Max,

Not to worry, we will try to help.

Please ensure that you have the DHCP/TFTP servers reachable to phone & also dont try to get directly on 9.x firmware versions, try some lower version first & upgrade to 9.x at later stage.

What is the CUCM version & what firmware you have in it for 7942 ?

In case, you could see some firmware version being loaded in your 7942, please post that version here so that we can look from that perspective too.

Access your CUCM IP using a browser ( an IE or Mozilla firefox ), login using the credentials & the main page will show the CUCM version.

Mostly if you are using HTTPS, you must have cancelled the request on certificate page.

If you got the option " Continue to this website (not recommended)." click on it to proceed further.

Remember I meant accessing CUCM Server IP using browser not the phone.

If not CUCM, what is it ? CME ? or any other PBX ( as the phone is a SIP Phone ) ?

I had a similar problem last week doing a factory reset on a 7942 phone running SCCP42.9-1-1SR1S on a Call Manager Express 8.6 setup. Within CME the phone would just keep looking for term42.default and sit their loooping.

To overcome the issue I connected the phone to a CUCM 6.1 install and it successfully uplaoded the default boot loader and flashed to an 8.0 SCCP image - then I connected the phone back to CME and it upgraded back to 9.1

Hope this helps - maybe it is your tftp bindings within CUCM? Do you have access to another CUCM system that you can try to firmware it from?

Re: hard reset killed cisco 7942

1.  download the zip file that contains the 8.5(2) SCCP files for the 7942 and place those on the root of the tftp server (i use a laptop with a tftp server running)

2.  set up a dhcp scope with the option 150 to point to the tftp server (i use a 3750 switch).

3.  boot the phone up and wait for it to upgrade to 8.5(2).

4.  when it tries to register after completing the upgrade and rebooting, unplug the phone and plug it back in to your network accessible to call manager and the phone will then upgrade to the 9.x version on call manager or repeat the process with the 9.x files if you don't use call manager.
