Hi All!

I have a problem connecting to our phones via Web.

When I look at the device list on CUCM there's a hyperlink attacherd to each phone.

When I click the URL I get an overview of the phone.

If I try to click on the network settings I get an HTTP error 400.

What's the problem?

The phone's Web Acceess setting is Enabled.

Tnx in advance!

This behavior is expected when the GET request itself cannot be parsed because of some kind of packet corruption. If you send a bad request to the IIS Web server, the Custom Errors functionality is not invoked, which causes the “HTTP Error 400" error message. To more completely determine what may be occurring, obtain a network capture of the communication packets between the client receiving the error and the Web server itself.

I'm having the exact same problem with our 7911s and 7941s. Occurs on all of the phones in the company.

I can access the Device Information page by clicking on the link from the CM Admin page, but if I type the phone's IP into a web browser I get the HTTP 400 error. I get the same error if I click on any of the links in the Device Information page.

Looks to me like a bug in the phone's firmware??

Firmware I am using is:

7911: SCCP11.8-3-3SR2S

7941: SCCP41.8-3-4SR1S
