I created an extension 200 and then tried to dial 8200 from a sip client logged in as extension 201, but was given a message saying I had dialed an invalid conference number. Is it possible the <username>-<extension> format you are using stops this from working properly? Maybe I just set it up wrong.
Sorry to bump this post, but I haven't really had time to work with this more until now. I looked at the instructions and can't really find any reason this doesn't work.
According to the instructions I find this:
8<extension> Conference
Each extension you create will have its own conference. For example extension 200 has conference 8200. Just dial 8200 to get into your conference. Add participants by transferring them to 8200. The first participant will hear on hold music.
So I created two extensions 200 and 201. I connect to extension 200 and dial 8200. Then the voice tells me "That is not a vaild conference number."
