The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Cisco 7940 - Stopped working "Protocol Application Invalid"

Asked by gisvpn in Networking Hardware

Tags: cisco, 7940, bootup

Hello,

I have a Cisco 7940 phone which was configured to use a SIP VOIP provider (voipfone.co.uk) and worked great for just under a year and it has suddenly stopped working.

When the phone boots up now it say...
........ Configuring VLAN
........ Configuring IP
Then says "Protocol Application Invalid" (see image below)...

It is strange as this is the first time I have seen this error and the phone was working fine before for ages. I have a small office set up which uses a switch and Netgear DG843G router (which is also acts as a DHCP server).

I have tried a factory reset (which it responds to) and it restarts but keeps appearing with the same error message.

Any ideas on what I may be able to do to get the phone working ?

Thanks,

GISVPN
