*Hello,*



*Problem:*
In some calls I noticed, OpenSIPS takes at least 1 second to relay BYE
message after calling t_relay function. However, we didn't notice major
time difference in cfg execution before and after calling t_relay.

*Details about Problem:*

route[ON_BYE]
{
    $avp(cdr_call_end_time)=$Ts;
    $avp(cdr_call_end_time_microsecond)=$Tsm;

    xlog("L_WARNING","[ $ci ] Before Do accounting : $Ts:$Tsm");
    launch(radius_send_acct("set2"));
    xlog("L_WARNING","[ $ci ] After Do accounting : $Ts:$Tsm");

    route("DEFAULT_RELAY_ROUTE");
}

route[DEFAULT_RELAY_ROUTE] {
    if (!t_relay()) {
            sl_reply_error();
    }
    exit;
}

In OpenSIPs Log.
Aug 18 13:51:59 OS /usr/local/sbin/opensips[22304]: [ xxx at 1.1.1.1 ] Before
Do accounting : 1503041368:000686
Aug 18 13:51:59 OS /usr/local/sbin/opensips[22304]: [ xxx at 1.1.1.1 ] After
Do accounting : 1503041368:000887

1503041368000887 - 1503041368000686 = 201 usec

OpenSIPs cfg Generate Timestamp : 1503041368000887 and Called t_relay
function.
Timestamp of BYE in tcpdump output: 1503041369001085

1503041369001085 - 1503041368000887 = 1000198

Which means OpenSIPS took 1 second to send BYE to Network Layer.

For more information, I have attached SIP Message text file too.

Looking forward to your help.

Thanks in advance.
