[help]about a feature

In our old system(isdn telephone), we can configure some function (like telephone transfer) direct on the telephone or through the administrator software, is it also possible by asterisk and IP-telephone?

Asterisk configuration and IP Softphone/Hardphone are independent, therefore the Asterisk configuration may not configure features directly on the handsets. Having said this, there are ways of providing class of service and other facilities via the Asterisk dialplan.
