atcomsystems.ca/forum Forums TDM Business Telephone Systems Nortel Telephones & Systems Connecting conferencing speakerphone to Nortel phone system

Yes it says in manual that this speakerphone is analog, but I thought that Nortel is analog too. Can you recommended some analog terminal adapter ?
One more think. I can see now in manual that says “do not connect on multi-line system” I guess this is multi-line system. What I should do about this issue? Should I set deducible line ? how to do that?

Thanks a bunch for your help
