Aastra phone on the 5000/250

[Curtis-at-Travis]

In our office, we have a couple of boxes of Aastra phones that we had to take back from a cloud customer. 
On a whim, I decided to see how difficult it would be to install one on our phone system.
It took 10 minutes.
Using just the keypad interface.
In the phone system, I created a SIP phone, and programmed the Inbound Authentication in the SIP profile with the Extension number, and a password.
On the phone itself, I set up the SIP connection with the Proxy Server and the Registration Server both set to the IP address of the phone system, and the Phone Number,Caller ID, and Authentication Name to be the extension of the phone, and the password to be the authentication password set up in the phone system.

Boom, it was done.

The model I installed was the 6867i

I really like the look and feel of this phone.  It doesn't have full features, but in some scenarios, I can see this being very handy. And since we have incentive to get these devices off of our shelf, I can see us undercutting Amazon and other internet stores for customers interested in a cheap "IP phone".

It's always a good feeling when you get unsupported hardware to work the way you want.
I had a similar story from the past week- Customer was going from a hosted solution to an on-premise PBX because of complaints of dropped calls. I got their Aastra 6757i phones to work on a FortiVoice. Only feature I could confirm as not working was the message waiting indicator, so I just setup voicemail-to-email and no one even notices the difference.
