[OpenSIPS-Users] Does create_dialog behave differently on 1.6 than on 1.7?

[Duane Larson]

Saul,

I did make that one change.  Thanks for the info.

I still have the same issue.  Here is a NGREP of the client registering and
then calling someone.

You will see that all messages to the softphone client are good except for
the OPTIONS keepalive messages.

Here is how the softphone shows up in the location table

Vlad,

In my INVITE route I do my NAT stuff before calling create_dialog()

                if (client_nat_test("7")) {
                        append_hf("P-hint:
route(3)|setflag7,forcerport,fix_contact\r\n");
                        setbflag(7);
                        force_rport();
                        fix_nated_contact();
                };


and then further down the script I do

create_dialog("PpB");

I'm not saying this is a bug because its very possible I have something
misconfigured.  Would just like to figure out what is wrong.
