Addition of Microsoft Teams Direct Routing Infrastructure in Australia
As part of Teams Direct Routing expansion Microsoft
has deployed new instances of Microsoft Teams Direct Routing infrastructure in
Australia. Two new IP addresses (52.114.16.74 and 52.114.20.29) for
customers connecting to this new Australian infrastructure.
The SIP signaling connection points for Direct Routing
are the following three FQDNs:
sip.pstnhub.microsoft.com – Global FQDN –. When the SBC sends a request to
resolve this name, the Microsoft Azure DNS servers return an IP address
pointing to the primary Azure datacenter assigned to the SBC.
sip2.pstnhub.microsoft.com – Secondary FQDN – geographically maps to the
second priority region.
sip3.pstnhub.microsoft.com – Tertiary FQDN – geographically maps to the
third priority region.
IP Address of the FQDN’s are listed in Microsoft
