As a general recommendation it is advised not to do any outbound IP traffic filtering. However, in situations where that's not possible such as when PBXact is deployed to secure environments. it is possible to restrict outbound only to needed IPs and ports.

In this situation, upgrading the PBXact software can be difficult because PBXact needs access to many servers like our mirror server to upgrade modules and other dependent servers to upgrade/download dependent libraries.


Please find below list of servers which is minimum required to allowed for the duration of upgrades.


Admin Note

IPs associated with noted URLs can change due to dynamic dns, so please ensure URL IPs are always accessible.


https://mxtoolbox.com/SuperTool.aspx can be a useful tool to do the DNS lookup.




→ For a list of ports your may need to open on your PBX, please see Ports used on your PBX
