That's true.  I was assuming we were talking about telephony here 

There are a few uses ISPs have for CLEC licenses that have nothing to do 
with phone.  One is rights-of-way for network build-out, pole 
attachment, etc.  Another is getting UNE rates on leased circuits 
instead of wholesale access rates.  That still required interconnection 
and/or CO colocation for aggregation, but not SS7.

Yep.  All these devices pretty much work on the same principle, although 
even the Linux-based ones have proprietary failover technologies and 
don't use Linux-HA.
