[SR-Users] UAC reg_random_delay issue

[Daniel-Constantin Mierla]

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,
Daniel
