我的问题是如何在拨号计划中动态获取当前呼叫端口的组号。
例如,如果用户呼叫端口 1 中的 pri,那么我的拨号语句是
exten => _X.,n,dial(DAHDI/g1/${NUMBER})
对于第二个 pri 端口 2 上的呼叫
exten => _X.,n,dial(DAHDI/g2/${NUMBER})
g3、g4、g5 等用于其他端口,以便设置特定的 DID
当前,当来电时我正在做什么,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} )} : ${GROUP} )})
对于其他组,等等,对于拨号,我这样做
exten => _X.,n,dial(DAHDI/${GROUP}/${NUMBER})
但我不认为这是一个好主意,因为我有 8 个端口,所以我必须编写 8 行来确定组并通过匹配 DID 进行拨号。那么有没有什么方法可以在我的拨号计划中动态获取组意味着是否有任何通道变量我可以得到当前呼入端口呼叫的组吗?
