I'm heading a project to install a 75-extension phone system in a hotel. The system will be configured to route all calls over two ADSL connections (For resilience) - for normal operation, in addition to a 4 Channel BRI ISDN connection for emergency sitations where both ADSL circuits have completely failed.
The hotel will have rooms such as 101, 102, etc - And ideally the computers' on reception need to be able to instantly pull up a report of call charges (Preferably customisable by us, to set up margins etc) - Based on room number/extension number.
Integration into the hotels' current PMS is not necessary, however it is preferred that itemised bills showing call numbers and cost (To the hotel guest) can be shown, based on the duration of their stay. (Can be manually input).
Opering base will be the latest version of asterisk/trixbox available at time of writing (trixbox CE 22.214.171.124 (Stable)) and asterisk 1.6
Basic assistance on implementation would be appreciated, and I do have a testing environment in our office where it can be tested before going live.
