Calling-Station-Id case sensitive

[lists at justinawilliams.com]

I am not really up  with perl... Is there any way that perl can rewrite
the request and take out either the . or : or - between characters  as
well as make everything lower case?

so that the calling-station-id request would be 00197da6ad06
not 00:19:7d:a6:ad:06  or 00-19-7d-a6-ad-06  or 0019.7da6.ad06


Thanks
