[cisco-voip] Phone limits per server

[Lelio Fulgenzi]

The only thing I've heard is that you have to change a service parameter to up the 7845 from 5000 to 7500 devices and that it's an extra licensing cost. 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. 

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). 

With each revision of hardware, I suspect they would handle 7500 devices without blinking.

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? 

Also, since each gateway endpoint is a “device” is there a major weighting difference between FXO/FXS endpoints and PRI endpoints for capacity planning?
