Issues
While this phone works well with asterisk, we have had issues with the speakerphone and echoing. After spending quite a bit of time trying to sort out echo settings in Asterisk, we resorted to inserting foam in the phone to limit the amount of leakage from the phone’s speaker into the microphone. This drastically increased the quality of the speakerphone function

I’m sure we are out of warranty now… –mogmismo
Setup with Asterisk
The easiest way to configure it is through the web interface at http://device.ip.address:9999 there is no username or password set by default so clicking OK should be enough to log in.
Make sure you set your timezone and NTP server. I recommend time.nist.gov.
Under SIP Settings you should put your server ip where is required. MAKE SURE YOU USE *[email protected] on the box labeled “Voice Message Account” otherwise you will get an error when you try to use the voicemail dedicated button.
Set all the other parameters depending on your server, reboot and enjoy!
