<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Arial","sans-serif"; color: rgb(31, 73, 125);">I have been thinking 10 digit dialing also, due to the fact that
we are going to be hosting users across like 30 different area codes.
Allowing each location to dial users in the same location with 5 or even 4
digits is easy, but I just don’t think 5 digit dialing between locations with
that many different locations is worth the hassle and headache. I have
also seen where you have to plan for the inevitable changes that will occur,
such as new sites stood up, and a host of other things, like we had one site
that actually changed numbers when it was converted from one provider to
another (there was a good reason for it). I like to take the approach “expect
the unexpected”, otherwise you set yourself up for a mess later.
Thanks for all the input and info and especially the dial plan link. It
is really going to help a lot.</span></p>

<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Totally agree. We had our Cisco CCIE VoIP
verify our dial plan before we deployed it. I do agree with Walt that 7-digit
dialing is a good thing. It is scalable. Do use translation pattern for your
5-digit dialing. <br>
