我的问题是如何在我的拨号方案中动态获取当前呼叫端口的组号.
My problem is how can I get the group number of current calling port dynamically in my dialplan.
例如，如果用户调用端口1中的pri，则我的拨号语句为
For example if user call to the pri which is in port 1 then my dial statement is
exten => _X.,n,dial(DAHDI/g1/${NUMBER})
对于第二个pri端口2上的呼叫
And for the call on second pri port 2
exten => _X.,n,dial(DAHDI/g2/${NUMBER})
g3，g4，g5等用于其他端口，以便设置该特定DID
g3,g4,g5 etc for other ports in order to set that particular DID
当前调用时我正在做什么，我通过检查DID范围来创建一个GROUP变量来存储组
Currenty what I am doing when call comes I create a GROUP variable which stores the group by checking DID range
same => n,Set(__GROUP=${IF($[ ${EXTEN} >= ${DIDMINPORT1}]? ${IF($[ ${EXTEN} <= ${DIDMAXPORT1}]?g1:g1)} :g1)})
same => n,Set(__GROUP=${IF($[ ${EXTEN} >= ${DIDMINPORT2}]? ${IF($[ ${EXTEN} <= ${DIDMINPORT2}]?g2: ${GROUP} )} : ${GROUP} )})
对于其他组等，我要拨号
and etc for other groups ,for dialling I do
exten => _X.,n,dial(DAHDI/${GROUP}/${NUMBER})
但是我不认为这是一个好主意，因为我有8个端口，所以我必须写8行来确定组并通过匹配DID进行拨号.所以有什么方法可以在我的Dialplan中动态获取组，这意味着通道变量，我可以从中获取当前传入端口调用的组?
But I dont think its a good idea because I have 8 port so I have to write 8 lines to determine the group and dial by matching the DID.So is there any way to get group dynamically in my dialplan means if there any channel variable from which I can get the group of current incoming port call?
推荐答案
我知道该DAHDI组没有此类变量.
As I know there are no such variables for that DAHDI groups.
在chan_dahdi.conf中，您使用相同的选项"context = from-pstn"，因此可以轻松地为组1设置"context = pri-g1"(为组2等设置"context = pri-g2").然后在拨号计划中定义如下内容:
In your chan_dahdi.conf you use same option "context=from-pstn", so you may easily set "context=pri-g1" for group 1 ("context=pri-g2" for group 2 and etc.) and then define in dialplan something like that:
[pri-main]
exten => s,1,NoOp(Main routine)
[pri-g1]
exten => s,1,Set(PRI_GROUP=1)
exten => s,n,GoTo(pri-main,s,1)
[pri-g2]
exten => s,1,Set(PRI_GROUP=2)
exten => s,n,GoTo(pri-main,s,1)
...
[pri-g8]
exten => s,1,Set(PRI_GROUP=8)
exten => s,n,GoTo(pri-main,s,1)
设置起来似乎不像使用通道变量那样方便，但是对于星号来说却很快.
It is not as convenient for setting up as if there were channel variables, but fast for asterisk.
请注意，在[pri-g#]中，exten可能不是"s"，而是DID号码或其他-但您很快就会在CLI错误中看到它.
Just notice that in [pri-g#] exten may be not "s", but DID number or smth else - but you will see it in CLI errors very soon.
