The support from the supplier is now where near acceptable. For security concerns, a newbie is locked out of the system and has to find other ways to get support. We are not all techies this is meant for small business owners who don't have full days to dedicate to this piece of technology!

We use these phones in 3 different businesses and we have the same issue occurring.The phone « external speaker » will fail at one point, so the phones wont ring anymore and you can not use the speaker obviously.This happened at least 3 times so far out of maybe 15 units.

really clear sound ,

I own a VOIP company and these are the only cordless phones we install: our customers love them and we have zero issues with them. Super easy to setup and use

Been looking for a portable sip phone for a while. Having tried 3 different others I wasn’t expecting much. How wrong could I have been. Superb handset super clear and more important where others failed this excelled with volume being really loud for me. Better yet i can plug in my iPhone headphones for headset if I need too.Con: headset connector on bottom so you can’t put on charge if on a call and running low and have headset in at same time. Def buying a 2nd one for the bedroom.
