[cisco-voip] CCM/CUCM Route Filters

[Lelio Fulgenzi]

I think you've hit on something a number of us are looking at. I've done exactly what you have said. I have created route filters. We have gone one step further and have added router filters for both number dialed without the 1 and with the 1. For example, if you dial 1 + remote local number, I drop the 1 and send it out the remote gateway as a local number. 

Tedious to setup, but not to hard to maintain. I've setup a script that checks localcallingguide.com once a week and emails me updates/differences. Granted, we're in two relatively small exchanges. I think I'll feel a little differently if/when we enable a gateway in the metro Toronto region where there are, as you said, pages and pages of exchanges. 

The good thing is, the more exchanges, the more wildcards you can usually use.

Problem: Customer wants to do TBP least cost routing tail hop-off out of 
the best sites (wherever they can place a local call that has no toll 
nor LD charges). 

Problem: Customer wants to limit some phones to truly local (no toll, no 
LD) calls, and not call anything within the area code (7 digit) that 
isn't local. 

Problem: Some area codes *require* 10 digit dialing if it is local, or 
11 digit dialing if is it LD, but we don't want to just give users 
direct access to DT with the press of a line or a 9, so we have to know 
how to dial each Area Code / Prefix (Office Code in CCM Route Filter speak). 

For all, the solution is to enter in Rate Center info via Route Filters 
and create Route Lists (with digit manipulation) / Route Patterns 
pointing at the right Gateways to use these. 

In smaller Rate Centers, this isn't that much work. In large metro 
areas, these are pages and pages of numbers, requiring dozens of Route 
Filters to create. The interface to add clauses to a Route Filter is 
slow and cumbersome. Worst of all, once you enter in a huge Rate Center 
for a customer, there isn't a way to save that work for another 
cluster/install/customer. 

Or is there? That's my question to all of you - is there a better way 
to create Route Filters or deal with these problems? Is there a way to 
export the Route Filter data so that it could be imported into another 
cluster? If so, then could the Route Filters be created in an automated 
fashion so they could be imported as needed? 

I don't care about copying Route List / Route Patterns / Gateways, as 
this is almost always going to have to be customized, and isn't that 
much work. 

Thanks in advance, 
Jason Roysdon. 

BTW, if you need to look up Rate Center info, try this site: 
http://www.localcallingguide.com 

There are other places sell the info in bulk monthly updates as well, 
such as a product called Area Code World.
