How to Accommodate All Conference Invitees

Internal attendees usually join online meetings from their computer or from their smartphone (using a conference app).

But what about invitees who don’t have the app or may not have Internet access for the meeting? To make sure you can reach all invitees, Office 365 Phone System offers a public switched telephone network (PSTN) option, so invitees can call in from a desk phone.

Office 365 Phone System with PSTN Conferencing Bridges a Gap By:

Providing invitees with the option of calling from a desk phone

Accounting for an attendee’s poor or nonexistent Internet access

Making sure all new client or prospect invitees can attend the meeting

Including all potential attendees in your “join the meeting” instructions

Branding your organization as professional with external attendees

Giving attendees a clear option in case online call quality suffers
