Unzip the file (spa525g-7-5-4.bin and spa525g-7-5-4-bt.bin) into the folder that your TFTP Server points to.
Make a folder for the 525G2
cd flash:/phones mkdir flash:/phones/525G2 copy tftp flash:/phones/525G2
Enable the files to be delivered:
tftp-server flash:/phones/525G2/spa525g-7-5-4.bin alias spa525g-7-5-4.bin
tftp-server flash:/phones/525G2/spa525g-7-5-4-bt.bin alias spa525g-7-5-4-bt.bin
Tell the UC that this is the phone load you want delivered to the phones:
telephony service load 525G2 spa525g-7-5-4-bt
(spa525g-7-5-4-bt includes Bluetooth and spa525g-7-5-4 doesn't, you can only pick one. I like to have both available)
Make sure that the ephone type is 525G2 on all the ephones that are 525G2. Mine were all setup as 525G too). Update all the ephones to change the types to 525G2. You can do a script to restart them as you update too...
ephone 7 type 525G2 reset ! ephone 8 type 525G2 reset ! ephone 9 type 525G2 reset
Figuring out the CDP issue now . I'm having to tell each phone that it need to use the voice vlan. My fault to editing the CCA deliver to match existing vlans. I would have hoped that this would be an editable feature by now... Even worse that this phone and system have both been out for a long time and to not have any firmware for 525G2 available in the CCA is not nice!
