[cisco-voip] Manually updating 7936 firmware? SW version shows blank on phone and web page.

Yes, you can definitely do this. You just have to somehow get the phone to point to the TFTP server, either how you described (ALT TFTP) or by setting up the new TFTP server in a DHCP range only that phone will be plugged into. 

You will need the software images extracted on your TFTP server and the following file: XMLDefault.cnf.xml 

Edit the XMLDefault.cnf.xml file so that the 7936 load is what you want to download. You will have to grab these files from CCO and download them.

Subject: [cisco-voip] Manually updating 7936 firmware? SW version shows blank on phone and web page. 

Hi, 

I was wondering if there was a way to manually update a 7936 firmware 
with a TFTP Server on my PC somehow? 

Issue is I have a 7936 phone and the softkeys don't work for placing 
calls, etc but the keys work in the setup menus, etc so I think the 
keys are ok and it is SCCP version mismatch with CUC 8.5.1. The 7936 
SW Load is blank on the phone and the web page. I can get the phone to 
register to the 8.5 server and call it and the Answer key works, just 
can't place calls from it or do anything else. 

I set up Alternate TFTP Server on the 7936, and the only files I see 
the phone request are XMLDefault.cnf.xml and SEPxxxxxx.cnf.xml for 
it's MAC address. After a few attempts the phone registers fine. I 
tried to put 2-3 different 7936 3.3 versions on TFTP server and change 
the phoneload and the phone never tries to load new firmware. I also 
hard coded the switch port to be directly in the voice vlan and no 
change. 

Any ideas? 

Erick
