Opppsss.... I think that You make a little typo.... Wouldn't the correct be "^sip:1[0-9]{8}@" to match all numbers with 9 digits initiated by an '1' and followed by any combination of digits (from '0' to '9')?

I have an expression like this: if(uri=~"^sip:1[0-9]*@) This matches numbers like 15552221212, but also matches number like 15552221212#. when i make it as: if(uri=~"^sip:1[0-9]@*) Use this if (uri=~"^sip:1{8}[0-9]@" ) Again this matches any special characters after the number. I just wanted a regular expression that will match only numbers and no alphabets or special characters. Can someone please help me to formulate a regular expression for this.
