[Serusers] MEdiaproxy unable to resolve private IP to public IP

Hi, I m using ser-0.9.0 with mediaproxy, non natted clients can talk fine, but natted clients’ addresses are not resolved to public addresses.Also, the culprit I suppose is a function fix_nated_register() used in the ser.cfg which was not recognized by ser. The relevant code from ser.cfg is as follows: ... ... # ----------------------------------------------------------------- # REGISTER Message Handler # ---------------------------------------------------------------- sl_send_reply("100", "Trying"); if (!search("^Contact:\ +\*") && client_nat_test("7")) { setflag(6); # I commented the following line since it was not recognized by ser # fix_nated_register(); force_rport(); }; ... ...
