<br>
The problem I'm facing is that dispatcher is always choosing the first destination from the group.
<br>
<br>
I do suspect that dispatcher is not considering registrations as load at all and only counts INVITES as load.
<br>
<br>
If above is correct then is there a way to use dispatcher to count registrations as load ?<u></u><u></u></p>
