asterisk users - Sep 2005 - Is there a clever way to page a group of extensions?

I want to be able to dial a 'pager' extension from an phone on my 
asterisk server, and have it ring all other extensions *except* the 
extension from which I am calling (because call waiting is enabled on 
most extensions by default) - effectively giving me the ability to 
page all other extensions from any phone. The solutions I've come up 
with so far (individual contexts for each extension or customised 
dial strings for each extensions) are pretty gruesome. Is there a 
neat way of achieving this functionality?

Thanks
Patrick

Sure. Fair enough.

1) Define a list of all phones
2) Build a dial string by going through the list of all phones and add
all phones except the one you are calling from (say by account code or
caller ID).
3) Pass built dial string to Dial()

No need for separate contexts or anything like that. Hint: use the Cut command.

If you can't get it work, I can post an example...
