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

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,
--Sergiu
