SPA525G2 Phone loads


I have added 2 SPA525G2's to a UC520 and the phes are not getting their configurations.  The phones are getting their IP addresses but the dispaly does not show user or the lines. I am using CCA 2.2(4) I use the 525G phone load for the phones.

Hi Jibu,

I have seen this.  Can you check to see the CCA drop down box in voice extensions GUI has model set to SPA525G2 and not just G?

This may be new, so you may need CCA 2.2.5.

I updated the CCA to 2.2(5) and see the option SPA525G2 listed but then when i click on the dropdown it lists 525G only.  I cannot proceed with the SPA525G2 option

Delete it and readd it.  You cant change the model on the fly from CCA.


Hi Jibu,

1. Can you check the CLI to make sure your CCA config has made it to the router?


ephone  1
device-security-mode none
max-calls-per-button 2
username "xxx" password xxx
type 525G2
button  1:10

you could type in 'show run | incl '

2. I know your phone has an IP address, but it is in the right vlan and do you have the option 150 ip there ?

3. Has your router the right time? if not correct this and re-create the CNF files under telephny service

4. the SPA525G2 has a load 525G2 option if you want to update the firmware

You may need to select the reset option from the menu, but it should work on a power cycle.


Here is the CLI output

ephone  1
device-security-mode none
mac-address 68EF.BDCC.AA2E
ephone-template 16
max-calls-per-button 2
username "TLremoteA" password 1234
type 525G
button  1:10 2m15

mac-address 68EF.BDCC.AA2E

Even after power cycle, the phone remains the same.

Can you change that to G2

It does not have the option on the drop downs and therefore cannot type it in,

Can you try clicking ADD New User in the CCA menu and change the MAC to 0000 0000 0001 and look

at the pulldown for it?   Its there :-)

This is why I am sugesing delete the existing 525G and readd it as 525G2

Deleted the phone and added it and dont see the option.  I even went to the toplogy view and used option "Add to Voice Network"fig and it opens the Voice Config and it lists the Phone with SPA525G2.  I add the user and when I apply the change, it errors out with the Phone Type and cannot proceed further without choosing a phone type.

What IOS/CME you running?

I think you need to see support for it there first.

It is running 7.0.3.

not supported in that load.
