A collaboration service can be aware of portable devices in a conference room that is an endpoint for a video conference, and learn of identities associated with the portable devices present in the conference room. After the video conference is initiated in the conference room, all devices that are in communication with the collaboration service can also be automatically joined to the conference. Since all conference participants in the conference room have their own portable device that is joined to the conference the portable devices in the conference room act as a second screen available to the video conference. As such video from the conference can be directed to a common conference room display, while conference materials can be displayed separately on the portable devices. Additionally, each conference participant's identity can be added to a conference participant roster automatically. ## Claims ### Claim 1 A computer-implemented method comprising: receiving, at a collaboration service, information regarding a first identity from a first device present in a conference room, and information regarding a second identity from a second device present in the conference room; receiving a request to initiate a conference in the conference room from the first device; determining that the first identity and the second identity are both supposed to be in the conference; and automatically joining the second device to the conference without sending audio to the second device based on the determining that the first identity and the second identity are both supposed to be in the conference, the second device joined to the conference without any action taken using the second device to join the conference, the second device joined to the conference without sending the audio to the second device to avoid a feedback loop with audio equipment in the conference room. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the second device is joined to the conference upon learning that the first device is in the conference. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the second device is paired with a conference room device. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein the first device is a conference room device. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the first device is a portable computing device associated with a conference participant. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein the request to initiate the conference occurs prior to the receiving of the information from the second device present in the conference room. ### Claim 7 (depends on 3) The computer-implemented method of claim 3, comprising: determining that the second device is no longer paired with the conference room device; and presenting a prompt on the second device that is no longer paired with the conference room device, the prompt asking whether the conference should be continued or ended for the second device. ### Claim 8 (depends on 2) The computer-implemented method of claim 2, comprising: sending by the collaboration service to each of the first device and the second device a conference roster, the conference roster including information describing that the first and second devices are in a same location. ### Claim 9 (depends on 1) The computer-implemented method of claim 1, comprising: sending, by the collaboration service to each of the first device and the second device, conference materials being presented in the conference. ### Claim 10 (depends on 1) The computer-implemented method of claim 1, comprising: sending, by the collaboration service to a display in the conference room, at least one of video or audio of a speaker at a same time as sending conference materials being presented in the conference. ### Claim 11 (depends on 1) The computer-implemented method of claim 1, comprising: presenting a prompt to the second device requesting confirmation that the second device should be joined to the conference. ### Claim 12 A non-transitory computer readable medium comprising instructions stored thereon, the instructions effective to cause a computing system to: determine that a client device is paired to a conference room device that is in a conference room; receive information regarding a first identity and a client device identifier for the client device paired to the conference room device; determine that the first identity is invited to a conference taking place in the conference room; and automatically join the client device to the conference without sending audio to the client device if the first identity is invited to the conference taking place in the conference room, the client device joined to the conference without any action taken using the client device to join the conference, the client device joined to the conference without sending the audio to the client device to avoid a feedback loop with audio equipment in the conference room. ### Claim 13 (depends on 12) The non-transitory computer readable medium of claim 12, wherein the instructions are effective to cause the computing system to: add to a conference roster of the conference the first identity from the client device that was automatically joined. ### Claim 14 (depends on 12) The non-transitory computer readable medium of claim 12, wherein the conference was initiated prior to receiving the information. ### Claim 15 (depends on 12) The non-transitory computer readable medium of claim 12, wherein the instructions are effective to cause the computing system to: send conference materials being presented in the conference to the client device; and at a same time as the sending the conference materials being presented in the conference, send video of a speaker to a display in the conference room. ### Claim 16 A system comprising: a pairing service to pair a client device to a conference room device in a conference room; a conferencing service to receive information regarding a first identity associated with the client device paired to the conference room device; and a scheduling service to determine that the first identity is invited to a conference taking place in the conference room, wherein, the conferencing service is configured to automatically join the client device to the conference room device without sending audio to the client device if the scheduling service determines that the first identity is invited to the conference taking place in the conference room, the conferencing service is configured to automatically join the client device to the conference room device without any action taken using the client device to join the conference room device, and the conferencing service is configured to automatically join the client device to the conference room device without sending audio to the client device to avoid a feedback loop with audio equipment in the conference room. ### Claim 17 (depends on 16) The system of claim 16, wherein the conferencing service is to add the first identity to a conference roster of the conference. ### Claim 18 (depends on 16) The system of claim 16, wherein the pairing service is configured to determine that client device is no longer paired with the conference room device; and wherein the conference service is configured to send a prompt to the client device asking whether the conference should be continued or ended for the client device if the client device is determined to no longer be paired with the conference room device. ### Claim 19 (depends on 16) The system of claim 16, wherein the conference service is to send conference materials being presented in the conference to the client device, and at a same time as the sending the conference materials being presented in the conference, send video of a speaker to a display in the conference room.
