[GnomeMeeting-list] Calling a Netmeeting-user

[Harald <harald wanadoo nl>]

Hi,

If I am right, with Netmeeting you can call someone just using the
hotmail-address of the other registered Netmeeting-user. 

Is that also possible with Gnomemeeting?
So, can I, using Gnomemeeting, call een Netmeeting-user just using
his/her hotmail-address?

If yes, how do I have to use it?

Like this?
callto:user hotmail com

With kind regards,
Harald
