You need to call nat_keepalive() on the border server that's the entry
point, not later.
Phone -> Pa -> Pb -> Pc -> Destination
Pa needs to call nat_keepalive() in the above example, not Pb nor Pc.
Also call it the first time the SIP message enters the proxy, not
later after you maybe looped the message through the proxy and it
comes from itself.
