<div>I haven't heard of/seen a 4K limit - I've got most customers imposing their own limits between 5000 and 6000 phones per server using 7845's purely as a measure of comfort. I believe that the weighting for an FXS/FXO port is different than that of a PRI, but don't quote me on that. The CallManager Capacity Tool/Sizing Tool should give a good overview of device weighting as well as capacity of a cluster taking into consideration BHCA's, etc. Available on the cisco website - don't have a link readily available.</div>

<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>
