This story starts out with me wanting to configure a Cisco 7940 phone we had for our Call Manager to work with my VOIP provider. I never did get it to work. I ended up with a nice Motorola cordless phone plugged into the ATA device Broadvoice sent me. I have wanted to tinker with getting the Cisco phone to work with SIP for months but didn’t. Truth be told I hadn’t really put much effort into it until today. After tinkering with some TFTP files and some firmware updates from Cisco I was able to convert the phone over to SIP. This enabled me to order the Broadvoice service without needing the ATA adapter.

I have been happy enough with my BroadVoice account that I signed my company up for one. We have a POTS line in our cage in our data center. It costs $50 a month for the dam thing. We use it like 4 times a month. The problem is that it is a life saver to have when calling in a server or communicating a problem to others from the data center. Broadvoice’s plan for $10 a month was too good a savings to pass up. I was able to get the phone configured in 10 minutes after I got the SIP firmware on it. Now all we need to do is move the phone to our data center and setup a firewall rule to allow it to work.
