<div>new to voip. reading and reading.</div>
<div>situation.</div>
<div>central ccm cluster.</div>
<div> </div>
<div>i have over 200 sites.</div>
<div>5 sites - voip</div>
<div>rest centrex + key system</div>
<div> </div>
<div>the debate is what to do with dial plan.</div>
<div> </div>
<div>users at each site are used and fond of using 4 digit dn internally.</div>
<div>but looking ahead 4 digit dn will not suffice.</div>
<div> </div>
<div>can you experts out there, suggest how to give 4 digit dn internally and 10 digit outside of the site, inter-site.????<br> </div>
<div>or any thought?</div>
<div> </div>
<div>i appreciate any comment.</div>
