Nokia Team Suite is one of the application that have been made available for e-series Nokia phone via catalogs. Its main purpose is to facilitates group communications. You can setup groups, similar to the Caller Groups in the regular contacts app, but from there you also have a plethora of options, available in a customisable side bar. Once you setup your group (and you can have as many as you wish), from the Nokia Team Suite you can do the following:

• Call all the members in a conference call (depending on how many your service provider supports)
• Create a message (sms, mms, or email)
• View their webpages
• Initiate a PTT session
• Call a conference calling service. With this one also, you can preset the service's number and PIN and all that, making it easy if you frequent sit in on a conference call with the same people.
