ISDN/PSTN Participants

ISDN and PSTN participants can connect to conferences and Meeting Rooms directly or via an Entry Queue by dialing one of the numbers (including the country and area code if needed) assigned to the conference, Meeting Room or Entry Queue. When connecting to an EQ they are routed to their conference according to the conference ID.

For example, if the assigned dial in number is 4045555, the ISDN/PSTN participant dials this number with the appropriate area code (for example, 678) and country code (001).
