The latest CVS version of openser crashes consistently when trying to
redirect a call.
Below was my original configuration:
modparam("uac_redirect", "default_filter", "accept")
modparam("uac_redirect","acc_function","acc_db_request")
modparam("uac_redirect","acc_db_table","acc")
failure_route[] {
#------------------------------------------
# Moved Temporarily
#------------------------------------------
if (t_check_status("302")) {
get_redirects("*", "Redirected");
t_relay();
return;
};
}
The above configuration produced the following crash. Note that we
added the last DEBUG line in an attempt to isolate what subroutine call
failed.

It appears that there is a failure when calling rd_acc_fct().
I then tested with the setup below:
#modparam("uac_redirect", "default_filter", "accept")
#modparam("uac_redirect","acc_function","acc_db_request")
#modparam("uac_redirect","acc_db_table","acc")
failure_route[] {
#------------------------------------------
# Moved Temporarily
#------------------------------------------
if (t_check_status("302")) {
get_redirects("*", "Redirected");
t_relay();
return;
};
}
Produces this error:
ERROR:acc:acc_log_request: buffer to small
Lastly, I tested with a get_redirect("*") and no error or crash was
produced.
Near the top of my config file, I have the following code:
#-------------
# Accounting
#-------------
if (is_method("BYE|CANCEL")) {
setflag(FLAG_ACC);
setflag(FLAG_ACC_DB);
} else if (is_method("INVITE")) {
setflag(FLAG_ACC);
setflag(FLAG_ACC_DB);
setflag(FLAG_MISSED_CALL);
};
I thought that perhaps the FLAG_ACC_DB wasn't being set correctly in the
failure_route. I added setflag(FLAG_ACC_DB); in the failure_route, just
before the call to get_redirects() and openser still crashed.
While researching this problem, I found that rd_acc_fct is passing 3
parameters while acc/acc.c: acc_db_request is looking for 5 parameters
and acc/acc.c: act_log_request is looking for 4 parameters.
