7975 shows auth fail when it uses SIP and to upgrade its firmware?

I use phone 7975G to register to CUCME by sip.

7975 shows auth fail when it upgrade its firmware?

I changed different firmware version. It still show 'auth fail'. I guess that it's not a firmware version problem.

But what's wrong with my 7975.

please copy paste here config

please copy paste here config for SIP phone

as I know there should be username cisco and password cisco

 

and dont forget to rate post

 

 

voice service voip
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip

 

#### SIP Phones create Voip Dial-peers. so for SIP to SIP, SIP to H323   you need to allow the connections. SCCP phones create EFXS POTS   dial-peer. By Default IP-IP call is blocked)(Random Fact).
fax protocol pass-through g711ulaw
modem passthrough nse codec g711ulaw
sip
bind control source-interface FastEthernet0/0.426
bind media source-interface FastEthernet0/0.426

 

### Bind Control and media to the interface with the same IP Address on   source-address x.x.x.x . Else you will run into problems when you try  to  register Phones over a Layer 3 Link.
registrar server

 

### Needed for phone to register

voice register global
mode cme
### Change mode to CME
source-address 14.160.126.77 port 5060
### Should be the same as bind control and media when you have InterVLAN Routing

max-pool 10
authenticate register
### Needed for the phone to authenticate with username password, in intervlan registeration setup
tftp-path flash:
### All the config files for the phones will be stored here.
create profile sync 0174426467043125
### Make sure you enter this command everytime you make some changes.!!!!!! Very IMP!

voice register dn  1
number 1234
### DN for the Phone
voice register pool  1
id mac 0023.5E17.D275
### Mac Address of the Phone trying to register. Which won’t be used an   authentication method when registering in Intervlan register scenario
type 7942
### Make sure you have this in here.! Else SEP<MAC-ADDRESS>.config wouldn’t be created.
number 1 dn 1
### Assigning 1234 to line 1 on the phone
username cisco password cisco
### Credentials the phone uses when it tries to register in case of intervlan.

It can not upgrade firmware. I have two kinds of ip phones: 9971 and 7975. 9971 works well, but 7975 shows 'Auth fail'.
