"LookupBlacklist" not in Asterisk 1.2?


#1

Evidently there was a “LookupBlacklist” feature in earlier versions of Asterisk. It’s even listed here http://asterisk.org/features and others have reported using it. However I am running Asterisk 1.2 beta 1 and the feature is missing or I simply can’t find it.

Will it eventually be in the 1.2 release? Otherwise can I add it via an AGI script?

Any/all help would be MUCH appreciated!

You could have Asterisk make your coffee via the AGI, so yes, it is possible.

As for that specific application itself, not sure. Have a look here in the Applications section (appendix B I believe) and you might find it there:

Muppetmaster -

  1. Thanks for the reply.

  2. I worded my question incorrectly - I know that AGI “can” do it - I was looking for someone who has done it via AGI and perhaps an example script with Asterisk 1.2. I already have the book you pointed me to in hardcover and I have the code from the orginal “LookupBlacklist” function in Asterisk 1.0. (Pasted below)

  3. When I need Asterisk to make coffee I’ll let you know. Just because it’s post #1 don’t assume too much “newbyism”.

This is a simple application to recreate using something like PHP/Perl/C to create a database of blacklisted CLIs and then treat appropraitely. I use Asterisk-Java for an LCR application to retrieve rates from a database and decided which provider to use based on number to dial.

Could even take the code above and convert it into a callable AGI.

You have to add a (j) to the end of LookupBlacklist in order for asterisk 1.2+ to actually make the jump. Like such:

exten => s,1,LookupBlacklist(j)
