SIP IP Phone 9971 does'nt get dial tone and can't upgrade to the latest Fimware

[cameroun]

hi,

I have Cisco CME 2901.

The Ios vesion is 15.3(3)M2. 

The CME version is 10.0.

The IP phone 9971 Firmwares are:

dkern9971.100609R2-9-2-2SR1-9.sebn
kern9971.9-2-2SR1-9.sebn
rootfs9971.9-2-2SR1-9.sebn
sboot9971.031610R1-9-2-2SR1-9.sebn
sip9971.9-2-2SR1-9.loads
skern9971.022809R2-9-2-2SR1-9.sebn

But the problem is the internal call between  the IP Phones don't run. for exemple ip phone with dn 100 unable to call the ip phone with the dn 102. when i issue the call, nothing happen.

and more, the IP Phone are registered correctly.

on the phone, theses status messages are displayed:

File Not Found: United_States/g4-tones.xml

File Not Found: Sip_English_States/gd-sip.jar

the commands debugs , nothing happen

Attached are the resultes of the show commands.
