Hello,
just pushed a patch to allow enabling/disabling registration feature for
all records at ones:
-
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.

Thanks for your suggestions. For now I'll
give a try your
approach #1.
Couple extra doubts:
1- do you think an expiry of say 60s is too low? or is it
reasonable? (I
know it will depend a lot on the number of
records in database,
but in this
case it's very little, like ~50 or so).
2- can I set uac module to initialize without sending any
REGISTER requests
("start with all records in database
disabled")? If answer is
no, then my
idea would be to set uacreg colum reg_delay to
say 10s or so to
give time
to kamailio to startup, and than have an external
script
manually disable
them before the delay expires. What do you
think?

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?
Best regards,
Henning
