But more detail is available on the Ofcom website at http://stakeholders.ofcom.org.uk/telecoms/numbering/ The configuration below is the dial-plan configured on a Cisco UC500 device, an IOS based small business product that makes use of Communications Manager Express for phone control, by the CCA (Cisco Configuration Assistant). The example dial-plan contains a lot of specific matches which allows for more precise class of restriction (COR) configuration for specific types of calls and minimises post dial delay. dial-peer voice 52 pots description ***Free Numbers - 11 digit** destination-pattern 9080[08]... dial-peer voice 53 pots description ***Free Numbers - 10 digit** destination-pattern 90500... dial-peer voice 54 pots description ***Free Numbers - <= 10 digits** destination-pattern 90800...T dial-peer voice 55 pots description ***International Toll Free** destination-pattern 900800T dial-peer voice 56 pots description ***Voicetext Services** destination-pattern 91800.
