Im currently installing a 6.1 cluster and reworking our route patterns, at the moment we have individual router patterns for each location.
I've read that best practice states if you want to filter numbers then don't use the cisco numbering plans as the filters could become complicated but using 9@ simplifies the route patterns.
If I don't use this then I will have to create individual route patterns but what I want to avoid is the situation we have now and thats 153 route patterns just for dialing international numbers from London.
Does anyone have any comments and suggestions on creating the minimal amount of route patterns following the countries dial plans???
Thanks in Advanced
