我的问题是如何在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，那么我的拨号语句是
For example if user call to the pri which is in port 1 then my dial statement is
exten => _X.,n,dial(DAHDI/g1/${NUMBER})
对于第二个 pri 端口 2 的呼叫
And for the call on second pri port 2
exten => _X.,n,dial(DAHDI/g2/${NUMBER})
g3,g4,g5 等用于其他端口以设置该特定 DID
g3,g4,g5 etc for other ports in order to set that particular DID
当前我在打电话时正在做的事情我创建了一个 GROUP 变量，它通过检查 DID 范围来存储组
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} )} : ${GROUP} )})
等其他组，拨号我做
exten => _X.,n,dial(DAHDI/${GROUP}/${NUMBER})
但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.所以有没有办法在我的拨号计划中动态获取组意味着如果有的话可以从中获取当前传入端口呼叫组的通道变量?
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
据我所知，DAHDI 组没有这样的变量.
As I know there are no such variables for that DAHDI groups.
在您的 chan_dahdi.conf 中，您使用相同的选项context=from-pstn"，因此您可以轻松地为第 1 组设置context=pri-g1"(第 2 组的context=pri-g2"等)然后在拨号方案中定义类似的东西:
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)
设置起来不像有通道变量那么方便，但对星号来说很快.
It is not as convenient for setting up as if there were channel variables, but fast for asterisk.
请注意，在 [pri-g#] 中的 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.
