I'm assuming the patterns you given under the partition name are the route patterns/DNs. and you have a CSS as below..
When you place a call to 3330 the potential matches are 3xxx with PartitionA and 3xxx with PartitionB. Since it is a tie in the numbers, the CUCM will select number with the partition listed on top in the CSS, hence PartitionA.
Please mark if helpful.
Deepak is correct. I always think about it like this:
"A CSS is an ordered list of Partitions" Therefore when user dials 3330 it will first look in Partition A and since there is a match under 3XXX it will match with Partition A. CUCM will not look in the later partitions as it hasn't even got down that far since there was a match in the first partition.
Hope this helps!
Hi, it is definitely the Partition A 3XXX, DN 3330 will never be a match for CUCM route pattern 3333, 333X would be an option but not 3333. By the way there are too many confusing interpretations like this around, so help your self with the CCNP Collaboration Exam 300-070 CIPTV1 from Akhil Behl, you can find on the site Ciscopress.com otherwise you'll be confused on the exam day.
