Urgent priority

[iptuser55]

If you ticked urgent priority on a translation or route pattern such as 1212555xxxx but you also have a directory number with an exact match 12125551234- would the DN match or would it wait until the last x then timer 302 and then select the urgent priority?

thanks

It deson't wait for the T302 timer when you have Urgent Priority checked.

DN is always urgent priority unless this is CUCM 10.X where you can uncheck it.

Chris,

You have that backwards.  Probably a typo.  DN's have always been non-urgent priority, unless you are on CUCM 10.0 where you can make then urgent priority. (Source)

This is why a globalize +E164 numbering plan requires translation patterns matching your DN ranges to avoid T302. (Source)

Anthony,

Do you have any documentation or examples of urgent DN reasoning and setup in UCM 10?  I'm still trying to grasp E.164.

Checking the urgent priority checkbox does not force a match, it stops digit collection.  Kind of weird, I agree.  So, in your example, the DN would match because of the matching rule in CUCM of most specific match.

hi- That is my thoughts. I was under the impression that the urgent priority worked as follows

9.11- urgent priority

Route Pattern 9.112 

Result the 9.11 would match rather then 9.112 due to the urgent priority. 

My first thoughts was that the DN would always match first due to either specfic match also the urgent priority only works for Translation and pattern patterns not Directory Number. 

Anthony- Are you saying that the DN would match rather then the route pattern due to the more specfic match?

thanks

It is pretty well documented in the SRND with a few good examples.

Urgent Priority

•The Urgent Priority checkbox is often used to force immediate routing of certain calls as soon as a match is detected, without waiting for the T302 timer to expire. For example, in North America, if the patterns 9.911 and 9.[2-9]XXXXXX are configured and a user dials 9911, Unified CM has to wait for the T302 timer before routing the call because further digits may cause the 9.[2-9]XXXXXX to match. If Urgent Priority is enabled for the 9.911 route pattern, Unified CM makes its routing decision as soon as the user has finished dialing 9911, without waiting for the T302 timer.

•It is important to note that the Urgent Priority checkbox forces the T302 timer to expire as soon as the configured pattern is the best match for the dialed number. This does not mean that the urgent pattern has a higher priority than other patterns; the closest-match logic described in the section on Call Routing in Unified CM, still applies.

For example, assume the route pattern 1XX is configured as urgent and the pattern 12! is configured as a regular route pattern. If a user dials 123, Unified CM will not make its routing decision as soon as it receives the third digit because even though 1XX is an urgent pattern, it is not the best match (10 total patterns matched by 12! versus 100 patterns matched by 1XX). Unified CM will have to wait for inter-digit timeout before routing the call because the pattern 12! allows for more digits to be input by the user.

Consider another example, where pattern 12[2-5] is marked as urgent and 12! is configured as a regular pattern. If the user dials 123, the pattern 12[2-5] is the best match (4 total patterns matched by 12[2-5] versus 10 patterns matched by 12!). Because the T302 timer is aborted and because the urgent-priority pattern is the best match, no further user input is expected. Unified CM routes the call using pattern 12[2-5].
