We have had Lync and an Audio Codes M800 w/ 1 T1 connection back through an Avaya CM6.3 which was somehow "restricting" hosts from holding a conference down to 10-12 users. So 1 host couldn't use up all the T1 connections. We have now upgraded to an M1000 with 3 T1 connections and I can't find where to open up more conferencing lines to our end users. Any guidance appreciated.
