Hi
there is an issue with the SIP parser for the t_uac_send function
https://www.kamailio.org/docs/modules/devel/modules/tm.html#tm.f.t_uac_send
If I call this function for example:
t_uac_send("INVITE", "sip:test@123.123.123.123:5060", "", "" ,"Content-Type: text/plain\r\nContact: <sip:85951b3d-096c-95d6-5f05-4f38095aca9f@172.17.64.120:5060;transport=tcp>;+u.sip!devicename.ccm.cisco.com=\"SEP5486BC7F2BBC\"", "Testbody")
Then the resulting request is broken - it's probably due to a character (exclamation mark?) in the Contact header.... I tested it with a call from kemi, but it probably also occurs when you run it with a normal kamailio -script tests

Situation: Two Kamailio nodes syncing dialog profiles via DMQ
Observation: When a dialog timeout is encountered, about half of the time, the timeout is triggered on the peer node not handling the dialog preventing the call to be correctly terminated and also leaving entries in the dialog database which never get deleted.
https://kamailio.org/docs/modules/5.7.x/modules/dialog.html#dialog.p.enable…
Makes clear, that only the node which is handling the dialog in question, can make changes not related to the dialog profiles. So when a dialog times out, it is this node which has to trigger the timeout, not any other one.
When looking at the source code, it is clear, that the 'lifetime' is transmitted via DMQ dialog message to the peer nodes, which in turn arm a timer. So it is obvious, this time will trigger, sometimes before the instance handling the dialog itself triggers that timer.
With some assistance of @oej I found a way to alter the JSON payload to extend the lifetime on the peer nodes:
```
route[DMQ_CAPTURE]
{
if(is_method("KDMQ"))
{
if(has_body("application/json") && $fU == 'dialog')
{
if (jansson_get("lifetime", $rb, "$var(lifetime)"))
{
$var(new_lifetime) = $var(lifetime) + 60; # Add 60 seconds on DMQ peer to make sure it expires AFTER main node.
$var(newrb) = $rb;
jansson_set("integer", "lifetime", $var(new_lifetime), "$var(newrb)");
set_body("$var(newrb)","application/json");
msg_apply_changes();
}
}
dmq_handle_message();
exit;
}
}
```
Testing with this config fixed the issue of the timeout firing on a peer node instead of the node handling the dialog.
Issue is present in 5.5, 5.6 and after looking at the code, I assume also on 5.7

Hi,
I think there is an issue with writing CDRs on failover scenarios.
I have two servers with Kamailio. Both server running Debian 11 (bulleye) and latest Kamailio 5.6.1 from git.
I'm using DMQ to sync dialogs and htable between these servers, so both servers have the same knowledge of dialog state. Both Kamailio uses nobind option, so I can switch a VIP from one server to the other one. This is managed with keepalived. Switching the VIP from one server the other one works fine an while a call is running I can switch the VIP. I can see that the BYE Message is handled OK after I made a switch. I can see that acc is triggered but what is missing is acc_cdr in this case.
I'm using htable to fill all necessary variables to complete the CDR an I can see that all values are synced correctly.
The acc_cdr is created fine if there is no failover so i think it can't be an configuration issue.
Both server holds the same Kamailio configuration except the IP.

### Description
Hi, I ran into an issue where the Kamailio service seemingly froze (didn't crash, but failed to receive and deliver calls) while running, I went through the logs a little bit, and saw the same log pattern (pasted below) recouring every few months or so, on an older installation (5.2.0). Usually, it ended up automatically restarting the service. But not this time, I had to reload it manually to make the service work again.
Is this a known issue?
How can I make sure that the service will be able to restart the next time it happens?
Edward

Hello. I use uac_req_send to send registration to the asterisk pool. If some asterisk did not authorize and re-sent the 401 code, the module causes a kamailio crash
### Troubleshooting

#### Description
I faced an issue with memory leak in case drop NOTIFY messages in the "local-request" event route in `mem_copy_subs` and `build_uac_req`
analysis of mem leak:
kamcmd corex.shm_summary
<code>...

In the code, we have a comment like "never free cbp here because if t_uac_prepare fails, cbp is not freed and thus caller has no chance to discover if it is freed or not", but we'll free the cbp in two cases:
1. in case of error, but we have if (ret == E_DROP) then ret = 0; (so, no error result)
2. in case call insert_tmcb for cbp, but we don't do it for E_DROP
