Hello,
just pushed a patch to allow enabling/disabling registration feature for all records at ones:
- https://github.com/kamailio/kamailio/commit/49f354276df3cfc2cdb0f85b5a1839f86733aead
I haven't tested it yet, maybe you get a chance to give it a try and report the results.
Cheers,
Daniel

Hi Henning,
Yes, it would be for the HA setup.
So for example, say we have (I'm making it up):
modparam("uac", "reg_start_disabled", 1) ## This tells uac module to start with all records in `uacreg` table disabled.
1- Start kamailio on both nodes (no registrations are sent by any node).
2- Start keepalived on both nodes, some tests are done, the VIP is enabled on one of the nodes (MASTER). Keepalived would then run a script that would effectively enable all registrations (looping through all the records in the uacreg table doing a `kamctl rpc uac.reg_enable ...` or a future possible `kamctl rpc uac.reg_enable_all` :P).
That way, only the active node would be proactively sending the outbound registrations.
I don't see any of this a problem, as right now both are sending registrations using the same "Contact:", so any incoming requests will be directed to the active kamailio. This is just to keep things tidy and not have 2 servers sending outbound registrations when it isn't strictly necessary.
What do you think?Thanks,Joel.

Hello Joel,
60s is indeed low. I saw some reports of people use something like this in NAT
settings, but I'd suggest for something between 2-3 minutes. This gives you a
bit more room for eventual errors during a restart or something like this.
About the second question - I just did a quick check in the code. It seems
that the uac module is reading during child_init the DB records, and there is
currently no setting to disable this.
But I did not fully understand the rationale behind this question, is this for
your high-availability setup or something like this?
