in radius dictionary SIP-Source-IP-Address is of type ipaddr, which is a
four byte integer.
in order to get source address accounted, $si cannot be used because it
is a string and i haven't found a transformation from ip address string
to int.
is there a solution that i have missed? if not, what would be the best
way to solve this: add a new transformation or a new int valued pv for
source ip address?
