Meetme - how-to avoid playback of conference number

Hi guys. Need help on Meetme.
Does anybody knows how to avoid asterisk say “You’r enterning conference number …” when you first enter into a dynamic conference?
I mean, if I use the “d” and “E” option in Meetme command, the conference is created on the fly, without pin, and the channel is transferred to that conference. You are not prompted to enter conference number nor a pin, but I can’t understand how to avoid the playback of the conference number.

This is the code i use in dialplan
exten => 9999,1,NoOp
exten => 9999,n,MeetMe(80080,1qdE)
exten => 9999,n,Hangup

Please help :smile:
