Outbound routes in 2.5.x?

I just upgraded to the new 2.5.x version and all went well. (I am running a PBX-in-a-Flash box). One feature I’ve anxiously been waiting for is outbound routes per extension. I might have missed it, but is this in the new version? I need to be able to set a group of phones to dial out on one line, and another group of phones to dial out on a different line. I have seen many posts asking for this and am soo bummed if after all this waiting it still is not there.

I do that with custom contexts.
I just upgraded to 2.5 on astersisk 1.4 and the custom contexts module still works.
