Employees are the victims in deals like this.  I extend my sympathies 
and hope you find good employment should you find yourself the victim 
of "synergy".

Uh, no.  Incumbent has a real meaning.  Conflating ILECs and CLECs is 
like saying that the major political parties are fundamentally 
identical.  ILECs are the inheritors of a valuable outside plant 
built as a statutory monopoly with guaranteed profits -- no more a 
"business" than operating an interstate highway.  CLECs invested risk 
capital to break that monopoly and provide customers with superior 
service at better prices.  Some are big, some little, and some are 
better than others, but the divide between CLEC and ILEC is as wide 
as the Pacific Ocean and as deep as the Marianas Trench.

Whoa.  I'm talking about connections to the PSTN, not tie lines 
between your own sites.  You can of course use PRI as a tie line, but 
that's most often done via MPLS.  The PSTN, however, is currently 
delivered in TDM by incumbents everywhere, and in SIP by CLECs in 
some places.  That's all I was saying -- if you're in New York City 
or even a Tier 3 market key city, you can probably get SIP from a 
CLEC.  But there are rate centers that vitelity isn't going to 
deliver, and they resell a bunch of CLECs.  And they can cost more 
than a local CLEC or even in some cases ILEC, especially when you 
have to backhaul them.

You can use any protocol on an EEL -- IP is merely a multiplexing 
header, not a protocol, so if you want to use VoIP to deliver the 
local service on an EEL, you can.  Or  TDM, or ATM, or MPLS, or 
Carrier Ethernet, or whatever else you prefer.

True.  PRI cards cost more.  Lower volume, etc.
