Hello,

the registrations are done each timer interval as soon as init_time + reg_delay > crt_timer. As you have reg_delay spread across 60sec and the timer run each 60sec, very likely all of them are done at once or sometimes in two timer callback executions.

You have to set the timer interval to a lower value, try with 5 or 10 seconds and see the results.

Cheers,

Hi,

We're currently using 60 as well there:

modparam("uac", "reg_timer_interval", 60)

Hi,

I'm using the UAC module in Kamailio to setup about 500 outbound registration towards a single host.

The issue I'm currently experiencing is that when we start Kamailio all this 500 registrations are initiated at once towards the host which can't handle all the requests at the same time.

Therefor I tried to spread the registrations using the reg_random_delay function:

modparam("uac", "reg_random_delay", 60)

I would expect that this would spread the registrations over about a minute but in reality the registrations are spread as follow:

Starttime / Registrations

21:59:14 151

21:59:15 166

21:59:16 127

21:59:18 60

21:59:22 35

So Kamailio is started at 21:59:14 and initiates 151 registrations,

1 second after start another 166

2 seconds after start another 127

4 seconds after start another 60

8 seconds after start the last 35

In reality it looks like some increment is applied instead of calculating a random starting offset for each outbound registration?

Is there any solutions to this issue available?

Best regards,

Ivo Vastert
