luisprata: I already have CHANNEL(category=9) ready for the next release, that would allow to set and get the calling party category from the dial plan, thus, you could take decisions based on the calling party category. Is that enough for you? or are you thinking in something else? you can contact me at my google mail “moises.silva”. I am in Mexico, by the way.

Where are you from ?

Well, I would like to discuss a good option to implement Collect Call Blocking.
In Brazil, calling_party_category == 9 indicates Collect Calls.
I would like to write an application, example, to check this,or
implement a new parameter to CALLERID(category) to check. And if it’s 9, then block or accept.

I was thinking about documentation of unicall stack, what do you think ?

Thanks.

Please, where can i get the installations steps?

Thanks a lot.
