Systems and methods for a conferencing system. Responsive to a new conference request received at a conference orchestration service, participants of the conference and participant regions for each determined participant are determined. A mixer topology is generated that specifies an assignment of each determined participant to at least one input channel of a plurality of mixers. A mixer state manager generates the mixer topology based on the determined participant regions and at least one regional association of a mixer. Media of each determined participant is routed to the assigned at least one input channel according to the generated mixer topology by using the conference orchestration service. The mixer state manager generates the topology responsive to a request provided by the conference state manager. The conference orchestration service receives the generated mixer topology from the mixer state manager via the conference state manager.

1. A method comprising: at a conferencing system that includes a conference state manager, a conference orchestration service, a mixer state manager, and a plurality of mixers: one of the conference state manager and the conference orchestration service determining at least one participant of a conference and a respective participant region of each determined participant responsive to a request for a new conference received from an external system via an interface of the conferencing system, wherein one of the conference state manager and the conference orchestration service determines the participant region of a participant based on at least one of an area code and a country code of an endpoint of the participant;responsive to determination of the at least one participant and the respective participant region by the conferencing system, the conference state manager providing an application layer request to the mixer state manager via an application layer interface of the mixer state manager, wherein the application layer request includes conference state that identifies each determined participant and a participant region for each determined participant;responsive to the application layer request provided by the conference state manager, the mixer state manager generating a mixer topology by: identifying each determined participant and corresponding participant region specified by the conference state provided by the conference state manger,for each determined participant identified by the conference state: determining a mixer of the plurality of mixers that is located in a region that matches the participant region of the determined participant, and assigning the determined participant to a free input channel of the mixer located in the matching region, wherein the mixer state manager manages mixer state information that specifies for each mixer of the plurality of mixers of the conferencing system a regional association and each free input channel of the mixer, and wherein the generated mixer topology specifies the assigned input channel for each determined participant,responsive to generation of the mixer topology, the mixer state manager providing the conference orchestration service with the generated mixer topology via an application layer interface of the conference state manger,responsive to the generated mixer topology, the conference orchestration service negotiating media across the mixers of the assigned input channels by establishing the mixer topology and starting the conference, wherein establishing the mixer topology comprises: for each determined participant: the conference orchestration service determining the assigned input channel as indicated by the generated mixer topology; andthe conference orchestration service providing a SIP INVITE message to the mixer of the assigned input channel, wherein the SIP INVITE message specifies the determined participant, a mixer identifier of the mixer of the assigned input channel, and a channel identifier of the assigned input channel. 2. The method of claim 1, wherein the conferencing system is a conferencing system of a communication platform, and the conference orchestration service receives the request for the new conference from a call router of the communication platform via a signaling protocol communication interface of the conference orchestration service. 3. The method of claim 1, wherein participants include at least one of: a participant transferred from an established communication session into the conference;a participant that establishes a communication session with an endpoint that is mapped to the conference; anda participant specified by an API request received by an application layer interface of the conferencing system. 4. The method of claim 1, wherein the conference state manager is constructed to maintain conference state of the conference, and to notify the conference orchestration service of conference state changes via an application layer communication interface. 5. The method of claim 1, wherein determining participants of the conference comprises: identifying participants specified in at least one of an application layer request and an application layer response received via an application layer interface. 6. The method of claim 1, wherein determining participants of the conference comprises: identifying participants specified in at least one conference request received via a signaling protocol communication interface of the conference orchestration service. 7. The method of claim 1, wherein the mixer state manager assigns each determined participant to at least one input channel based on respective participant priority values. 8. The method of claim 1, wherein responsive to an application layer request provided by the conference orchestration service, the conference state manger generates conference state of the conference based on information of the application layer request, and wherein the generated conference state includes the determined participants and the determined participant regions of the participants for the conference. 9. The method of claim 1, wherein assigned input channels include input channels of mixers located in different regions. 10. The method of claim 9, wherein the conference orchestration service determines the participants of the conference, wherein the conference orchestration service provides information identifying the determined participants to the conference state manger via an application layer interface of the conference state manager, and wherein responsive to the information identifying the determined participants, the conference state manager provides the application layer request, which specifies the determined participants, to the mixer state manager. 11. The method of claim 10, wherein during the conference, the conferencing system transitions the mixer topology into a transitioned mixer topology according to new conditions, and responsive to transitioning of the mixer topology, the conference orchestration service negotiating media across the mixers of the assigned input channels of the transitioned mixer topology. 12. The method of claim 11, wherein in a case where the mixer state manager determines that a first mixer does not have capacity for participants of the conference, the mixer state manager assigns an output channel of the first mixer to a free input channel of a second mixer. 13. The method of claim 12, wherein the first mixer and the second mixer are located in the same region. 14. The method of claim 11, wherein determined participant regions include a first region and a second region, and the mixer state manager assigns an output channel of a mixer of the first region to a free input channel of a mixer of the second region, and wherein an output channel of the mixer of the second region provides a mixed conference media stream to participants of the second region. 15. The method of claim 11, wherein each SIP INVITE message specifies the respective participant in a SIP “From” header”. 16. The method of claim 11, wherein each application layer request is an HTTP request and wherein each application layer interface is an HTTP interface.
