Hello,
Kamailio is not receiving the BYE request when the call is ended by any of
call parties.
Noting that when the call is connected, a direct RTP session is established
between the user and the gateway , and kamailio doesn't receive since then
any message related to this call.
Is there any trick to do in order to let kamailio gets the BYE request?
Attached is the used configuration.
Appreciate your help.
Regards,
Ali

Hi Ali,
Why is Kamailio not receiving the BYE? Is it not coming through the network (as determined
by a packet capture off the wire)? Or is it not being correctly processed, as for example
because the request is somehow malformed?
The configuration alone will not illuminate this. Packet captures are needed for
diagnosis.

Hi Ali,
I was unable to open your client trace, but the Kamailio trace worked:
client-trace.pcap: pcap-ng capture file - version 1.0
kamailio trace.pcap: data
Anyway, looking at the Kamailio trace, you will see that the BYE is
going straight from 192.168.26.3 (client) to 192.168.26.4 (gateway),
bypassing Kamailio.
This is the normal, default behaviour for a proxy. A BYE is a kind of
request called a sequential request, which means it occurs within a
dialog. After the initial INVITE transaction is set up through the
proxy, sequential requests such as end-to-end ACKs, BYEs, reinvites,
etc. flow directly between the endpoints, using the network and
transport-layer reachability information in their respective Contact
headers.
If you want these sequential requests to traverse Kamailio, you must add
a Record-Route header to the initial INVITE before forwarding it. This
tells the two endpoints to pass sequential requests through Kamailio as
well:
if(is_method("INVITE")) {
...
record_route();
...
if(!t_relay())
sl_reply_error();
}

Hi,
When I'm adding record_route() to kamailio config , Acks and BYE messages
are received by kamailio , yet connection between the client and the gateway
is not properly established meaning that the gateway keeps waiting for
acknowledgement and then network failure message appear.
Below is the status of SIP phone on the gateway side :
Session ID: 67
Session Type: SIP
Call Type: SIP
Direction: Incoming
Address: 192.168.110.181 : 5060
Dial String: sip:5000@192.168.110.181
Dialed as:
Respondent: 5000
Program: X-Lite
Program version:
Status: Awaiting acknowledgement
Audio codec (in) :
Audio codec (out): PCMU

Ali

The ACK is stopping at Kamailio.
Be sure that you have loose_route management in kamailio script and that
the ACK is hitting it.
Something like
if (loose_route()) {
xlog("L_ERR", "route[MAIN]: call-id=$ci from=$fU to=$tU : attempt
to route with preloaded Routes");
if (is_method("ACK"))
t_relay();
exit;

The BYE is an in-dialog message, so it should be routed in the same

Hi,
in the INVITE going to the client there is no Record-Route header.
This means that the in-dilaog messages won't go through kamailio. In the
trace you are also missing the ACK for the INVITE for the same reason.
Be sure that in your kamailio script you are calling record_route().

Federico

Hello,
Kamailio is not receiving the BYE request when the call is ended by any of

Noting that when the call is connected, a direct RTP session is

since then any message related to this call.
Is there any trick to do in order to let kamailio gets the BYE request?
Attached is the used configuration.
Appreciate your help.
