替换星号拨号方案中的字符 [英] Replace characters in Asterisk Dialplan

问题描述

我想为 A 和 P 更改几个关闭字符 * # 以使监视器文件名的字符更友好.我能找到的唯一解决方案是在拨号计划中自己做，但它会产生很多冗长的输出，并且没有我想要的那样高效(快速).我会把它贴在这里以防万一有人想使用它.但我正在寻找一个星号函数，我可以编译一些我可以使用拨号计划调用的东西，比如 ${REPLACE(${EXTEN},*,a)} 并转换了 exten **123**456***到 AA123AA456AAA.

I want to change a couple off characters * # for A and P to have the monitor filename with characters more friendly. The only solution I could find was to do it my self within the dialplan but it generates a lot of verbosity output and is not as efficient(fast) as I would like to. I'll post it here just in case someone wants to use it. But I'm looking for an asterisk function that I can compile something that I can call withing the dialplan like ${REPLACE(${EXTEN},*,a)} and have the exten **123**456*** converted to AA123AA456AAA.

exten => s,n,Set(pre=)
exten => s,n,GotoIf($["${i}" = "0"]?post)
exten => s,n,Set(pre=${str:0:${i}})
exten => s,n(post),Set(post=)
exten => s,n,GotoIf($["${i}" = $[${length} - 1]]?write)
exten => s,n,Set(post=${str:$[${i} + 1]})
exten => s,n(write),Set(str=${pre}${replace}${post})
exten => s,n(continue),Set(i=$[${i} + 1])
exten => s,n,EndWhile
exten => s,n,Set(REPLACERESULT=${str})

推荐答案

REPLACE() 函数现在可以轻松做到这一点:

The REPLACE() function now does this easily:

exten => 100,1,Set(find=**123**456***)
same => n,NoOp(find=${find})
same => n,Set(replace=${REPLACE(find,*,A)})
same => n,NoOp(find=${find}, replace=${replace})
same => n,hangup()

输出:

*CLI> channel originate local/100@default extension null@default
