I have an asterisk-17.4.0 install on fedora32 with a Digium A4B 4-port card connected with a single Optonline landline and a Voicepulse SIP account. We are closing our satellite office and have a few Polycom VoIP phones currently connected to the asterisk system.
Currently the satellite office is connected to the main office with a libreswan VPN that the phones use to connect to the main office and the Optonline landline.
I’d like to know what softphone options exist for connecting Windows desktops and laptops to our home office or how to otherwise utilize our Voicepulse account without the need to first connect to our asterisk box at the main office.
Many years ago we had set up a VPN client running on each remote desktop/laptop back to the office, but is that still necessary?
What options exist for connecting our Polycom phones from a remote location?
