Client and network

Browsers and mobile devices connect to the MeetingSphere service via standard port TCP 443 (https). The voice service uses port UDP 60 falling back to TCP 443 if that port is blocked.

Users on a slow line, lacking a headset or unable to connect over the Internet for whatever reason dial into the voice conference via the telephone network (PSTN). MeetingSphere offers over 200 'local' (land-line) numbers.

There are no conferencing charges.
