I am in a office where we got 40 cisco 7965 IP phones and an Expansion Module 7916 on each phones,

Did you check the firmware on the phones?

Do they match the working phone?

Can you tell me how can we check the firmware on Phone?

and in the router?

Go to Phone settings --> Model Information --> Load File

OK i will check it now i am out of office, and if the firmware is not the one in the router then i will change the router file which is:

tftp-server flash:IP_Phones/7945_7965/SCCP45.9-2-1S.loads alias
SCCP45.9-2-1S

In CME it is recommended to load a firmware that matches the CME version,

Check this page for CME 10.5:

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme105spc.html

CME 11:

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme11spc.html

and if the firmware is same then what will be the problem

BLF on CME doesn't work that great, I had a lot of problems with it. Sometimes it works, sometimes it doesn't, sometimes BLF starts working after a reboot.

Needed several IOS upgrades to get something more or less working stable

I have check the firmware there are some phones with different firmware and some of them are in the same firmware but with the same firmware, only 4 Phones are working- if i restart all the devices the it will shift to other 4 Phones!

then how to change the firmware for the phones?

I recommend to upgrade your CME to version 11,

after upgrading the CME, use the link below to know how to upgrade the phone firmware:

I have made some changes in "presence" 

In Presence 

"max subscription allowed" i have increase the value 

but now only 15 phones have the BLF

Because 1 Phone using 24 BLF!

because it have the max value of 300 i can't give more then that 

but my boss want it on all 40 phones

can anyone tell me how to increase the value of "Max subscription allowed"

I have attached the Presence file...................

And also tell me if I change the version of CME which is now 9.1 to 11 can the previous configuration will be save or I have to do all the configuration again?

When you upgrade to version 11 only the system OS will change,

your configuration will be reserved and not touched.

and what about the presence!!!!!

Try after upgrading to CME 11.6,

but i think this value is related to the hardware,

you probably can't upgrade the presence more than 300,
