### Description
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
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
ds_select("BACKENDS","0");
while(ds_set_dst()) {
xlog("L_DBG",">>> BACKEND du=$du\n");
$uac_req(ruri)="sip:" + $(du{uri.host});
$uac_req(furi)="sip:" + $avp(username) + "@" + $(du{uri.host});
$uac_req(turi)=$uac_req(furi);
uac_req_send();
ds_next_dst();
}
#### Reproduction
<!--
If the issue can be reproduced, describe how it can be done.
-->
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

when using sdp module to parse sdp I noticed that function called from sdp_get return -1 when no m-lines are present in sdp , normally we should accept sdp without m -line because it can be at a later time through a modified offer , how can we accept such sdp without changing source code for function "parse_sdp_session"

Hey there!
I hope the Kamailio team is physically as well as mentally healthy and thriving towards progressive development.
I am a part of a team which deals in development of converged 4G and 5G networks.
We have been diving deep into Open5GS 5G core and use Kamailio as our SIP server.
However, we are trying to successfully implement VoNR UE registration as well as calling, and facing challenges in that area.
I recently saw the VoNR as well as SMSoNR demonstration which the Kamailio team …
[View More]performed and was massively impressed by it! I would like to know when will the N5 SBI update will be rolling out to the public so that we can conduct our testing as well.
Hoping for a timely response and update,
Thanks and regards,
Vaibhav.

### Description
The uri parser seems to fail in multiple ways on username-parameters. The ways it fails depends on the presence of user-params in the incoming request and on adjustments to $ru, $rd and $rU in the script.
My expectation is that the whole username, including user-params is *always* visible in $rU. In reality, the user-params are absent or present depending on manipulations to the uri in the script.
When setting $rU to a value with a user-param, that user-param is represented when reading $ru, but not in $rU.

I used below config script to test various scenario's.

```
This one fails in an interesting way. The incoming uri has a user-param. When overwriting $rU with a user-param, the user-param from the incoming request is kept in addition to the new one instead of being overwritten. $rU still misses (both) user-params.

I have no build (yet) with EXTRA_DEBUG enabled.

#### 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:

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

The sipcapture module actually uses the DEFAULT_DB_URL instead of "no database at all". When you do not set the parameter, the module will try to connect to the default db. [See source code of parameter](https://github.com/volkland/kamailio/blob/74361cdeacee8864216d30….
