freeswitch的拨号规则配置

来源：互联网发布：淘宝闲鱼手机版网页编辑：程序博客网时间：2024/04/28 00:57

当一个呼叫在ROUTING状态下达到命中拨号规则解析器时，相应的拨号规则就开始解析了。随着解析的进行，在xml文件中的符合条件的或标签中的指令形成一个指令表，安装到这个通道中。

你可以将拨号规则文件放到conf/dialplan/default下，这个目录下的拨号规则要比enum拨号规则优先处理。这个目录下的文件执行优先级是按其文件名开头的数字排序（由小到大），最大的那个文件是99999_enum.xml，这个文件捕捉所以的呼叫，所以我们自己定义的文件一定要小于这个文件才可能被先执行。一个以字母开头的文件名会大小999999_enum.xml。

可以通过${api func(api arg ${var_name})}的方式调用一个模块的函数。

通常一个拨号规则文件会包括三个要素：context, extension, condition和action。这些项目会被依次处理，只到达到action。

context

context是一个extension的逻辑组，一个context可以包含一个或多个extension。

context有一个name参数，any是一个保留的name参数值，它代表任何context。name用来标识一个context。在freeswitch.xml的dialplan section中可以有多个context。

extension

extension就是一个呼叫的目标。它有一个name，一些condition和action，这些东西会告诉freeswitch应该做什么。

语法：

<span class="kwrd"><</span><span class="html">extension</span> <span class="attr">name</span><span class="kwrd">="{exten_name}"</span> [<span class="attr">continue</span><span class="kwrd">="[true|false]"</span>]<span class="kwrd">></span>

name参数是必须的，它是extension的唯一标识。

另外还有一个可选的参数continue，如果它配置为true的话，即使这个extension已经匹配，在执行完它的action后，还会继续执行后序的extension。其默认值为false。

{exten_name}可以是任何值。有一种特殊情况，如果exten_name正好与destination_number相等的话，解析器会从这个extension开始解析。但这是意味着就会执行它（执行要看它里面的condition）。如果没有这一特殊情况，解析器会从第一个extension开始解析。

如果condition中的field与expression匹配，再执行condition中的action。此时如果expresion中的以()括起来的值话，$1,$2,…,$N会依次得到这些值。在action中的data可以使用这些变量。

如果没有匹配成功，则会执行中的指令。此时，因为没有匹配，所以$1,$2等是没有值的。

condition中除了field和expression参数外，还可以有一个break参数，这个参数指明什么情况下中断这个extension的条件匹配。也就是说extension在什么情况下在这个condition中止查询，这个condition后面的condition不在执行了。

break的值可以是：

‘on-true’ : 如果这个匹配成功，则下面的condition不再查询
‘on-false’: 如果这个匹配失败，则…… (这个是默认值) 。也就是说，默认的情况下，只要有一个condition匹配失败了，这个extension也就不再往下执行了，再换它下面的extension。
‘always’ : 总是在此处停止
‘never’ : 永远不在此处停止

<span class="kwrd"><</span><span class="html">extension</span><span class="kwrd">></span>  <span class="rem"><!-- destination_number是freeswitch的内部变量 --></span>  <span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span><span class="kwrd">="destination_number"</span> <span class="attr">expression</span><span class="kwrd">="^500$"</span><span class="kwrd">></span>     <span class="rem"><!-- 这是在本地注册用户里找500，用%，后面的x.x.x.x是freeswitch服务器的ip --></span>     <span class="kwrd"><</span><span class="html">action</span> <span class="attr">application</span><span class="kwrd">="bridge"</span> <span class="attr">data</span><span class="kwrd">="sofia/profilename/500%x.x.x.x"</span><span class="kwrd">/></span>     <span class="rem"><!-- 这是在不在本地找用户，而是直接桥接到一个指定的sip uri，用@, x.x.x.x是sip uri的地址 --></span>     <span class="rem"><!-- <action application="bridge" data="sofia/profilename/500@x.x.x.x"/> --></span>  <span class="kwrd"><!--</span--><span class="html">condistion</span><span class="kwrd">></span><span class="kwrd"><!--</span--><span class="html">extension</span><span class="kwrd">></span></span></span>

