7921 wich firmware versions are these?

[etmarcof]

Hi,

I have seen these firmware versions in some of my 7921 iphones (trough web GUI or ip phone menu):

System Load ID CP7921G-MFG-C.2.LOADS

System Load ID CP7921G-MFG-A.7.LOADS

What firmware version are?

Best Regards,

MC

After uploading/installing 1.3(3), the TFTP server was restarted correct?

If so, can you tell me what the hardware rev is of the phone?

Navigate to the phone web page and see the Hardware Revision section.

https://x.x.x.x/DeviceInformation.

If the hardware revision is 1.x or 2.x, then it should be able to upgrade successfuly.

If the hardware revision is 3.x, then appears related to CSCtc88591.

I think it was TFTP serwer restart problem. We have loaded the image using another CCM in the lab. Thanks for advice.

D.7 is 1.3(4)SR1.

Recent 7921 hw revs can not run 1.3(3) or earlier. Would need ES 1.3.3.0.3 or later.

I have similar issues. Phone web page says "

CP7921G-MFG-D.7.LOADS" Which equals to 1x version.

The CCM server 8 has 1.3.3. Can the phone not be directly

upgraded to 1.3.3. or do we need to jump to a ealier version first ?

We get an error each time the phone boots up. It registers fine

it is just using the manufactured software it seems.

D.7 equates to 1.3(4)SR1.  If pre-loaded with that mfg image then more than likely you have a 7921 hw rev that can not downgrade to 1.3(3).

We do have a 1.3.3.0.3 ES that can be loaded onto the 7921s and has the same scanning and roaming logic.

Otherwise would suggest to upgrade to 1.4(1)SR1, which is available on Cisco.com for download, but the scanning and roaming logic was altered a bit as of the 1.3(4) release.

If you want 1.3.3.0.3, open a TAC case.

If you want to go forward with the latest generally available phone load, would suggest to try on a phone or two first before doing a bulk upgrade.  Can extract the zip contents and upload 1 by 1, restart TFTP service,  set the necessary phones to the desired phone load, then restart the 792x phone to upgrade the image.

This way will not impact other phone firmware.

Yes sorry you are right, I mis-read the D in my filename.

I have upgraded the CCM tftp load to 1.4.1SR1

restarted the phone and it upgraded fine.

The CCM had 1.3.3 and the phone it seems 1.3.(4) as you mention.

And they cannot downgrade. But we decided to upgrade

and it worked for one phone. Now we find a suitable time

to upgrade the 69 others..

Thanks !
