The Ultimate Office
Outbound calls

Brief
There were two keysets in the manager's office, two in the administration office, and one keyset in each of the following locations: Pro shop, Canteen, Coffee shop, Score box, Plant room and the First aid room.

A Digimail auto attendant was used to answer all incoming calls.

The manager had unrestricted exchange access, with the manager's assistant and the two keysets in the administration office having partially-restricted exchange access. A major requirement was to totally bar outgoing exchange calls (with the exception of 000) from most extensions.

An equally important major requirement was that the first-aid room was able to call only the administration office or the manager's office (all other extensions could call every other extension). It was this requirement that led to the reasonably complex programming and the expense of providing additional exchange lines just to provide for Emergency 000 calls from every telephone.

Solution
Tenanting the system
The extensions and exchange lines were split into tenants to allow/deny cross-tenant calling. The requirement of allowing the first aid room to only call four extensions plus the essential requirement (because of the possibility of a serious accident in the rink) of every extension being able to have access to an exchange line to be able to call Emergency (000) meant that some exchange lines had to be provided to cater for just these possible emergency 000 calls. A much simpler/saner /cheaper solution could have been provided if the first aid room was able to call every other extension.

The keysets in the manager's office and the administration office and the Digimail ports were placed in tenant group #1. The first aid room was placed  in tenant group #3 and all of the other extensions were placed in tenant group #2.

The tenant calling matrix was set-up as follows to allow cross-tenant calling for most extensions but to prevent the extension in the first aid room from calling only extensions in the manager's office or in the administration's office.

The exchange directory number plus two auxiliary numbers were programmed for tenant 1. Three exchange lines were allocated to tenant 2 and a single exchange line was allocated to tenant 3 so that the first aid room had an exchange line for accessing Emergency 000.

COS settings
The manager had COS 0 (unrestricted access). The assistant manager and the two extensions in the administration office had a COS between 1 and 6 to give them partial outgoing exchange access. All other extensions had a COS of 7, allowing them to call Emergency 000 only.

Exchange line Ringing Position settings
The three exchange lines in tenant #1 ring the Digimail Voicemail UCD. The exchange line connected for tenants 2 and 3 do not have any ringing positions specified as they are for outgoing calls only.

UCD Groups
Three different (one VM and two UCDs) groups were created for

Digimail voicemail (UCD 430)
management (UCD 431)
administration (UCD 432)

Digimail settings
The DigiMail was configured so that digit 1 goes to node 50 (a menu node) which gave users the option of dialling another digit for a specific announcement

As an example, included in the Node 50 announcement, they could:

dial 1 for opening hours (node 51),

dial 2 for special events (node 52)

dial 3 for ticket information (node 53) etc

Digit 2 on the "main menu" was reserved so that callers can direct-dial an extension number if they know the number.

Digits 3 and 4 on the "main menu" can be used to call a specific workgroup (Dial 3 for administration (UCD 432), or dial 4 for the management (UCD 431)).
