<p class=MsoNormal><span lang=EN-GB>We have had Call Manager 6.1 in place
globally. &nbsp;Clusters are based &nbsp;Europe, US and Asia.&nbsp; 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>&nbsp;</o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>Essentially all internal numbers are
unique.&nbsp; They consist of 7 digits.&nbsp; This comprises 3 digits for an
internal site code and 4 digits for site extension which is the last 4 digits
of the DDI.&nbsp; The design encompasses partitioned addressing scheme.&nbsp;
Internal intersite dialling is accomplished via dialling an access code of 8
followed by the 7 digit extension number.&nbsp; 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.&nbsp;
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>&nbsp;</o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>Our re-seller in the US is stating this is
not best practice.&nbsp; They want to change the dial plan so all DN&#8217;s
are now 8 digits and not 7 beginning with 8.&nbsp; They want to remove the
Translation pattern and give direct access across all DNs.&nbsp; 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>&nbsp;</o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>We in Europe are sceptical of such a
change.&nbsp; We believe this removes a lot of the flexibility of the original
dial plan. &nbsp;Also it cause problems if we want to impose any Class of
Restriction.&nbsp; 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>&nbsp;</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>
