1. A method, comprising:
receiving, during a video conference session to which user devices are connected, a public switched telephone network (PSTN) call from a new user device separate from the user devices;
forwarding caller information associated with the PSTN call from a call switch to an automatic call-to-conference elevation (ACE) application via a first session initiation protocol (SIP) request;
transmitting, to at least one of the user devices, data configured to present, on at least one screen of the at least one of the user devices, a prompt associated with the PSTN call;
establishing a new session leg between the call switch and the ACE application based on a selection associated with the prompt;
transitioning, based on video capabilities of the new user device indicating that the new user device is other than video capable, a connection of the new user device from the PSTN call to the video conference session over the new session leg via a second SIP request that includes a command to bypass an interactive voice response menu otherwise used for the video conference session; and
terminating the PSTN call.
