Of course it does. However, by their design, mobile devices only support passive screen sharing.

Android. Users of Android tablets or smartphones use the Chrome browser or Firefox.

iOS. Users of iPads or iPhones use Safari (from v11). Users of older iOS versions with Safari 10 cannot receive screen sharing.


The MeetingSphere subscription comes with 'Unlimited participants and meetings' which means that your right to use is not limited to a certain number of meetings or participants.

However, this right to use for 'unlimited participants' does not mean that there are no factual limits to the number of concurrent participants MeetingSphere will support. While MeetingSphere scales well and will support anything most people would use the word 'meeting' for, it is not designed for broadcasting to very large numbers of people. The number of concurrent participants depends very much on the type of meeting you run and, as much as anything, the equipment, and network infrastructure you and your participants use. Moreover, there are limits to the number of users a particular process will serve well, independent of technological scalability. For example, by rule of thumb

  • Voice conferences should be switched to "Mute all/Push-to-talk" when there are more than 8 participants in the 'room'. If lines are good, and everybody is using a headset this number may be higher. If not, you may have to start muting earlier.
  • A dynamic Brainstorm with more than 30 highly energized participants may produce ideas faster than participants can easily follow. In this case, you may want to think of slowing the process regardless of MeetingSphere's technical capacity to handle many more users and contributions.
  • An anytime session i.e. a meeting left open for an extended period of time during which participants can contribute in their own time can handle thousands of participants.
  • A screen sharing session where most participants sit on the same network behind a firewall of inadequate capacity, can be limited by the capacity of that firewall.

'Unlimited meetings' means that you can run an unspecified number of meetings concurrently. For instance, you could run a web conference while you have several meetings open to which participants contribute in their own time (so-called anytime meetings).

In practice, the number of concurrent meetings you can run is limited by two factors:

  1. Your ability to effectively control multiple meetings as you can only 'be' in one meeting at a time.
  2. The voice conference of any given meeting requiring your (the leader's) presence.

MeetingSphere is served from Amazon Web Services (AWS), one of the most comprehensive, highly available and secure data services available today.

  • Customers from the Americas are served from Amazon Virginia (east coast)
  • European, African and Asian customers are served from Amazon's European data center in Ireland (EU).

Data is stored locally meaning that customer data at rest never leaves the AWS region the customer is served from.


MeetingSphere develops and provides its meeting solution in accordance with ISO 27001:2013. Certification is in progress. Security measures include periodical penetration testing by independent experts. For our customers, this means that our processes, software and cloud deployments are hardened and continuously improved to protect the confidentiality, integrity and availability of the service.

MeetingSphere, operates the MeetingSphere service under Amazon's shared responsibility model. Amazon Web Services (AWS) is one of the most highly available and secure data services available today. AWS certifications and audits include: AICPA SOC 1 - 3, PCI DSS Level 1, ISO 27001, FedRAMP, FISMA Moderate, HIPAA, SAS 70 Type II.

If your firewall allows you to connect to the Internet at all, connecting to MeetingSphere should not be a problem.

Devices connect to MeetingSphere via standard port TCP 443 (https). There are very few firewalls which block this most basic of ports.

MeetingSphere's voice conferencing service delivers voice-over-internet via port UDP 60. If this port is blocked by your or a participant's firewall, the voice service falls back to port TCP 443. Should the firewall interdict voice traffic over that port, too, simply dial in via the public telephone network. MeetingSphere provides over 200 'local' land-line numbers, one of them should be near you and each of your participants. There are no conferencing charges.

Locked down computers work just fine if they run a supported browser (see above).

If you use Internet Explorer 11, you must have the privileges to install the add-on for web conferencing.
