-----------------------------------------

Thanks Jaco! pbx_dundi is extended support. If you need it in soon, you'll want to round up some interest on the asterisk-dev list or IRC. There are a few other DUNDi patches that need looking at as well. You can find them by filtering with the PBX/pbx_dundi component.  Bonus points for you if you find someone willing to review and test them all then push them through to commit!

> Should dundi_lookup_internal return a negative number then so will dundi_lookup, which usually gets assigned to num_results, which is an unsigned int.  Later when sorting this number is taken "as is", which then results in an out-of-bounds situation and a segfault (usually).
