The daily standup meeting in agile remains the same, that is, 15 minutes, where the team meets, talks about the three questions. Any further discussion will be a part of the SIDEBAR, that’s it! “For teams that share work between TIME zones, stand-up is a great time to pass the baton as the team which is coming online can pick up right where the other team had left off. And holding stand-up via video conference makes it easy to ask questions and get up to speed so everyone is off and running as soon as the meeting is done.” - Atlassian

This applies to all the Agile/Scrum teams whether they are co-located or distributed, the scrum events remain the same. With distributed teams, there is just a small difference – they use video conferencing for sprint BOARD sharing (if no online TOOL is being used). But if the teams are using tools like Version 1 or Rally or any other tool, they can simply use a dial-in number to connect with each other. There are multiple PLATFORMS like Skype which can be used to bring together the teams. Here, the Scrum Master can come up with creative ways of working with distributed teams, like - coordinating across time zones, building a relationship when everybody is not in the same office, working together among different development cultures.
