So:
if(is_method("PRACK|ACK") && !is_present_hf("Contact"))
append_hf("Contact: <sip:$si:$sp;nat=yes>\r\n");
Let me know if works.
Cheers,

Snom use the port from INVITE, mesage not from ASK
Possible it can fix the trouble for other UA. Anyway it's not a common
solution.
Actually, if Cisco is over the port restricted or symmetric nat, without
the port mapping it's not possible to fix it at all.
Thanks Andrew.
