Hi All, when i use this regular expression in my lua script to validate the number i get. local number = session:playAndGetDigits(0, 20, 1, tryTimeOut, "#", promptFile, errorFile, "^\+(1|2[1-689]\d|2[07]|3[0-469]|3[578]\d|4[0-13-9]|42\d|5[09]\d|5[1-8]|6[0-6]|6[7-9]\d|7|8[035789]\d|8[1246]|9[0-58]|9[679]\d)(\d+)") playAndGetDigits does not recognize # as terminator - terminators = digits used to end input if less than <max> digits have been pressed. (Typically '#') example when i Dial this number followed by the pound key: 972525777777# the method plays the error file. Thanks, Snabel
