We are in the process of migrating our remaining legacy phones to IP Phones with callmanger 7. For this project I need to get a replacement for our legacy 48 port audio conference bridge that is part of the old legacy phone system. Cisco recomends Meetingplace for this, but I really only need basic audio conferencing (for both inside and outside callers). What other options are there other than meetingplace or meetingplace express for this? I'm trying to do this as cost effective as possible.
