@Jaime Valencia  :

I am facing similar problem.

1. Our CUCM version is 7.1.3

2. Current running old 6921 IP Phones ( firmware version : 9.0.2.0 )

3. Newly shipped 6921 IP Phones registers , but not showing missed call in Call records  ( firmware ver. : 9.3.1.3)

From the Downloads i found that CUCM 7.1.3 Supports maximum up to 9.2(1)  .

How should i Proceed to get the new phones to show missed calls in call records  ?

Jaime Valencia  :

But as i have mentioned , My CUCM version is 7.1.3  and not 7.1(5)+ .

Hence i think  up to FW 9.2(1) is possible.  I found it from the download section description. 9.2(1) is the highest version supported with 7.1.3

http://software.cisco.com/download/release.html?mdfid=282622815&flowid=46236&softwareid=282074289&release=9.4%281%29SR1&relind=AVAILABLE&rellifecycle=&reltype=latest

Kindly Give ur Suggesions.

@ Manish Gogna : Can you please share ur thoughts..regarding this ? what is the upgrade path for this .?
