My idea is…
…if incoming call recive then DID-Trunk separates SIP header. Thats ok and working…but what I need to do is that I want make number shorter only 3 last digits. Right now its 7 digits. Can anybody knows the simple solution to my problem…
Here is my extensions.conf
[DID-Trunk]
exten => s,1,Noop(Fixing DID using information from SIP TO header)
exten => s,2,Set(BNUM=${CUT(CUT(SIP_HEADER(To),@,1),+,2)})
;exten => s,2,Set(BNUM=${CUT(CUT(SIP_HEADER(To)|@|1)|:|2)},1)
exten => s,3,Noop(${BNUM})
exten => s,4,Set(CNUM=${CUT(BNUM,2,2-)})
exten => s,5,Noop(${CNUM})
exten => s,6,Goto(accounts,${CNUM},1)
;;;;;;;;;;;;;;;;;;;; MAIN EXTENSIONS (PEERS) ;;;;;;;;;;;;;;;;;;;;;
[accounts]
exten => _44991XX,1,Dial(SIP/170,10)
exten => _44991XX,2,Dial(SIP/171,20)
returns a substring of the string foo, beginning at offset offset and returning the next length characters. The first character is at offset 0.
* If offset is negative, it is taken leftwards from the right hand end of the string.
* If length is omitted or is negative, then all the rest of the string beginning at offset is returned.
Examples:
${123456789:1} - returns the string 23456789
${123456789:-4} - returns the string 6789
${123456789:0:3} - returns the string 123
${123456789:2:3} - returns the string 345
${123456789:-4:3} - returns the string 678
Examples of use:
exten => _NXX.,1,SetVar(areacode=${EXTEN:0:3}) - get the first 3 digits of ${EXTEN}
exten => _516XXXXXXX,1,Dial(${EXTEN:3}) - get all but the first 3 digits of ${EXTEN}
exten => 100,1,SetVar(whichVowel=4)
exten => 100,2,SetVar(foo=AEIOU:${whichVowel}:1) - sets ${foo} to the single letter ‘U’ [/code]
It might be. But that book is not an online resource I could point to.
It might be more helpful, if instead of pointing at a page on a book that some people might not have, you post a brief description of what is on that page. Otherwise we may as well write something like: “The answer is written on the back of this napkin on my desk.”
I’m not trying to start a flame war here, I’m just trying to highlight how that sort of comment may not be as constructive as you may have intended it to be.
