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 Vlan's, DHCP, VOIP issue

Asked by ipena in Network Switches & Hubs, Network Routers, Voice Over IP

Tags: , , ,

I am setting up a shoretel phone system and currently have Vlan 1 for the Data and Vlan 20 for the voice side.  I can get everything to work fine if I hard code the ip info into the phone however I cant get it to boot up utilizing DHCP.
When I plug the phone in it boots up into Vlan1 gets its DHCP info then re-boots into Vlan20 however,  the phone stays at a DHCP boot up screen "DHPC xxx Seconds".  What is weird is that I can see on the DHCP server that the phone has been issued an IP address from the Voice Vlan 20.   I hope all of this makes sense, I will also include the configs from the switch and router and a network diagram.   Thanks in advance for your help with this.
