1010xxx

I want to use route filter to filter 1010xxx calls. Anybody has done this and can share it?

Thanks

Re: 1010xxx

Sure. The route filter clause you want to match 1010XXX calls is TRANSIT-NETWORK-ESCAPE EXISTS. This matches any call that begins with 101 (in reality, the transit network escape is 101 and the network code is XXXX; the whole "ten-ten" bit is just easy marketing lingo for transit network codes that begin with 0).

Create a 9.@ or whatever pattern with a new route filter with the above clause, and select 'block this pattern' to drop those calls.

Thanks a lot. Any idea what's the difference with transit-network?

Re: 1010xxx

TRANSIT-NETWORK is the XXXX portion of 101XXXX, i.e., it's which carrier you're picking.

You can get an idea of what a lot of those route filter clauses mean by looking at the North American Numbering Plan file in C:\Program Files\Cisco\DialPlan\NANP. It's a text file that describes the numbering plan, and it should be reasonably understandable by anyone familiar with CallManager wildcard rules.
