A computer-implemented method, comprising:
- connecting a first computing device to a virtual private network (VPN) established by a server;
- establishing Voice Over Internet Protocol (VOIP) communications between the first computing device, a second computing device, and a third computing device over the VPN via a Session Initiation Protocol (SIP);
- wherein the first computing device maintains concurrent VOIP communications via the SIP with the second computing device and the third computing device, receives packetized audio from the second computing device and from the third computing device via the VOIP communications, and transcribes automatically the audio in real-time;
- wherein the first computing device is operable to mute either the second computing device or the third computing device, and to continue automatically transcribing speech from a user of the second computing device or the third computing device that was not muted.
