...stuff before...
exten => _NXXNXXXXXX,n,GoSub(set_cid,1())
...stuff after...
exten => set_cid,1,NoOp()
exten => set_cid,n,Set(CURRENT_CID_LENGTH=${LEN(${CALLERID(num)})})
exten => set_cid,n,GotoIf($[${CURRENT_CID_LENGTH} = 10]?skip_modify_cid)
exten => set_cid,n,While($[${LEN(${CALLERID(num)})} < 10])
exten => set_cid,n,Set(CALLERID(num)=0${CALLERID(num)})
exten => set_cid,n,EndWhile()
exten => set_cid,n(skip_modify_cid),Return()
There is likely a more efficient way of doing that, but I haven't gone through
and looked at the functions to see if there might be a way of avoiding the loop
:)
Also, totally untested, I just wrote it in this email ;)
