[Serusers] What can replace "nat_uac_test" for ser-0.8.12

[gg]

Hi everyone:
   Because I couldn't find the RPM package SER-0.8.14
for linux, and the mysql supported package. I have
installed SER-0.8.12. But there is no "ping_nated_only"
and "nat_uac_test" in module nathelper . To judge whether
the client is behind NAT, How can I do?
   Anyone help me please!
   thank you!
