Hi,
I am currently waiting 5 s, but that is just a magic number I do not have
any solid justification.
At first, I though simply waiting for status code of last registration to
be (200 OK) would suffice, but it's not the case:
pjsua_acc_info info;
pjsua_acc_get_info(acc_id, &info);
while (test.status != 200) {
pjsua_acc_get_info(acc_id, &info);
// some usleep()
}
After that I wait for the mentioned 5 s.
ATM I don't have a better solution. I'll get back to you when I finish what
I'm currently working on.
