No.

Let's assume your R-URI is sip:01234100 at some.domain. Your AOR registered 
to OpenSER is sip:01234 at some.domain with a contact sip:01234 at ip, and in 
some circumstances you only want to send sip:100 at ip to the UAC, right?

So you have to extract the extension "100" from the R-URI. Save it into 
a var or an AVP. Your resulting R-URI then is sip:01234 at some.domain. 
Then do a lookup in the location table, which results in an R-URI 
sip:01234 at ip. Then, replace the user-part of the new R-URI with the 
value saved in the AVP or var, so your final R-URI is sip:100 at ip, which 
you can relay to the UAC.
