I'm trying to configure N-Way Conference call from the example from http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO
When I'm testing it , I'm calling from one extension to another , pressing *0 and ... nothing happens !
From the example , the *0 key needs to open free conference room , move my and the second extensions to that room and then sen me and dial tone to add another extension.
Where could be the problem ? May be Asterisk couldn't recognize the *0 tone ?
