j5Ge6leDfyo .labelTexttspan{fill:black;stroke:none;}#mermaid-svg-Z7ay1j5Ge6leDfyo .loopText,#mermaid-svg-Z7ay1j5Ge6leDfyo .loopTexttspan{fill:black;stroke:none;}#mermaid-svg-Z7ay1j5Ge6leDfyo .loopLine{stroke-width:2px;stroke-dasharray:2,2;stroke:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);fill:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);}#mermaid-svg-Z7ay1j5Ge6leDfyo .note{stroke:#aaaa33;fill:#fff5ad;}#mermaid-svg-Z7ay1j5Ge6leDfyo .noteText,#mermaid-svg-Z7ay1j5Ge6leDfyo .noteTexttspan{fill:black;stroke:none;}#mermaid-svg-Z7ay1j5Ge6leDfyo .activation0{fill:#f4f4f4;stroke:#666;}#mermaid-svg-Z7ay1j5Ge6leDfyo .activation1{fill:#f4f4f4;stroke:#666;}#mermaid-svg-Z7ay1j5Ge6leDfyo .activation2{fill:#f4f4f4;stroke:#666;}#mermaid-svg-Z7ay1j5Ge6leDfyo .actorPopupMenu{position:absolute;}#mermaid-svg-Z7ay1j5Ge6leDfyo .actorPopupMenuPanel{position:absolute;fill:#ECECFF;box-shadow:0px 8px 16px 0px rgba(0,0,0,0.2);filter:drop-shadow(3px 5px 2px rgb(0 0 0 / 0.4));}#mermaid-svg-Z7ay1j5Ge6leDfyo .actor-man line{stroke:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);fill:#ECECFF;}#mermaid-svg-Z7ay1j5Ge6leDfyo .actor-man circle,#mermaid-svg-Z7ay1j5Ge6leDfyo line{stroke:hsl(259.6261682243, 59.7765363128%, 87.9019607843%);fill:#ECECFF;stroke-width:2px;}#mermaid-svg-Z7ay1j5Ge6leDfyo :root{--mermaid-font-family:"trebuchet ms",verdana,arial,sans-serif;} MicroSIP FreeSWITCH IAD Invite 010086 对应日志里的黄色标记 sofia/internal/1000192.168.3.13 100 Trying Invite 10086 100 Trying 180 Ringing 180 Ringing 200 OK 对应日志里的黄色标记 Channel [sofia/external/10086] has been answered 200 OK 上述就是SIP消息信令 下面开始RTP数据声音 吧啦吧啦 吧啦吧啦 MicroSIP FreeSWITCH IAD 从FreeSWITCH日志上这样记录 2024-03-06 19:05:33.172906 [NOTICE] switch_channel.c:1104 New Channel sofia/internal/1000192.168.3.13 [1ea401e7-6c7b-481f-8752-45742a320922] 2024-03-06 19:05:33.202908 [INFO] mod_dialplan_xml.c:637 Processing 1000 1000-010086 in context default 2024-03-06 19:05:33.202908 [NOTICE] switch_channel.c:1104 New Channel sofia/external/10086 [901fb9b0-35c9-4ea6-a4a4-3407e2937483] 2024-03-06 19:05:52.623019 [NOTICE] sofia.c:7156 Ring-Ready sofia/external/10086!

我们可以从FreeSWITCH Console里面根据这些关键词比如Invite就是New Channel 180 Ringing就是对应Ring-Ready200 OK就是对应就是对应has been answered来看呼叫进展情况。 再配合dialplan信息就可以理解到FreeSWITCH如何处理呼叫的了。 比如我们看下面这句日志 2024-03-06 19:11:12.373308 [INFO] mod_dialplan_xml.c:637 Processing 18719289062 18719289062-5551212 in context public mod_dialplan_xml 就是执行dialplan对应的就是freeswitch/conf/dialplan下面的文件。根据主叫和被叫号码来匹配业务流程5551212这个被叫号码很多文档里会把这个叫做DID有一个默认流程文件名是00_inbound_did.xml 我们把这个xml文件内容贴在下面
includeextension namepublic_didcondition fielddestination_number expression^(5551212)$!--If youre hosting multiple domains you will want to set thetarget_domain on these calls so they hit the proper domain after youtransfer the caller into the default context. $${domain} is the default domain set from vars.xml but you can set itto any domain you have setup in your user directory.-- action applicationset datadomain_name$${domain}/!-- This example maps the DID 5551212 to ring 1000 in the default context --action applicationtransfer data1000 XML default//condition/extension
/include这个文档有助于您更快捷的了解呼叫信令流程、电话业务处理流程。对于想深入了解SIP信令的同学来说也可以把SIP debug打开sofia loglevel all 9就能看到详细的信令过程。
