<html><body bgcolor="#FFFFFF"><div>Keep failover ratios in mind as well. As an example only, if you have three 7825 servers, with 800 phones registered to each of the two subs, you won't be able to support failover for all 1,600 phones without registering a majority to the pub. Without throwing best practices aside, this probably isn't a realistic scenario, but just wanted to emphasize that failover requirements impact server sizing.<br><br><div>Sent from a mobile device with very tiny touchscreen input keys.

<br>Having spent most of my career at non-partners, generally if you keep at some percentage (say 20%) underneath the recommended maximums for an average use cluster, you shouldn't run into issues (at least I never have). Things get more difficult when you have UCCX or UCCE in the mix, so keep that in mind.<br>

<br><div>The number of phones supported on a given server platform is going to vary based on a numer of elements including gateway/endpoint count, route list count, CTI usage, etc. To get a close feel, you should be using the CallManager Capacity tool or the new UC sizing tool - <a href="http://tools.cisco.com/cucst" target="_blank"><a href="http://tools.cisco.com/cucst">http://tools.cisco.com/cucst</a></a></div>
<div> </div>
<div>In practive, I've seen many customers with 5K+ phones registered to a 7845 class server, they were very light in CTI usage however.</div>

<div>1. What is the practical limit on the number of phones per server. Till now the total number of end-point are 300 (approx)</div>
<div>2. The datasheet states that 1000-phones per server are supported</div>
