📞 Improved Communication with Yealink SIP-T20 IP Phone: 2-Line HD Voice for Non-PoE Environments Review

Very basic VOIP phone. The two-line system is very confusing. Especially if you have 5 lines :-( The reason I gave it one star is because this phone that was sent to me came preloaded with the watch's Fonality firmware to remove it and the Formality didn't help (since I'm not a customer) So now I have a $40 paperweight.

I bought it and very easily set it up as a SIP phone with our VOIP account. Everything was fine until a few days later I started receiving these strange calls from very strange caller ID numbers. A little research showed that by default this mode is vulnerable to random calls trying to find security flaws. I was able to download and apply the latest software update and the issue was resolved. Otherwise it is a very good phone with great sound quality. highlighted.

I actually purchased this product and expected problems. It sounds very strange, but I tested the PBX VOIP software (Kerio Operator, a product I sell) that can automatically adjust the number of stamps. Because I wanted to REVIEW I wanted a phone I didn't know about to see how difficult it would be. Well, it turned out to be trivial. The web browser configuration was quick - I haven't even read the manual so I know there are other features I'm not even aware of but the phone works. Looks solid…
