Name

StripLSD() — Strips the specified number of trailing (least significant) digits from the current extension

Synopsis

    StripLSD(count)

Strips the trailing count digits from the channel’s associated extension and continues processing at the next priority for the resulting extension. So, for example, if priority 1 of extension 5551212 is StripLSD(4), the last 4 digits will be stripped from 5551212 and the next step executed will be priority 2 of extension 555. If you switch into an extension that has no priority n+1 (where n is the current priority), the PBX will treat it as though the user dialed an invalid extension.

Always returns 0.

This application is deprecated and has been replaced with the substring expression ${EXTEN: X : Y }.

               exten => 5551212,1,StripLSD(4)
    exten => 555,2,SayDigits(${EXTEN})

    ; a better way of doing the same thing
    exten => 5551234,1,SayDigits(${EXTEN::3})