示例2，通过网关呼叫用户：

<span class="kwrd"><</span><span class="html">extension</span> <span class="attr">name</span><span class="kwrd">="testing"</span><span class="kwrd">></span>   <span class="rem"><!-- expression里的(100)就设置了$1为100 --></span>  <span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span><span class="kwrd">="destination_number"</span> <span class="attr">expression</span><span class="kwrd">="^(100)$"</span><span class="kwrd">></span>    <span class="rem"><!-- gateway是mod_sofiar的一个关键字，指就是网关。"gw"就是这个网关的名字。 --></span>    <span class="kwrd"><</span><span class="html">action</span> <span class="attr">application</span><span class="kwrd">="bridge"</span> <span class="attr">data</span><span class="kwrd">="sofia/gateway/gw/$1"</span><span class="kwrd">/></span>  <span class="kwrd"><!--</span--><span class="html">condition</span><span class="kwrd">></span><span class="kwrd"><!--</span--><span class="html">extension</span><span class="kwrd">></span></span></span>

condition

condition就是决定当然呼叫是否要在这个extension中处理的一个模式匹配标签。

语法：

<span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span><span class="kwrd">="[{field_name}|${variable_name}|${api_func(api_args ${var_name})}]"</span> <span class="attr">expression</span><span class="kwrd">="{expression}"</span> <span class="attr">break</span><span class="kwrd">="[on-true|on-false|always|never]"</span><span class="kwrd">></span>   <span class="kwrd"><</span><span class="html">action</span> <span class="attr">application</span><span class="kwrd">="app name"</span> <span class="attr">data</span><span class="kwrd">="app arg"</span><span class="kwrd">/></span>   <span class="kwrd"><</span><span class="html">anti-action</span> <span class="attr">application</span><span class="kwrd">="app name"</span> <span class="attr">data</span><span class="kwrd">="app arg"</span><span class="kwrd">/></span><span class="kwrd"><!--</span--><span class="html">condition</span><span class="kwrd">></span></span>

fileld和expression是必须的,break是可选的。

有一些内部变量可以用：

context Why can we use the context as a field? Give us examples of usages please.
rdnis Redirected Number, the directory number to which the call was last presented.
destination_number Called Number, the number this call is trying to reach (within a given context)
dialplan Name of the dialplan module that are used, the name is provided by each dialplan module. Example: XML
caller_id_name Name of the caller (provided by the User Agent that has called us).
caller_id_number Directory Number of the party who called (caller) -- can be masked (hidden)
ani Automatic Number Identification, the number of the calling party (caller) -- cannot be masked
aniii The type of device placing the call ANI2
uuid Unique identifier of the current call? (looks like a GUID)
source Name of the FreeSWITCH module that received the call (e.g. PortAudio)
chan_name Name of the current channel (Example: PortAudio/1234). Give us examples when this one can be used.
network_addr IP address of the signaling source for a VoIP call.
year Calendar year, 0-9999
yday Day of year, 1-366
mon Month, 1-12 (Jan = 1, etc.)
mday Day of month, 1-31
week Week of year, 1-53
mweek Week of month, 1-6
wday Day of week, 1-7 (Sun = 1, Mon = 2, etc.)
hour Hour, 0-23
minute Minute (of the hour), 0-59
minute-of-day Minute of the day, (1-1440) (midnight = 1, 1am = 60, noon = 720, etc.)

除了上面的变量外，还可以使用自定义的变量${variable}，以及一些api函数${api(args)}

这些变量可以在field及expression里。

condition是不能嵌套的，但可以将多个condition堆在一起，并设置break为on-false（默认值），这样的效果与嵌套一样。

示例1，利用cond API函数：

<span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span>="${<span class="attr">cond</span>(${<span class="attr">my_var</span>} <span class="kwrd">></span> 12 ? YES : NO)}" expression="^YES$"<span class="kwrd">></span>    <span class="kwrd"><</span><span class="html">action</span> <span class="attr">application</span><span class="kwrd">="log"</span> <span class="attr">data</span><span class="kwrd">="INFO ${my_var} is indeed greater than 12"</span><span class="kwrd">/></span>    <span class="kwrd"><</span><span class="html">anti-action</span> <span class="attr">application</span><span class="kwrd">="log"</span> <span class="attr">data</span><span class="kwrd">="INFO ${my_var} is not greater than 12"</span><span class="kwrd">/></span><span class="kwrd"><!--</span--><span class="html">condition</span><span class="kwrd">></span></span>

