A communication collaboration system, comprising: a memory storing machine readable instructions to: initiate a communication session upon user authentification based on a user-specific user ID and password, the communication session comprising communication via video from a first video endpoint to a second video endpoint (252, 253), the communication including a first signal in a first video format; receive (301,401) the first signal, the first signal representing a first mode of communication for the user; and seamlessly transition, that is, without the user having to repeat identifying information, from the first mode of communication for the user to a second mode of communication for the user while maintaining the communication session, wherein the second mode of communication is different from the first mode of communication, and wherein seamlessly transitioning from the first mode of communication for the user to the second mode of communication for the user further comprises machine readable instructions to: - launch a new communication channel on each of the video endpoints (251, 252, 253) before converting the first video format, and - convert the first signal from a first video format associated with the first mode of communication to a second video format associated with the second mode of communication by separating signaling data from video content and passing the video content through a transcoder; and a processor to implement the machine readable instructions. initiate a communication session upon user authentification based on a user-specific user ID and password, the communication session comprising communication via video from a first video endpoint to a second video endpoint (252, 253), the communication including a first signal in a first video format; receive (301,401) the first signal, the first signal representing a first mode of communication for the user; and seamlessly transition, that is, without the user having to repeat identifying information, from the first mode of communication for the user to a second mode of communication for the user while maintaining the communication session, wherein the second mode of communication is different from the first mode of communication, and wherein seamlessly transitioning from the first mode of communication for the user to the second mode of communication for the user further comprises machine readable instructions to: - launch a new communication channel on each of the video endpoints (251, 252, 253) before converting the first video format, and - convert the first signal from a first video format associated with the first mode of communication to a second video format associated with the second mode of communication by separating signaling data from video content and passing the video content through a transcoder; and - launch a new communication channel on each of the video endpoints (251, 252, 253) before converting the first video format, and - convert the first signal from a first video format associated with the first mode of communication to a second video format associated with the second mode of communication by separating signaling data from video content and passing the video content through a transcoder; and a processor to implement the machine readable instructions.
