Which manufacturers of sip phones and PBXs regularly release firmware?

Question

Telephony

Interested in at least five years of support. And then the offer to buy iron is already being fired, which in a year is already without security fixes. First of all, there is a desire to ignore Android phones. The fourth version is in fashion there))). Interested in Panasonic, but xs as a time with a centralized setting of phones.

Answer 1

I highly recommend Grandstream. Of the 5 pieces, a year later, four of the buttons fell off, and one failed.
Panasonic is the most worthy option from what we have tried. Build quality and materials are unbeatable in this price range. There is a 5 year warranty. There are models for every taste DECT, stationary with a bunch of programmable buttons. They are centrally configured with a bang, they can take the config from the server via FTP\HTTP\TFTP. Our configs are right on the Mikrotik, it sends all the information to the phones and what address to get and where to pick up the settings and give the settings. In general, perfect! Recommend.

Answer 2

Look at Grandstream, I'm not sure about 5 years old, but the products seem to be not bad.

Answer 3

Check out Yealink. Systematically new firmware even for those devices that have already been discontinued.
