将组名称添加到星号中的accoding pri端口

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.

例如,如果用户调用端口1中的pri,那么我的dial语句就是

exten => _X.,n,dial(DAHDI/g1/${NUMBER})

而对于第二个pri 2的呼叫

 exten => _X.,n,dial(DAHDI/g2/${NUMBER})

其他端口的g3,g4,g5等,以便设置该特定DID

当我打电话时,我正在做什么我创建一个GROUP变量,通过检查DID范围来存储该组

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,拨打我做

   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行来确定组和拨号匹配DID.So是否有任何方法在我的拨号方案中动态获取组意味着是否有任何通道变量来自我可以获得当前传入端口呼叫的组？

据我所知,DAHDI组没有这样的变量.

在你的chan_dahdi.conf中你使用相同的选项"context = from-pstn",所以你可以轻松地为组1设置"context = pri-g1"(组2的"context = pri-g2"等),然后定义在拨号方案中是这样的:

[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)

设置好像有通道变量一样方便,但对星号来说快.

请注意,在[pri-g#]中,exten可能不是"s",而是DID编号或其他 - 但您很快就会在CLI错误中看到它.
