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>

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 max
of 7500 phones
on a 7845, however in side discussions Ive heard mention that this
should be
limited to no more than 4000 phones on a server in large deployments.
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>
