Videoconference content sharing for public switched telephone network participants

A computer-implemented method comprising:

• hosting, by a conferencing service, a videoconference among a plurality of participants, wherein the plurality of participants comprise Internet Protocol (IP)-connected participants and a Public Switched Telephone Network (PSTN)-connected participant, wherein the IP-connected participants are connected to the videoconference via IP-based connections, wherein the IP-connected participants send and receive audio content of the videoconference and video content of the videoconference via the IP-based connections, wherein the PSTN-connected participant is connected to the videoconference via a PSTN connection, wherein the PSTN-connected participant sends and receives the audio content of the videoconference via the PSTN connection;
• monitoring the videoconference to detect that a first video status change event occurs within the videoconference;
• selecting, by the conferencing service, based on the first video status change event, an image corresponding to a portion of the video content of the videoconference for transmission to a first device associated with the PSTN-connected participant;
• and
• transmitting, by the conferencing service, the image to the first device.

One or more non-transitory computer-readable storage media having stored thereon computing instructions that, upon execution by one or more computing devices, cause the one or more computing devices to perform computing operations comprising:

• hosting, by a conferencing service, a videoconference among a plurality of participants, wherein the plurality of participants comprise Internet Protocol (IP)-connected participants and a Public Switched Telephone Network (PSTN)-connected participant, wherein the IP-connected participants are connected to the videoconference via IP-based connections, wherein the IP-connected participants send and receive audio content of the videoconference and video content of the videoconference via the IP-based connections, wherein the PSTN-connected participant is connected to the videoconference via a PSTN connection, wherein the PSTN-connected participant sends and receives the audio content of the videoconference via the PSTN connection;
• monitoring the videoconference to detect that a first video status change event occurs within the videoconference;
• selecting, by the conferencing service, based on the first video status change event, an image corresponding to a portion of the video content of the videoconference for transmission to a first device associated with the PSTN-connected participant;
• and
• transmitting, by the conferencing service, the image to the first device.
