Entrance phone/Blocking calls within a building.

[dafvid]

Hi.

I trying to find a solution where I can block an entry phone to a building so it can only call those extensions within the house.

The only solution I can think of is to create common abbrevations for all the extensions inside the building and use an own class for those, and then block the entry phone so it can only call those abb. numbers within that specific class. However, this doesn't seem like a neat solution for me and wonder if any of you have other ideas how to solve this.

Part of the problem is I want those inside the building be able to open the door to the building by pressing '5' on their phones while talking to those at the entrancephone. So it's not good if the entrance phone can call anyone outside the building

1. make nadap;
2. look in nadap for an unused cdcat (example: 12)
3. think about, which leading digits should your entrancephone be allowed to dial (for example 1 till 4, because your normal extensions are 100 till 499. Be sure, that no destinations are within this numberplan!)
3. Allow the cdcat=14 to dial all ext. with 1xx to 4xx (nacds:num=1&2&3&4,cdcat=12)
4. make exccp:cat=all;
5. look in the printout for an unused category
6. make adcdp:abb=all;
7. look in the printout for un unused class between 0&&3 (Example: all abb are programmed with class=0, so class=03 is free for our purpose. If all abb unfortunately are programmed with class=0&&3, then you have a problem, then delete all abb and set again with the correct class, normally "0", but it must be the same like your extensions: the two leading Bits in traf!)
8. make ksddp:dir=all;
9. look in printout for the two last bits in traf, normally it should be the same for all normal extensions (Example: 01 is used)
10. make a new category with exccs. The most important thing is here the traf. In our example it must be: traf=03121201
11. Now programm the new number with the new cat or change the ext, to the new category, if extension already exist.

result: Your telephone is only allowed to dial extensions in your house. But it can not make external calls or use abbrevating numbers. The phone can not press the "5" to open the door... For pressing "5" your colleghes will use the "Inquiry-Button" (if cat is correct).
