We have transitioned away from the 'device units' approach that used to
be in the SRND. When we were using that model the multiples were
something like:<br>
phone with 1 line at X BHCA = 1 unit<br>
monitoring that phone via CTI = 4 units<br>
registering a CTI device such as CTI route point = 8 units<br>
<br>
Note, these are approximations. The information is still available in
older SRNDs. Unfortunately that model did not scale very well thus the
move to the new capacity calculators. The big challenge now is that CM
does not generate simple concise values to plug into the calculators.<br>

you say massive performance hit, what do you mean? Just a rough guess. <br>

Case in point, we have Unity Express boxes, IPCCx boxes. Does each CTI
port shave the load capacity down by 100 phones or something?<br>
<br>
We also have a Cistera appliance that uses CTI super provider to
monitor all 8000 phones or so.<br>

SRND is 'guidance'. The most respected source today are the capacity
calcaulators which are currently only accessible to partners:<br>

Maximum load is determined by devices, number of lines, and features
being invoked. Anything using CTI is still a massive performance hit.<br>
<br>
Net: it is not as simple as server X supports Y devices.<br>

<p class="MsoNormal">According to the SRND for 6.1 you can have a

Is
that the case and is there documentation to back it up?</p>
<p class="MsoNormal">Also, since each gateway endpoint is a
“device”
is there a major weighting difference between FXO/FXS endpoints and PRI
endpoints for capacity planning?</p>
