<p class=MsoNormal><span style='color:#1F497D'>Wow, direct messages through
this forum &#8211; not sure if I should be honored or scared! </span><span

<p class=MsoNormal><span style='color:#1F497D'>CUBAC &amp; CUDAC use CTI to
show line state &#8211; its all done via CTI. However, CUEAC uses CTI along
with AXL as you say. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>The reason for this is that CTI
does not scale &#8220;cluster wide&#8221; &#8211; it has limitations. Therefore,
by using the SuperProvider model (which uses AXL), the line state is handled on
a &#8220;per request&#8221; basis &#8211; therefore, as long as the operator
does not need to know the status of 5000 phones <u>at the exact same time</u>
(which they wont of course), this provides the scalability to show line state
on any phone in the cluster &#8211; even if the cluster has 50,000 phones<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Regarding the website, this is
just because we posted some videos that were specific to CUEAC, so we created
the page there. You&#8217;re right about the CUBAC/CUDAC &#8211; it is
misleading as its not there &#8211; I&#8217;ll have a look at this and see what
we can post up there to make it more wide reaching<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Let me know if you need any more
clarification on this &#8211; as I say, the main reason for the CUEAC
difference is technical &#8211; to work around CTI Scalability/Load issues on
the CUCM<o:p></o:p></span></p>

<p class=MsoNormal>Bennie why does CUDAC and CUBAC use CTI while CUEAC uses
AXL? Is there a plan to make them all use AXL at some point? Also why does the
ARC website only show CUEAC as a Cisco OEM product and not the others? <o:p></o:p></p>
