Services Hosted on Cloud Networks

Some services are hosted on cloud networks such as Azure. Because the IP ranges are subject to change at the discretion of Microsoft, we recommend whitelisting using FQDNs rather than IP addresses. If IP address-based access control is required, it is customer's responsibility to keep the allowlist up to date, for example, by writing a custom script to always capture the latest data. For the IP address ranges for Public Azure, visit this page at https://www.microsoft.com/en-us/download/details.aspx?id=56519.

Push servers hosted by CounterPath

IP addresses and domain names

Clients should automatically route to the correct nearest regional server, but we recommend ensuring that ALL addresses are accessible in case of traveling users, etc. Please also note that IP addresses may change in the future; if you manually configure your firewall/etc. for these addresses and experience issues in the future, please revisit this page to find the latest information.

Only IPv4 SIP servers are currently supported for calls involving the push server. The Bria mobile client will support IPv6-only networks utilizing DNS64/NAT64 when communicating with IPv4 SIP servers.

Current domains and IP addresses

The following domains and IPs will remain in use during the transition. Keep them in your firewall allowlists until you're advised to remove the access.
