Hello,
as far as I can remember, sending a redirect 3xx response takes in
consideration any new request URI, which is added as contact. Now, not
sure why the second parameter of get_contacts() would influence that, no
much time to look at the code.
But, meanwhile, can you try with revert_uri() instead of:
$ru = "sip:" + $rU + "@sip.wlvoip.net";
Cheers,
Daniel
