Deploy multiple sites in Cloud Connector

Learn about deploying multiple PSTN sites in Cloud Connector Edition.

This section describes how to deploy multiple Public Switched Telephone Network (PSTN) sites. Sites are deployed one at a time using the same steps as deploying a single site. This topic describes the considerations for and differences between sites in a multiple site deployment.

SiteName=Site1
[EdgeServer]
InternalMachineName= cc-edge1
InternalPoolName=cc-edgepool
InternalMachineIPs=192.168.0.241

ExternalSIPPoolName=access1
ExternalSIPIPs=192.168.1.4

ExternalMRFQDNPoolName=mr1
ExternalMRIPs=192.168.1.4
ExternalMRPublicIPs=23.99.115.35

PSTN Site 2

[Common]
SiteName=Site2
[EdgeServer]
InternalMachineName= cc-edge2
InternalPoolName=cc-edgepool
InternalMachineIPs=192.168.0.242

ExternalSIPPoolName=access2

The shared folder for preparing High Availability (HA) is per PSTN site. The shared folder must be different between PSTN sites. Do not use the same shared folder for multiple sites.>
