Systems and methods for asynchronously joining and leaving video conferences and merging multiple video conferences

1. A computer-implemented method for open video conference calling, the method comprising:

receiving a request to initiate a first video conference call from a caller to one or more called parties;

verifying an identity of the non-participant before allowing the non-participant to join the video conference;

receiving an acceptance of the first video conference call by at least one of the one or more called parties;

responsive to receiving the acceptance of the first video conference call, establishing a video conference between the caller and the accepting one or more called parties;

identifying the caller and the accepting one or more called parties as participants of the video conference;

during the video conference, receiving a request to initiate a second video conference call between a first participant and a non-participant of the video conference;

verifying an identity of the non-participant before allowing the non-participant to join the video conference;

receiving an acceptance of the second video conference call between the first participant and the non-participant;

receiving an instruction from the first participant to limit participation rights in the video conference of the non-participant, the instruction from the first participant comprising limiting access of the non-participant to media content presented in the video conference prior to the non-participant joining the video conference;

responsive to receiving the acceptance of the second video conference call, the non-participant joining the video conference subject to the instruction from the first participant to limit the participation rights in the video conference; and

responsive to the non-participant joining the video conference, notifying the participants that the non-participant has joined the first video conference.

2. The computer-implemented method of claim 1 , wherein the request to initiate the second video conference call is received from the first participant.

3. The computer-implemented method of claim 1 , wherein the non-participant joining the video conference further comprises establishing a video conference connection between the second video conference call and the first video conference.

4. The computer-implemented method of claim 1 , wherein the request to initiate the second video conference call is received from the non-participant.

5. The computer-implemented method of claim 1 , wherein the non-participant of the video conference is participating in at least one first separate, pre-existing video conference.

6. The computer-implemented method of claim 5 , wherein the at least one first separate, pre-existing video conference includes at least one additional participant in at least one additional video conference.

7. The computer-implemented method of claim 5 , wherein the request to initiate the second video conference is received from the non-participant by one or more of the participants in the existing video conference.

8. The computer-implemented method of claim 1 , wherein at least one of the called parties of the first video conference is a participant in at least one second, separate, pre-existing video conference.

9. The computer-implemented method of claim 1 , wherein at least one of the called parties of the first video conference is a participant in at least one second, separate, pre-existing video conference.

10. The computer-implemented method of claim 1 , wherein the request to initiate the second video conference is received from the participant in the conference call, the participant also requesting to initiate at least one more video conference call.

11. The computer-implemented method of claim 1 , further comprising validating port information of a client device of the non-participant.

12. The computer-implemented method of claim 1 , further comprising receiving an instruction from a second participant of the video conference prohibiting the non-participant from joining the video conference.

13. The computer-implemented method of claim 12 , further comprising verifying an identity of the non-participant before allowing the non-participant to join the video conference.

14. The computer-implemented method of claim 12 , further comprising validating port information of a client device of the non-participant.

15. The computer-implemented method of claim 1 , further comprising receiving an instruction from a third participant to leave the video conference before the video conference is terminated.

16. The computer-implemented method of claim 15 , further comprising receiving an instruction from the third participant to rejoin the video conference.

17. The computer-implemented method of claim 16 , further comprising receiving an instruction from a remaining participant preventing the third participant from rejoining the video conference.

18. The computer-implemented method of claim 1 , wherein the instruction from the first participant to limit participation rights in the video conference of the non-participant comprises limiting access of the non-participant to media content presented in the video conference prior to the non-participant joining the video conference.

19. A computer-implemented method for open video conference calling, the method comprising:

establishing a video conference between at least two participants;

during the video conference, receiving a request to initiate a video conference call between a first participant and a non-participant of the video conference;

verifying an identity of the non-participant before allowing the non-participant to join the video conference;

receiving an acceptance of the video conference call between the first participant and the non-participant;

receiving an instruction from the first participant to limit participation rights of the non-participant, the instruction from the first participant comprising limiting access of the non-participant to media content presented in the video conference prior to the non-participant joining the video conference;

joining the second video conference call with the video conference to establish a combined video conference, the participation rights of the non-participant in the combined video conference limited based on the instruction from the first participant; and

responsive to the non-participant joining the video conference, notifying the participants that the non-participant has joined the first video conference.
