Dear all
I followed tutorial from SER-Getting Start document for Mediaproxy to solve nat problem. I read on the Openser document http://www.openser.org/docs/modules/1.2.x/usrloc.html#AEN83 I have to use modparam("usrloc", "nat_bflag", 6) instead of modparam("registrar", "nat_flag", 6)
And from the documentation, it said "When SIP clients attempt to REGISTER with our SIP proxy we need a way to tell the registrar module to store NAT information for any particular UA. We do this by using flag 6, which has been arbitrarily chosen (but defined earlier in the loadmodule parameter section). We could have specified another integer here, but flag 6 seems to be the accepted standard for nat_flag.
If the nat_flag is set before calling the save() function to store contact information, SER will preserve the NAT contact information as well as set the flags column in the MySQL location table. By doing so, we can call lookup(location) when processing messages and flag 6 will be set for NATed clients."
I have a NAT UA is detected as NAT-ed UA by Openser with below rule and do setflag(6); before it does save("location");
Why in mysql, location table, i see the flags column still 0 instead of 6 ?
Did I miss something? Please help :(
