Can somebody make some recommendations for a good wireless phone system that easily connects to 3CX and provides good audio? It should also include a speaker phone and we would like to have an option to use up to 4 devices in the future. I have already looked at the Yealink W56P or, the older version, the Yealink W52P. Are those easy to connect? Do they support auto-provisioning? What about a similar offering from SNOM? Any recommendations? What models aren't recommended? Any feedback is appreciated. Thank you!
