Both are actively maintained.

However, depends on what you map to a DID/prefix, there might be other 
solutions using simpler structures that can be relevant in performances 
for your case.

For example, if you map a DID to a destination ID or address, look at 
mtree module:
http://sip-router.org/docbook/sip-router/branch/master/modules/mtree/mtree.html

It is for devel version (upcoming 3.1) but you can just copy it for 3.0 
(I use it there and iirc works out of the box) - you can have many 
tables loaded in memory, each with lot of records.

If you map to destination ID, then dispatcher can be used to map the ID 
to an address.

Cheers,
Daniel
