[Synopsis]
Set a custom dynamic bridge and user profile on a channel for the ConfBridge
application using the same options defined in confbridge.conf. 

[Description]
---- Example 1 ----
In this example the custom set user profile on this channel will automatically
be used by the ConfBridge app.
exten => 1,1,Answer() 
exten => 1,n,Set(CONFBRIDGE(user,announce_join_leave)=yes)
exten => 1,n,Set(CONFBRIDGE(user,startmuted)=yes)
exten => 1,n,ConfBridge(1) 
---- Example 2 ----
This example shows how to use a predefined user or bridge profile in
confbridge.conf as a template for a dynamic profile. Here we make a admin
/marked user out of the default_user profile that is already defined in
confbridge.conf.
exten => 1,1,Answer() 
exten => 1,n,Set(CONFBRIDGE(user,template)=default_user)
exten => 1,n,Set(CONFBRIDGE(user,admin)=yes)
exten => 1,n,Set(CONFBRIDGE(user,marked)=yes)
exten => 1,n,ConfBridge(1)
