a bit... One work around for this is to create a ram drive of sufficient size

It's going to be the disk io from sqlite. The presense states are all
stored in sqlite (or odbc) data source.<br>

Is the presence mechanism waiting for some response from the network?<br>
I’m assuming it’s waiting on something external because I
couldn’t find any CPU activity…<br>

9996 is not a good test extension because it does not generate any audio unless
it gets some.<br>
9998 that generates a tone or make up an ext that plays a file is a better one.<br>
<br>
Processing of the sip calls can be delayed by the presence stuff which is very
intensive, you can try turning it off and see if you get more calls. Also
you should compare it to what happens with the test exten first in the dial
plan.<br>
