Why would you go through the trouble of encapsulating that in some sort of presence layer? Just query Redis directly with redis_cmd() from the ndb_redis module.
Whether you need an SQL database or can get by with Redis is a complex topic. It's ultimately a question of how complicated a feature set you need and the structure of your data and workflow as a whole.
When viewed in isolation, as a single objective, routing with Redis appears to be much more performant. But most call routing platforms consist of a lot more database interactions than just a single route lookup. That's where the added value of a full-on RDBM becomes relevant.
