I am new to Kamailio.  I’ve got the Carrier Route module up and running, but I’d like to match on scan_prefix length and not just the scan_prefix digits.  Stated a little differently, I would like to define the scan_prefix and how many digits to expect after the scan_prefix.  I am hoping that wildcards are supported in the scan_prefix field or is there another way to do this? 

Thanks,

Tyler
