Product Reviews
Rated 4.1 out of 5 by 16reviewers.
Rated 5 out of 5 by Great phones, have provisioned quite a few of these with Asterisk PBX servers and also 3CX PBX and they work really well. What the users like about this model compared to the newer Aastra models with colour displays is that this model has really large easy to see screen.Haven't encountered any issues with them so far. May 17, 2016
Rated 4 out of 5 by Great features for the price. Sound quality is excellent. No issues with them so far. Have an issue with the scanning correctly in spiceworks, but that is not a major issue. June 16, 2015
Rated 5 out of 5 by Great phone, easy to use and setup. Highly customisable. POE is a really nice feature, plus the built in switch. October 14, 2013
Rated 1 out of 5 by Yeah.. No. This pretty little deskset has a nasty habit of dropping calls for no reason. We dug into it and found others reporting that if the network has quite a bit of broadcast traffic, the phone drops out.This one and the one we replaced thinking it was faulty, both acted like this. All other IP phones from various vendors that we've tested or have in production do NOT behave like this.Boo! December 4, 2012
Rated 5 out of 5 by Awesome phones. Clarity, XML scripting etc...6739i is really nice also... January 27, 2012
Rated 4 out of 5 by This is a good product, does an awesome job. Only problem we have is they do not pick up the directory configs and we have to pull the power on them to get it to update at times. otherwise awesome product! January 23, 2012
Rated 5 out of 5 by I can't speak highly enough of the Aastra 6757i. We deployed 80 of them over a year ago and haven't had a problem since. The XML scripts which manage the GUI make my job 10x easier than when we were running on analog devices. October 11, 2011
Rated 4 out of 5 by Simple with good features. Easy to setup and maintain. Good sound quality. Great price! March 20, 2011
