yeah, we’ve tried to improve DNA several times to make it more accurate. something about it being “difficult” ;)

<div dir="ltr">Thanks to all who replied. I hate asking inter-digit questions because they are so basic BUT can be a real pain in the arse if it isn't transparent.<br>
<br>
The issue was an all wildcard RP that ended with<span class="Apple-converted-space"> </span><i>!</i><span class="Apple-converted-space"> </span>in the same PT as all the DNs. DNA didn't match on it because as Wes mentions, there were no numerical matches between
that pattern and the called number that DNA used for analysis.<br>
<br>
Thank you Brian, Wes and everyone else who replied. Ya'll will get a JibJab E-Card at Christmas from me.<br>

Thanks,<br>

yup.
<div><br>
</div>
<div>DNA is a close approximation, but in specific corner cases it deviates from dalib</div>

</div>
<div>I put my chips on an unexpected overlapping pattern</div>
<div><br>
</div>
<div>I troubleshot one of these long ago that turned out to be the intercept pattern for Cisco Messaging Interface (CMI for SMDI integration). When you consider “every dial able number” it is pretty encompassing. </div>

<div>Also, dump the verbose dialing forest and go to town looking around.</div>

<div dir="ltr">Experiencing some strange off-hook delay when dialing.<br>
<br>
Here are the tests I did:<br>
<br>
When dialing an exact match (another DN) from the off-hook position, I get a full T302 delay before the digits are sent. If however, I mark the target DN as urgent priority, it routes immediately (as I would expect).<br>
<br>
I've done some additional testing and placed 2 single DNs in a new PT/CSS and I get the same off-hook delay. If I dial the digits and send EnBloc with the dial softkey, everything works fine.<br>
<br>
When trying to transfer a connected call to a third caller, the secondary transfer button and the target line description do not appear until the delay passes and the phone rings<br>
<br>
I've used DNA and it isn't showing me anything unexpected; save this was a perfectly working system a few days ago.<br>
<br>
I've tried a cluster reboot, and that didn't change the condition. It sounds like signaling delay except for the fact the I can override the issue with Urgent Priority, if it were signaling delay nothing would override it. So I am left with inter-digit timeout
but can't see where it could be coming from, especially with a new PT/CSS that only has 2 DNs in it.<br>
<br>
Thanks,<br>