示例2，嵌套效果：

<span class="kwrd"><</span><span class="html">extension</span> <span class="attr">name</span><span class="kwrd">="To PSTN"</span><span class="kwrd">></span>  <span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span><span class="kwrd">="fdnis"</span> <span class="attr">expression</span><span class="kwrd">="9541231234"</span><span class="kwrd">/></span>   <span class="kwrd"><</span><span class="html">condition</span> <span class="attr">field</span><span class="kwrd">="destination_number"</span> <span class="attr">expression</span><span class="kwrd">="(.*)"</span><span class="kwrd">></span>     <span class="rem"><!-- 一个网关注册到fs, x.x.x.x就是这个网关的地址，5061是它的sip协议端口。但这里为什么没有用gateway关键字呢？ --></span>      <span class="kwrd"><</span><span class="html">action</span> <span class="attr">application</span><span class="kwrd">="bridge"</span> <span class="attr">data</span><span class="kwrd">="sofia/profilename/$1@x.x.x.x:5061"</span><span class="kwrd">/></span>   <span class="kwrd"><!--</span--><span class="html">condition</span><span class="kwrd">></span><span class="kwrd"><!--</span--><span class="html">extension</span><span class="kwrd">></span></span></span>

action

action是在condition匹配的时候执行，而anti-action是在condition不匹配的时候执行。

action有两个参数，一个是application，一个是data。其中application是指一个注册的应用程序。data是给这个应用程序传递的参数。

在anti-action里不能使用$1这样的变量，原因是expression没有匹配成功，所以$1没有值。

内联action

先说说hunting和executing，hunting就是freeswitch扫描符合条件action放到一个队列里，executing就是执行队列里的action。

所以，在通常情况下freeswitch中的hunting和executing是分两步执行的。这说意味着在executing时设置的变量，在hunting时是不可用的。也就是说，即使我们能用可以显示变量的值，但是在我们的xml文件中的condition中可能是不可用的。

要解决这个问题就要用到inline参数。

<action inline="true" application="set" data="some_var=some_val"/>

action的参数inline设置为"true"时，action会在hunting时执行。这样，后面的condition就可以使用这个${some_var}变量了。

另外，用inline方式执行的application不能显示在cdr里，原因是它们在hunting时就已经执行了。

不是所有的application都可以在hunting时执行。只有那些快速执行get或set变量值，且不会影响当前session的application才可以。它们包括下面这些：

check_acl,
eval,
event,
export,
log,
presence,
set,
set_global,
set_profile_var,
set_user,
sleep,
unset,
verbose_events,
cidlookup,
curl,
easyroute,
enum,
lcr,
nibblebill,
odbc_query

SIP特定的拨号字符串

呼叫一个SIP URI

基本语法：sofia/my_profile/user@host, 如：

sofia/my_profile/1234@192.168.1.1

呼叫一个注册用户

没有注册别名的情况：sofia/my_profile/1234%mydomain.com

注册别名的情况：sofia/mydomain.com/1234，注意：这里没有显示指定profile文件。也可以这样：user/1234@mydomain.com

通过网关呼叫

sofia/gateway/mygateway.com/1234

其中网关名就是mygateway.com，呼叫的用户1234

呼叫时指定传输协议

传输协议可以是：TCP, UDP, TLS, SCTP，如：

sofia/my_profile/1234@192.168.0.1;transport=tcp

指定编解码

{absolute_codec_string=XXXX}sofia/my_profile/user@your.domain.com

Getting Fancy With PortAudio，这个没搞明白是做什么用的

If you have PortAudio running and would like to specify the codec you need to originate first and bridge second:

originate {absolute_codec_string=XXXX}sofia/default/foo@bar.com bridge:portaudio/auto_answer inline

修改SIP联系人

fs正常会用mod_sofia@ip:port做为内部的联系人，如果想修改一下，

{sip_contact_user=foo}sofia/my_profile/1234@192.168.0.1;transport=tcp

使用定制的SIP URI

比如，要发送在“SIP：”开头的URI，

sofia/my_profile/sip:xxxx;phone-context=cdp.udp@somedomain.com;user=phone
