[SR-Users] Re: Setting up Kamailio as SIP Proxy

[Henning Westerholt via sr-users]

Hello,

the error message about the “db_DBURL not found” is most probably some syntax 
error or missing define on your cfg. The database modules are named db_mysql, 
db_postgres and so on.

Cheers,

Henning

Hey Fred,
I got it working thanks to your example, it is ofc not the exact same 
configuration i needed but it helped to understand more about the UAC module 
and Kamailio in general, it was my first try with it.

Related question, does an error "Module db_DBURL not found" has anything to do 
with the UAC module?
there is also "uac_reg_load_db(): database module not found"

For this test i used Ubuntu (because locally i was using docker in a M1 Mac and 
it was erroring because of the builds available on the debian registry), maybe 
it has anything to do with that?

You saved me man, thanks!

Hi Saul,

Great to see you here…

So, there’s not a ton of examples out there on UAC, but many of us have done 
what you’re describing and later on I’ll try to respond with a config example.

Nick vs Networking has some good, verbose discussions on many modules including;
https://nickvsnetworking.com/kamailio-bytes-sip-uac-module-to-act-as-a-uac-sip-client/

For what you’re talking about doing, I’d probably have the credentials stored 
in a DB (mariadb, Postgres, etc) and then have that register to the carriers.

Asterisk would connect to your Kamailio, and then using whatever logic you want 
(LCR, x-header, favorite, etc) you would then send out to the carrier with 
kamailio handling (via uac) the authentication on the INVITEs.

For incoming, it depends on the carrier how you receive the call. Some carriers 
will send all dids to just your registered username, others will send with DID 
info in the SIP.

Every carrier is a snowflake.

Keeping with the snowflake theme, some carriers are also “finicky” on outbound 
traffic and don’t like to see certain SIP; where some modules like topos may 
assist.

Fred Posner
