When you upgrade from CCM 4.2.3 to CUCM 8.5, you'll for sure need to
update the firmware in your phones. The updated TFTP server should
address this for you once your phones register for the first time
with the newer CUCM cluster.<br>
<br>
What model of phones do you currently have? <br>
<br>
I don't understand your concern about cost concerning phone
firmware.<br>

Guys, I need to upgrade CCM 4.2.3 to CUCM 8.5, Cisco telle me that
I must, before upgrade CUCM, upgrade Firware Phone with last
firmware files.<br>
<br>
For me is much expensive to do so!!!!<br>
<br>
The question is, Is really necessary to upgrade Firmware phones
before upgrading CUCM 4.2.3 to CUCM 8.5?<br>
<br>
thank you for the answers<br>
<br>
