We're looking at keeping a couple of PRIs at our remote sites, but lowering the number of actual calls that can actually be made over those PRIs. That's because here, we pay for the data portion and the voice portion separately.<br>
<br>
I'm pretty sure there won't be any special configuration necessary to get this working, since the PRIs will come up (or show) with all 23+1 channels available.
<br>
<br>
I'll discuss the options with our provider, e.g. is it cheaper to get a fractional PRI, but I'm worried about the support side of things on the gateway. I've seen references to busying out the channels using the maintenance mode enterprise parameter, but I'm
a little weary of that.<br>
<br>
Thoughts?<br>
