DID in a confbridge

hi,

i configured confbridge and it worked right, but know i like to put a DID for this conference, how i make that? please, teach me with detail

The same way as your route a DID to any other extension. For detail expect to pay consultancy rates.

[confbridge-did]
exten=>_x.,1,Answer()
same=>n,ConfBridge(${EXTEN},1234_participants,1234_menu)

exten => _x.,1,Progress()
same => n,n,Wait(1)
same => n,n,ConfBridge(1,default_bridge,default_user)

whats this “_x.” means?

i want a DID for external cell phones (not users of my pbx) can make a call

The letter X or x represents a single digit from 0 to 9. for moe details read

X does, but x represents x.
