One of my clients has been using a WISP for a while now for their business. The service was not good enough to be able to use VOIP. They are now in the process of getting a dedicated fiber internet service for their business. They are paying approx $380 USD for POTS and want to migrate to SIP for obvious reasons. It will be beneficial as they have 1 main office with 7 employees and 2 satellite offices.
They have never had a "real" phone system. The only "feature" they have is CID. No voicemail, nothing. They are currently using RCA 4-line desk phones. I want to get them on FreePBX and some Yealink phones. The ISP is trying to talk them into using their hosted VOIP service but the prices are inflated and you have to lease the phones.
I have only used Yealink DECT cordless phones and would like some recommendations for some basic models. I recall random posts here about some that are best to avoid and some that are great. I would rather have recommendations than buy something based off of reviews on websites like Amazon. I have used/installed Cisco, Grandstream, Polycom, Avaya, and Sangoma, etc. but wish to move to Yealink as they seem like a popular choice lately, and not just on ML.
While working with NTG, I was using the (now EOL) Yealink -T22P and it was a good phone. I added a headset with lifter, and was able to talk from across the house with no trouble.
Will you need single or multi line units?
Yealink has expanded quite a bit since then also, I see they now have models that will integrate with MS Teams.
