Skype for Business

PSTN Conference
A PSTN conference is when an individual dials into the conference with a public switched telephone network (PSTN) phone. These users have access to and can partake in the audio portion of the meeting. PSTN conferencing is beneficial when Internet connectivity is low, if a user does not have access to the Internet or a PC.

PSTN Calling
Members in your organization are able to make phone calls directly from within Office 365. This is done on the PSTN which is an add-on to Skype Cloud PBX. Phone numbers are assigned to employees allowing them to make calls within and out of the organization. Features such as hold, mute, call transfer, call forward and emergency calls are available.

PSTN Domestic Calling vs. International Calling
PSTN Domestic Calling: : Make calls within the country or region in which a user has been assigned Office 365.
International Calling: Able to make calls to 196 countries worldwide in addition to the country they were assigned Office 365 in.

What is Cloud PBX?
With Cloud PBX you can make inbound and outbound calls using Skype for Business, your existing phone lines or the Skype for Business PSTN calling. Using Cloud PBX and Skype for Business allows you to perform tasks such as placing, receiving, transferring and muting/unmuting lines or the Skype for Business PSTN calling. You can choose to host your PBX system entirely in the cloud, or choose to do a hybrid deployment meaning half in the cloud and half on premises.
