There are a number of situations in which we do just this, but in doing
so, and depending on the customers location, can price us out of the
market. Such as a customer looking for >23 channels.

We don't currently connect to any carrier via VoIP, all of the equipment
to transcode G.711/G.729 -> T1 Trunking is already in place.
Even in the event where we do connect to a carrier via VoIP, we'll
transcode to G.711 (or other) before passing the call off.
