Config and reflash of Cisco 7940G

[j666gak]

Hi, i'm hoping somebody can please help me.

I have been using VOIP via a softphone for a couple of years now, I decided that I wanted to have a go at setting up a Cisco phone. So I have got a 7940G second hand which works fine. I am a home user trying to learn so I am using a BT Homehub with dynamic IP and SIP on voip-talk.org

The phone was still configured form the previous owner with subnet, DNS, FTP, VLAN etc. I couldn't find a how to edit these settings, so I thought if I set it back to factory defaults, told it to delete network cfg. I thought on restarting it might ask me to input the detail? but it showing "configuring VLAN" and then constantly stays on "configuring IP"

although it stills picks up an IP via DHCP and I can ping it ok, I can also browse on to the web interface which show the following info

and in the the device debug log it keeps showing this error: 2027-08-06 09:04:39.990 Code:8107, P:0, S:0

the date doesn't change but the time does, not sure if the is any help?



Basically I need to know first all how to at least change the settings, as I don't have access via the phone itself or the web interface. And I will probibly also need to reflash the firmware with something that will do SIP.


Thanks for looking and your help

Cisco VoIP phones are really designed to be connected to a Cisco CallManager using SCCP, which manages the phones remotely. You mention web interface, are their any options to click like setup etc? Also if you dig really deep into Google im sure somewhere will be a details and screen shots of what to do.

Not what you want to hear I know and the phone must be a fair few years old now! Treat yourself to a new one

The Cisco 7940G and other Cisco's wern't really designed to be configed onscreen with the phone, but to be done through a server and automated tools.

I'd opt for a cheap Grandstream Budgetone 200 for around £46 as a starter phone or a SNOM 360 £100+ for a more feature rich one. Both are easy to setup through a web browser.

What setup are you wanting? Single line or is this to add to a busy office?
