You can redirect the REGISTER request to the 2nd server. SER-1 receives a REGISTER and processes it with save_noreply(). It then redirects the REGISTER method to the 2nd server using sl_send_reply("301", "Moved Permamently"); The 2nd server will detect that the REGISTER has been redirected and will generate 200 OK (a parameter in the request-uri could be used for the detection).
the detection part could possibly be done without any r-uri params as follows: before updating contact in db location table and generating 301, ser checks from db if contact has been updated "recently" and if so it would only do memory update and would not generate 301.
