<p>Hello,</p>
<p>if you have:<br>
</p>
<p>modparam("uac", "reg_random_delay", 20)</p>
<p>modparam("uac", "reg_timer_interval", 20)</p>
<p>Then all are sent because the next timer callback is executed

<p>modparam("uac", "reg_timer_interval", 10)</p>

<p>Hello,</p>
<p>registrations are sent on a timer callback function
executed every N secods that is specified via a modparam
(check the readme). If the next timer callback is going to
be executed after the delay value (or when the
registration expires), then the (new) registrations are
sent on the current callback execution. Could be this
situation.</p>
