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?

Highlighted

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:

CME 11:

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

Highlighted

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 recommend to upgrade your CME to version 11,

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

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?

Highlighted

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

your configuration will be reserved and not touched.

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,
