[asterisk-biz] Calling Card Hybrid

[Craig Lawrence]

Hi,

Here's a challenge for you:

- A mining company setting up a mine in outback Australia
- 70 rooms for miners accommodation with an IP phone in each
- 25 phones in offices in and around the plant
- need a system that is similar to a calling card system for the miners
- need a standard PBX system for the office workers
- both systems should reside in the same server
- the PBX should allow miners to call other miners in the accommodation
or call to or from office phones to accommodation 
- miners are not permitted to call outside the internal extensions from
their accommodation handsets however if they dial into a calling card
extension they should be asked for their PIN number and then be provided
with a outbound dial tone. They should also be able to check account
balances.
- A billing system is required that will permit the mine management to
charge for each destination as they choose either as an untimed call or
timed. They also need to be able to give the miners a free account
balance of say $50 per month as part of the mine employment terms. The
credit should expire at the end of the month, at which time it will
automatically top-up to say $50. 
- Miners are to have DIDs for incoming calls in the accommodation with a
voicemail system enabled on the phone as a message waiting indicator
light (ie not via email) and they should be able to record a greeting,
re-record the greeting, etc and dial into and listen to messages, replay
and delete messages.
- If an office phone was to dial the outside world and transfer the call
to a room the miner would avoid payment - the customer is aware of this
and accepts this deficiency.
- each miner is to be given a "card" with his User Number on it and
instructions for usage and voicemail on the reverse.  The card will also
tell the miner how to log into the system and change their password
(default password is to be the digits from his or her birth date eg
21/04/75). This instruction card is to be laminated and handed to the
miner when he arrives at the mine.
- the management interface should allow the mine administration to
delete a miner account, add an account, view each miners account
balance, view past calls (and print if needed), add once off call credit
(if the miner wants to purchase more call credit), reset a password and
view from which extension the calls were made.

Would anyone have any suggestion of a product that would do most or all
of the above?

Thanks
