<p>Hi all.<br>
</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>I am trying to understand call routing logic of cucm.</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>I created 2 route patterns in cucm 7</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>2!<br>
2XXX (with urgent priority)</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>Now when i dialed 2001, i had to wait 15 seconds. The call wasnt routed as i expected. I opened up Troubleshooting cisco ip telephony book, and according to that, i must calculate the possible results each route pattern defines.</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>1) 2! for 2001 = 1000 combinations<br>
2) 2XXX for 2001 = 1000 combinations.</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>Since they were equal, i can understand why urgent priority didnt work (pls correct me here if what i understood is wrong !!)\</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>Now i deleted the above and created 2 new patterns</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>1) 20!<br>
2) 20XX (urgent priority)</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>Now when i dialed 2001, my call went immediately. Why is this so ?? if i calculate the combinations</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>1) 20! for 2001 = 100 combinations<br>
2) 20XX for 2001 = 100 combinations</p>
<p style="min-height:8pt; height:8pt; padding:0px"> </p>
<p>So why second route pattern was selected immediately ???</p>
