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>
