[SR-Users] DBText does not exists!

[Andrew White]

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"

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:sip.example.org:11111111:XXXXXXXXXXXXXXXX:sip\: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 at 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!
