### Description
When topos is loaded and dialog is configured to timeout a call by sending BYE to each
side, the Route: header is lost and one of the BYEs is not sent to the correct
destination.
This problem does not exist when topos is not loaded.
### Troubleshooting
#### Reproduction
```
modparam("dialog", "rr_param", "dv")
modparam("dialog", "profiles_with_value", "inbound_call ;
outbound_call; timed_call")
modparam("dialog", "dlg_match_mode", 1)
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "send_bye", 1)
modparam("dialog", "timer_procs", 1)
modparam("dialog", "timeout_noreset", 1)
modparam("dialog", "default_timeout", 43200)
$avp(limit) = 15;
dlg_manage();
dlg_set_timeout_by_profile("timed_call", "1",
"$avp(limit)");
dlg_set_timeout($avp(limit));
set_dlg_profile("timed_call", "1");
```

Can you test with master branch (your config for 5.0.x should work) and use debug=3 in
kamailio.cfg? Then attach all logs printed by kamailio when the BYEs are sent out.

From the logs, topos doesn't do anything for any of
the BYEs (as it should, because they are generated by the server). Can you check if the
dialog structures are the same with and without topos? You can dump them via rpc command
once the call is answered -- important to see if record route headers are saved.

You are correct. When topos is loaded, route_set is blank under callee. With no topos
the value does appear there.

I have sent you the logs direct to your gmail address as I don't want to make any

Can you resend as zip or tgz (tar.gz / gz) instead of 7z? These are common formats that
can be unarchived on mobile devices as well.

Started to look at the logs at some point, but got distracted by other tasks ... and with
no much spare time it got delayed. I will try to get back to it asap.

Got some time for it ... according to the logs the route set is seen empty by the dialog
module (you can search for route_set in the logs).
I need more data to troubleshoot:
* grab the pcap with sip packets for such a call
* add following in your config before doing the test.
At the top of request_route block add:
```
xlog("received request from $si with content [[$mb]]\n");
```
At the top of reply_route (add it if you don't have it):
```
xlog("received reply from $si with content [[$mb]]\n");
```
Also add the global parameter:
```
log_prefix="{$mt $hdr(CSeq) $ci} "
```
Put the pcap file and the logs file in a tarball or zip and send it to me.

Interestingly I cannot reproduce the problem with those added lines. If I comment them
out, I can still reproduce the problem. Will experiment a little more but thought I'd
provide that clue.

Just sent you the pcap and log file.
So here's the fun part:
When I add `log_prefix="{$mt $hdr(CSeq) $ci} "` to the global section, the
problem *no longer exists* but when I comment this out, the problem returns.
This seems to be perfectly reliable to fix & break the issue accordingly.
So needless to say the file I sent you does not include the log_prefix, but it does
include the other requested changes.

... thanks for the reminder, it is always good to do it!

Finally back to it, I reviewed a bit based on your hint that issue was not exposed when
`log_prefix` was set and I just pushed a patch to master and 5.0 branches. Can you try and
report if all ok now?

Hi All.
I have just make some tests and now Route header present.
So seems this issue was fixed with Daniel's latest commit.
But I have found one more little issue with topos...
When callee device not reachable kamailio tries to reach it, I have profile with 3 retries
with 1second interval,
But Contact header present only in 1-st Invite. Next Invites are send without Contact
header...
I will send dump with topos and topoh in private e-mail to you Daniel.
Can you look at this issue or better to create a new one in kamailio github?
Thank you.

Hi Daniel,
I think you can close this issue.
For Contact header in retries for initial INVITE I will open new one.
Thank you.
