Summary: It does not have: On screen configuration. It only gives voice commands so provisioning was a bit of a challenge. A power adapter, so unless you have PoE switch you are going to be shopping for a power adapter like me now. Otherwise - call quality is great and it is an 8 line phone. The write-on insert for the programmed keys looks very stupid.
Wall phone for church nursery/Sunday school. Compared with SPA301 and SPA942

Summary: Background: I'm installing phones in each nursery and classroom at my church. I'm using POE so that the cords can all be in the wall and not a problem for tiny hands. Plus it gives me the freedom to place them where I want with out needing an electrician. Just a drywall saw, some cat5e, a fish tape, and instant phone. At the same time, I'm upgrading the office phone from SPA942s to SPA504s. I had to install 10 of these.
Excerpt: After getting this IP phone to work with any regular SIP provider, it works like a charm. But before getting it to work you will need to do some research on the internet, cause the manual at hand is for end users and not for administering the phone. So after having a rather large search on the internet I was able to maintain a copy of the administrator manual to get it to work properly...
Summary: Very hard to get answers on getting it configured. Not as easy as the more expensive models. Can't just plug and play as advertised. Good voice quality. Rugged, knocked it off the desk 20 times trying to get it configured and still works well. Only bought it to use in testing a new phone system. Would hate to have to use it on a daily basis as it has no display.
