I don’t seem to get the list of participants depicted in the online help or understand how to invite anyone to a conference.
Here is my fop2.cfg:
;Users
user=103:secret1:meetme
user=104:secret2:meetme
user=503:secet3:all:MotherHen
;Groups
group=MotherHen:SIP/503,SIP/103,SIP/104,CONFERENCE/1000
(The contexts for all the users and the conference are allowing normal internal extension-extension calls)
Is this right?

Have I got to configure the meetme.conf in asterisk?

...and set up all the MeetMe exten's in the dailplans?

Now I get it. I can see the list now. I didn't realise you have to get the conferencing working thru asterisk first, I thought fop2 did the conferencing.
