Agenda What is Phone System Endpoints and Clients Phone System features Connectivity to PSTN Summary and resources

What is Phone System?

Anatomy of a traditional PBX deployment PBX is a phone system PBX provides voice features to its users Connects (switches) calls between users Sends/receives calls to/from the PSTN End points and clients End points and clients consume the PBX features Trunk Connects the PBX to the PSTN network Connectivity PBX End points PSTN Trunk

Taking the voice to the cloud Endpoints and clients All Teams clients – Windows, Mac, Web (currently Edge only), iOS, Android, IP Phones Will be able to leverage PBX features in addition to other Teams features Phone System provides PBX features For all users on Teams with appropriate license “Trunks” Calling Plan Direct Routing

Office 365 Service Level Agreement Financially accountable For availability and quality Skype for Business covered in Office 365 SLA Included with every Office 365 subscription Availability of IM and Meetings Availability of PSTN Calling and Conferencing Ensuring ever call has great quality Requirement for Quality SLA: use certified IP phone with wired Ethernet connection Media issues need to be due to Microsoft networks Monthly uptime % Service credit < 99.9% 25% 99% 50% <95% 100%

Connecting to the PSTN

Anatomy of a traditional PBX deployment PBX is a phone system PBX provides voice features to its users Connects (switches) calls between users Sends/receives calls to/from the PSTN End points and clients End points and clients consume the PBX features Trunk Connects the PBX to the PSTN network Connectivity PBX End points PSTN Trunk

Connecting Phone System to the PSTN Calling Plans First party offer from Microsoft available in specific countries as regulated utility Third party calling plan in Australia with Telstra Completely cloud-based with no required infrastructure on-premises Tightly integrated with Office 365 and Phone System New phone numbers from Microsoft or port existing numbers Calling plan availability: https://aka.ms/calling-plan-availability Direct Routing Connecting Office 365 with the customer infrastructure No need to port phone numbers Session Border Controller (SBC) on-premises integrates with existing PSTN connectivity SBC can also be partner hosted

Calling Plans PSTN connectivity provided directly by Microsoft (Exception: Telstra provides Calling Plan in Australia) Single contract for all features including PSTN calling No on-premises equipment required No SBC for connectivity required Meets legal requirements As necessary to participate in country/region Domestic and international calling plans Different options for calling plans to meet your users’ needs

Direct Routing Directly Route dial tone to Teams Users Direct Routing allows customers to connect their phone trunks directly to Office 365. Customers can work with their local Telecommunications providers to enable Microsoft Teams users to make and receive telephone calls. PSTN Provider Phone System Voice Trunk Internet 3 rd Party Voice Apps (supported by certified SBC Partners) Phone # Ranges Certified Session Border Controller(s) Interoperability with 3rd party systems Direct Routing allows customers with users in the Microsoft cloud to continue using 3 rd party systems such as PBXs, Call Center, and Analog Telephony Adaptors (ATA) helping preserve key investments. Office 365 & Teams

Networking considerations Three network segments Enterprise Network: On-Premises and cross facilities WAN; Customer managed Interconnect: Internet, Express Route; Customer selected Office 365 Network: Microsoft managed global, low latency network optimized for Teams On-Premises network and devices Interconnect Network Office 365 Network

Summary

Planning considerations User locations Calling Plans available in selected markets https://aka.ms/calling-plan-availability Existing PSTN connectivity Direct Routing allows to use existing PSTN infrastructure Allows using legacy PBX and/or existing telephony contract On premises component vs. cloud only Are you able/willing to host and manage an SBC on premises Mix and match Some users can leverage Calling Plans while others use Direct Routing Users can combine Calling Plans and Direct Routing
