For IP Office systems, the answer varies as the conferencing is performed by the system rather than the phone.
Conferences can be up to 64 parties or larger (depends on the type of server running the IP Office software). Note that may be reduced by the number of conferences already in progress at any time,
For the phones in the J100 Series, first, separate the J129 from the others phones as it works differently.
For the J129, if using the phones menus for conferencing it can only host its own local 3 party conference on the phone. If using the IP Office system shortcodes, it can be in much larger conferences (though its a really pain to do).
For the others, J139/J159/J179, they can easily create conferences up to the system limit through the phone menus and display details of who is in the conference, etc.
