Abstract: A device may receive, from a user device, a request to establish a voice call. The device may determine that one of a plurality of endpoints is to be involved in the voice call with the user device. The device may transmit send-only invites to the plurality of endpoints. The device may receive, from a first endpoint of the plurality of endpoints, a receive-only response. The device may transmit a send-receive invite to the first endpoint, wherein the send-receive invite identifies a selected communication protocol as a communication protocol for the voice call. The device may transmit a send-receive acceptance to the user device. The send-receive acceptance may identify the communication protocol for the voice call, and upon the user device receiving the send-receive acceptance, the voice call can be established between the user device and the first endpoint.
