Call Bypassed
Incoming PSTN Call
Lync On-Premises
An incoming PSTN call is routed to the onpremises gateway, then moves to the onpremises Lync Server
The number is located via Reverse Number
Lookup (RNL), routed to Lync Online, and then
routed to the Lync Online endpoint
Media flows using the optimal path between the
client endpoint and PSTN infrastructure/MS
5a is the media path when bypassed

Incoming PSTN Call (Internet
User)
An incoming PSTN call is routed to the onpremises gateway, then moves to the onpremises Lync Server
The number is located via RNL, routed to Lync
Online, and then routed to the Lync Online
endpoint (on the Internet)
Media flows using the optimal path between the
client endpoint and the MS
Most likely through the on-premises Edge
Server; if not, between the online and onpremises Edge Server

Outgoing PSTN Call
Lync On-Premises
Call Bypassed
An outgoing PSTN call request is placed by a
user hosted on Lync Online
An RNL is performed and fails to associate a
user
The request is assumed to be a PSTN/PBX call
and is proxied to the on-premises Lync Server
Voice policy enforcement and call authorization
are performed on-premises
The call is routed to PSTN egress and media
bypass setup to client

The client retrieves the location policy and
determines its location from the Location
Information Service (LIS) Server during sign-in
When an emergency call is placed, Lync Online
routes the request across to the on-premises

The on-premises Lync Server routes the
emergency call to the appropriate E911 service
