The above is incorrent, you cannot do "avp(s:$rU), it makes no sense. An AVP 
must have an intenger or string identifier:

  avp(s:name1)
  avp(s:name1)
  avp(i:1)
  avp(i:2)

But you cannot do:

  avp(s:$rU)  <-- Why it???


Anyway what I mean is that if you have modified RURI (maybe using 
alias_db_lookup, lookup('location')...) you still can get the 
**original**RURI via $ou, $oU... variables.

Example:

-------
RURI = sip:boby at domain.com

alias_db_lookup();
# Now RURI => 201 at domain.com

$ou => sip:boby at domain.com

lookup('location');
# Now RURI => 201 at 99.88.100.123:5060

$ou => sip:boby at domain.com
