Got my first CME lab going, few quick questions

Hello,

So I picked up two 7940s on eBay for $17 each and a 3550 inline power switch along with 2811 router to start learning Voice. I got the phones registered okay, but I must be missing something as I am not getting dial-tone on either phone.

From the router console I see the phones registered below. From the web interface using /telephony_service.html both phones show up and I can change the welcome message or assign names to the line buttons.

1. Any tips or links on steps to follow to make the phones play a dial-tone ?
2. Would like to be able to call from one phone to the other on the same switch before making it more complex..

I pretty much followed this quick guide to get my feet wet - https://learningnetwork.cisco.com/servlet/JiveServlet/previewBody/6346-102-1-20737/CCNA-Voice%20VoIP.pdf

Doing some searching online I'll need to read about voice register and dial peer

Until we see your running config, hard to say why your phones don't have a dial tone. Your running config will show your ephones, telephony service TFTP etc.

I would install Cisco Configuration Professional and set up your dial plans and check your settings. I learned alot from reverse engineering all the commands that CCP sends to the router. Do you have a FXS card installed in your router? You might be missing the CME_Voice(config-telephony)# auto assign 1 to 4 command.

For setting up CME, a great place to start is the CCNA:Voice Study Guide (1st Ed) for the old IIUC course. It covers CME from beginning to end.

For dial-tone, have you configured ephone's and ephone-dn's?
