Smart IPT Guys…

I am working on designing CUCM 7.0 for customer and wanted to start a conversation on how to build Partitions / Route Patterns using Local Route Groups. For starters let's assume all locations are in the domestic US. Let's also assume we are building COS using Cisco's Line / Device.

At first glance it seems pretty straight forward, put all the “PSTN” route patterns into a single “PSTN” partition that is used by every location and point these Route Patterns to a Route List that is configured to use “Use Local Route Group”.

But what happens with locations that use / require a combination of 7 and 10 digit dialing (like the Minneapolis / St. Paul metro area). It seems that the benefits of using a local route group are somewhat diminished in this scenario.

One solution I can think of is going with a “Hybrid” approach. So for all locations put the following in the “US-PSTN” Partition with the RL configured to use “Use Local Route Group”

911

9.911

9.1[2-9]xx[2-9]xxxxxx

9.011!

9.011!#

9.0

9.[2-8]xx

And then for a location in say Minneapolis MN put the following in the traditional “<SiteCode>-PSTN” partition.

9.612[2-9]xxxxxx

9.763[2-9]xxxxxx

9.651[2-9]xxxxxx

9.952[2-9]xxxxxx

9.[2-9]xxxxxx

Then for a location that only allows 10-digit dialing for local calls put the following in the traditional “<SiteCode>-PSTN” partition.

9.[2-9]xx[2-9]xxxxxx

Sure we could simplify the administration and force all users to dial 10 digits. We then build 9.[2-9]xx[2-9]xxxxxx in the same US-PSTN partition. But that would the user experience at some locations.

I appreciate any thoughts or suggestions.
