Great phone, excellent features, great value.

The Aastra 57i is the phone we recommend over other phones. If you need a to program a feature a specific way, Aastras are the best to accomplish it and the 57i is an attractive well designed large LED phone. Excellent all around

One of the best IP phones sold today.
Reviewed by Richard Harris on 2/12/09
We use a few different manufacturers of IP phones for our Asterisk IP-PBX, and a few models of each. Our favorite is the Aastra, and specifically the 57i. The standard features on the 57i, along with the ability to customize button mappings and create new feature sets, are the best. Support on the phone is excellent, as well. The quality of the LCD, and its size and brightness is very good. Customers like the Aastra and my experience has been that once they use this phone they stay with it and when they have had mixed phone types end up prefering the 57i.

Aastra 57i Great Phone but needs better support
Reviewed by Jeff Mattson on 2/8/09
We purchase three 51i, four 57i and one 57iCT phones for our small business. Phones are connected to a Sangoma 600 FXS/FXO card in a Phoneboch 1U server.
Love the phones, but found them to be difficult to program and the scripts provided through Trixbox do not work as well as I feel they should. We want to use the day/night feature of the phone. Installed the script but it did not work without some extensive investigation into setup tweaking. Finally got it to work but it worked on only 4 of 5 phones. Then 2 days later day/night did not work again. We have decided to achieve the same goal using Trxibox program rather than spend our time dealing with Aastra scripts.
Aastra does not support the scripts and without the scripts the phone does not do all that they claim it does.
A big problem is figuring out what is controlled by Trixbox and what is controlled by the phones.
By the way, called Aastra support to figure out some issues with the phones. Save yourself the trouble, the advice we got was wrong and the gal on the phone did not seem to know what she was doing. Little to no help. We solve the problems on our own. Thankyou for nothing Aastra!
