Excellent Phones! Easy to set up, superb call quality and full support for my asterisk PBX. Did a manual setup on each of these phones as my system is on the smaller size and had the first one up and running in less than 10 minutes, with BLF for all my extensions.

Make sure you only buy this as an add-on to an existing cordless Yealink phone system. It needs the full base unit, this one just charges.

I have bought 5 of these already for my work at home employees. They work great with SIP Systems

I have half a dozen of these deployed for the last year - zero issues. works great.
