Hello, I am wanting to replace an analog wireless phone system (Panasonic KX-TG4000B) with an IP LAN solution. I have 4 PSTN lines total that will eventually be needed to hookup to the system. While I want to take advantage of VoIP features, my PSTN lines are very cost effective and I don't want to switch to VoIP across the Internet yet; I just want to use IP phones and soft clients at the house and use the inbound and outbound calling across three of the lines. The fourth one is a fax line. Fax to email, soft clients, etc are very intriguing. However, is 3CX a good solution for me and if so, which PSTN Gateway does the community recommend. Thanks.
