david.wild · ‎11-26-2010

HI All,

All of the ad-hoc DNs need to have the same number, so that they are all potential matches for the conference session.

Configure all three DNs to have 'number 3500'. That will give you an overlay of 6 channels (3 x dual line) and allow for a single 6 party conference. With your current config, it only allowes for three 2 party conferences (which a 2 party conference doesn't really exist since it's just a unicast call).

Thanks Steven i will give that a whirl. I saw a config with the numbers the same but didn't see the relevance of it. as far as i can see everything else looks good but this is the first time i have ever had to do this on a CME.

Watch this space.

Thanks Dave
