It depends upon how "redundant" the cluster actually is.  If fully redundant, 
an ACK or PRACK received on one server can stop response retries on the other.  

Similarly rfc3263 section 5, allows responses to "forked" upon failure to 
deliver.  If a proxy/UAC truly that redundant, a response received on one 
server can stop request retries on the other.

Concerning ACK and PRACK, usually never unless truly that flexible.  Concerning 
other requests, it may or may not prefer it but might allow it.
