Hello Sergiu,
Interesting. I suspected something like this in the past as well but never looked into the
randomness features in uac.
Let’s wait a bit if somebody else might comment on it, otherwise please open an issue
about it on our tracker.
Cheers,
Henning

Subject: Re: [SR-Users] UAC reg_random_delay
Hi Henning,
That's my understanding as well, but in reality seems like it all happens
simultaneously, without some kind of delay.
Here's what I have:
· modparam("uac", "reg_random_delay", 20)
· 10 uac records
· expires=300
· reg_delay=0
kamcmd uac.reg_dump | egrep delay
reg_delay: 13
reg_delay: 7
reg_delay: 3
reg_delay: 2
reg_delay: 8
reg_delay: 1
reg_delay: 2
reg_delay: 14
reg_delay: 17
reg_delay: 18
Following restart of Kamailio:
· 1st x10 REGISTERs are all sent out the same millisecond.
· Contacts saved, received 200 OK with Expires: 300
· after 280 seconds, another x10 REGISTERs are all sent out the same millisecond
· and so on
Thanks.

Hello,
this are two different concepts:
· reg_random_delay is a global parameter to randomize the registration delay for the
records
· reg_delay is a parameter for the individual contacts
So it seems to randomize the reg_delay value due to the set reg_random_delay for records
with reg_delay = 0.
Could you maybe also observe a second registration after the initial registration, if it
stills send out all requests the same time?
Cheers,
Henning

Subject: [SR-Users] UAC reg_random_delay
Hi there,
May I know what exactly is supposed to be "delayed" in the UAC registration?
modparam("uac", "reg_random_delay", 20)
I have records stored in DB with reg_delay=0. When doing uac.reg_dump, I do see the value
of reg_delay being random for various records.
However, after restarting Kamailio, the registrations are all sent out simultaneously,
there doesn't seem to be a "delay", whatever the purpose is supposed to
be.
Can someone clarify please?
Kamailio 5.5.0
Thanks. Regards,
