<div>There is a service parameter that will keep you from allowing more than 5000 phones to register to a single server. It can be changed, but should only be done so if you're running a server capable of supporting more than 5K phones (and have run the scenarios through the capacity tool, etc, caveat emptor)</div>
<div> </div>
<div>Code Red/Code Yellow are different scenarios under which CallManager will either start throttling call attempts (code yellow) or outright rejecting call attempts (code red) in an attempt to recover from some particular problem. I've seen it occur primarily over high CPU usage, but I'm sure Ryan and/or Wes can/will chime in with more specifics :)</div>

When you purchase CUCM for 7845 it comes with only 5000 "licenses". To be legit, you need to purchase the RTU license to go up to 7500.<br>
<br>I've heard nothing about not using a 7845 for 4000 devices. We currently run over 3500 devices on each of our 4 7845s (5 year old hardware too) and have not had any issues (so far, touch wood).<br><br>With each revision of hardware, I suspect they would handle 7500 devices without blinking.<br>

<br><br></span></p>
<p class="MsoNormal"><span style="COLOR: black">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?</span></p>
<p class="MsoNormal"><span style="COLOR: black">Also, since each gateway endpoint is a “device” is there a major weighting difference between FXO/FXS endpoints and PRI endpoints for capacity planning?</span></p>
