<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-GB>We have had Call Manager 6.1 in place
globally. Clusters are based Europe, US and Asia. Our Global
design and dial plan was designed in conjunction with Cisco Advanced Services 2
years ago.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>Essentially all internal numbers are
unique. They consist of 7 digits. This comprises 3 digits for an
internal site code and 4 digits for site extension which is the last 4 digits
of the DDI. The design encompasses partitioned addressing scheme.
Internal intersite dialling is accomplished via dialling an access code of 8
followed by the 7 digit extension number. This works via translation
pattern of translating 8 to 7 digits where the translation pattern has the
access to the partition of the dialled 7 digit extension in another site.
Internal dialing within a site is 4 digits by translation pattern of 4 to 7
digits of the actual real DN.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>Our re-seller in the US is stating this is
not best practice. They want to change the dial plan so all DN’s
are now 8 digits and not 7 beginning with 8. They want to remove the
Translation pattern and give direct access across all DNs. They state
this change will be good for the future.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>We in Europe are sceptical of such a
change. We believe this removes a lot of the flexibility of the original
dial plan. Also it cause problems if we want to impose any Class of
Restriction. We have also not seen anywhere that this would be best
practice.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>If anyone has any thoughts it would be most
appreciated.<o:p></o:p></span></p>
