Hello Andrew,
the error below is from the config, that it can't resolve the
sip.example.com domain. You need to replace this domain with a domain that you own, or use IP
addresses.
Best regards,
Henning
Here’s the bash history for anyone curious:
1 yum install -y gcc gcc-c++ bison flex make ruby-devel git
2 git clone https://github.com/kamailio/kamailio.git
3 cd kamailio/
4 make include_modules="app_ruby" cfg
5 make all && make install
6 cd /usr/local/etc/kamailio/
7 ls
8 vim kamailio.cfg
9 vim /etc/systemd/system/multi-user.target.wants/kamailio.service
10 systemctl daemon-reload
11 systemctl start kamailio
12 tail -f /var/log/messages
13 ls
14 mkdir /usr/local/etc/kamailio/dbtext
15 cd /usr/local/etc/kamailio/dbtext
16 ls
17 vim uacreg

If anyone can help find the issue I’d be very interested, however it looks
like issue is package/config somewhere rather than kamailio.
Thanks

Update:
I’ve just tried the config from the GitHub issue on another server (CentOS

This looks to me like it is attempting registration and failing.
I’ve tried this same config on my main server (Amazon Linux 2) and am not
getting any such messages.

I’m assuming we’re missing a package, a socket definition varies,
something like that. How can I further debug this?
Thanks!

Thanks so much Miko!
You’re completely right. This is also in the docs for the module, it
appears I’ve skimmed over that part!
It appears the DB is now loading without error, however I don’t see any
attempting for registration in Wireshark. A kamcmd uac.reg_dump doesn’t
return any result.
I’ve copied config shown to be working from a GitHub issue on an
unrelated problem (https://github.com/kamailio/kamailio/issues/936
<https://github.com/kamailio/kamailio/issues/936>). Relevant lines
below:
#!define DBURL "text:///etc/kamailio/dbtext
<text:///etc/kamailio/dbtext>"
modparam("rr", "append_fromtag", 1)
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "track_cseq_updates", 1)
modparam("uac", "restore_dlg", 1)
modparam("uac", "reg_db_url", DBURL)
modparam("uac", "reg_timer_interval", 60)
modparam("uac", "reg_retry_interval", 60)
modparam("uac", "reg_contact_addr", "1.2.3.4:5060")
And /etc/kamailio/dbtext/uacreg:
l_uuid(string) l_username(string) l_domain(string) r_username(string)
r_domain(string) realm(string) auth_username(string)
auth_password(string) auth_proxy(string) expires(int) flags(int)
reg_delay(int) 12345678:user:domain.local:11111111:sip.example.org
<http://sip.example.org/>:sip.example.org
<http://sip.example.org/>:11111111:XXXXXXXXXXXXXXXX:sip\:sip.example.org
:600 <http://sip.example.org:600/>:0:0
Both an lsof and a WITH_DEBUG show uac.so is being loaded without issue,
however no messages relevant to registration are showing, and no
REGISTER messages appear in Wireshark.
A kamcmd to query the record shows it does not appear loaded:
[root@ip-10-0-0-2 kamailio]# kamcmd uac.reg_info l_uuid 12345678
error: 404 - Record not found
I feel like I’m missing something obvious here!

I’m currently playing with the UAC module to hand off remote
registrations with trunks to Kamailio.
I want to keep Kamailio’s external connections low, so I’m planning to
use db_text to load the UAC info, and populate the flat file via other
methods.
When attempting to load my UAC DB via db_text however, I get the
following:
Mar 26 04:59:30 ip-10-0-0-2 /usr/local/sbin/kamailio[31904]: ERROR:

.
.
.
2) Why is my db_text failing to load the file?
Hi
I think your db_url should point to directory instead of file.
Here is one working example using other modules:
---
modparam("mtree", "db_url", "text:///opt/stuff/cfg/db_text
<text:///opt/stuff/cfg/db_text>") modparam("htable", "db_url",
"text:///opt/stuff/cfg/db_text <text:///opt/stuff/cfg/db_text>") ---
In directory /opt/stuff/cfg/db_text I have files "htable", "mtrees" and
"version":
---
$ cat version
htable:2
mtrees:2
$ cat mtrees
id(int,auto) tname(string) tprefix(string) tvalue(string)
1:uni:3581234567:24
$ cat htable
id(int,auto) key_name(string) key_type(int) value_type(int)
key_value(string)
0:3581234567\:\:timerc:0:1:30
