Office 365’s complete cloud communication provides you with one platform for meetings and voice.
Reduce your voice and conferencing costs while connecting to meetings and each other from virtually anywhere, on any device.
Office 365 E5 as a combined offering is far cheaper than buying individual products and solutions. When you consider that when Voice and Advanced Threat Protection are combined you get advanced eDiscovery, Power BI, etc. It’s a much easier way to unlock value for your business.
PSTN Conferencing provides a dial-in conference number to meeting participants, so they can easily connect by phone from anywhere they do not have Internet access. PSTN Conferencing simplifies the meeting process by ensuring that even participants without a stable internet connection can access a Skype for Business meeting through dial-in or dial-out conferencing.
PSTN Calling is an add-on to Cloud PBX that provides domestic and international calling services for businesses directly from Office 365. Instead of contracting with a traditional telephony carrier and using an on-premises IP-PBX, you can purchase Cloud PBX and add-on PSTN Calling for a complete enterprise-grade telephony experience for your business.
